Dry function in an air conditioner: what it is and why it is needed, features and principle of operation

Air conditioning is essential for maintaining comfort in our homes, particularly in the sweltering summer months. But not everyone is aware of all the features available on our air conditioners. The "dry" feature is one such element that is frequently misinterpreted.

An air conditioner’s dry function lowers the humidity in your house without drastically decreasing the temperature. Even in situations where the temperature isn’t very high, high humidity can make the air feel warmer and more uncomfortable. By eliminating surplus moisture from the air, the dry function contributes to the creation of a more comfortable indoor atmosphere.

Making the most of your air conditioner’s capabilities can be achieved by being aware of how the dry function operates. In essence, the compressor and fan of the air conditioner work together to pull in humid air from the room when you switch to the dry mode. Moisture condenses on the evaporator coils as air flows through the unit, collecting in a drainage pan or being released via a drain hose.

Why would you want to utilize the dry function, then? Reducing humidity can be useful in addition to increasing comfort. Reduced humidity can also help keep wood furniture and fixtures from warping or cracking, stop the growth of mold and mildew, and even lower energy costs because dry air feels cooler and you can raise the thermostat without feeling uncomfortable.

Device and principle of operation of the air conditioner with dehumidification

Let’s first explain the general construction of air conditioners in order to comprehend the dehumidification option’s operation.

The refrigerant’s changing properties serve as the foundation for the device’s operation.

It goes through four phases: expansion, vaporization with cold release, condensation with heat release, and compression.

The two blocks that make up a modern multifunctional split system are the internal and external blocks.

Parts of the external apparatus:

1. A fan blows air into the system.
2. Condenser cools and condenses Freon.
3. Compressor compresses freon, provides general circulation of working fluid through the system.
4. The capillary tube expands the working substance.
5. Four-way valve. Provides a change in the refrigerant flow circuit for the heating function.
6. Filters clean the air streams entering the condenser, preventing contamination of the unit elements.

The following components make up the indoor unit:

1. Front panel with filter allows air intake from the room.
2. Filter system.
3. Fan.
4. The evaporator cools and heats the air.
5. Blinds regulate the direction of air flow.
6. Control board.
7. Indicator panel.

The working principle of air conditioners for heating and cooling processes. The compressed gaseous working material is routed through tubes to the condenser from the compressor. As a result of pressure, condensation occurs and heat is released. Pressure is decreased by directing heated freon through a capillary tube. The evaporator is filled with the gas-liquid mixture. The Freon cools in the evaporator and distributes the cold to the air streams that enter the space. The compressor receives the gaseous refrigerant once more. It results in a closed cycle of the working substance’s movement.

The working substance movement circuit is switched to the heating mode. Within the internal unit, freon is heated with heat release and cooled with heat intake in the external unit.

Principle of air conditioner operation

The following is the air conditioner’s operating principle:

• Split-systems have an indoor and an outdoor unit. When the air conditioner operates in cooling mode in the outdoor unit, Freon (refrigerant) is pressurized into the radiator. The pressure causes it to heat up. The heat from the radiator escapes to the atmosphere.
• The cooled Freon is directed to the indoor unit. Here it expands sharply, due to which its temperature decreases, and the air in the room gives heat to the refrigerant.
• Condensate appears on the cold heat exchanger, which is cooled water from the room air.
• The liquid is then discharged to the outside.

It is helpful to think about the basic principles underlying the various modes of operation of air conditioners in order to comprehend how they dry or humidify the air.

What is dehumidification mode in an air conditioner?

The air conditioner’s dehumidification mode is a feature that aids in bringing the air’s humidity down to a comfortable level. Simultaneously, an innovative mechanism eliminates surplus water from the airflow while preserving a pleasant ambient temperature. The range of 40 to 60% is the best indicator of air humidity in living rooms.

The increase in this value results in:

• making people feel worse;
• the development of fungi on the wall surface;
• of pathogenic microorganisms.

By reducing the amount of moisture in the air, this mode helps people feel more comfortable. Systems in the "premium" or "medium" class come with this feature by default. On remote controls, a unique icon indicates it.

Special features

Not all models incorporate them. But when put to the test, a large number of them prove to be highly intriguing and practical.

1. Comfort settings allow you to turn on the equipment to calculate the optimal temperature balance. The technique itself will make the necessary adjustments and give the optimal results. Usually for heating it is an indicator of 20 degrees, and for cooling is used 25 degrees.
2. Cleaning the room from the dust coming in with the outdoor air is also useful. Usually a variety of filters are used here – coarse filters (removes large dust particles) and fine filters (which work even with flower pollen). There are also filters that remove the smoke odor.
3. 3D flow is used to deflect the air flow vertically. This will help the user not to catch cold. And at some models the device itself determines the location of the remote control (function "Ifeel") and sends air masses in its direction.
4. Ionization implies saturation of the microclimate with negatively charged ions. This improves the user"s immunity and well-being. According to some people, it feels like a sea breeze.
5. Low temperatures outside the window? Then it"s time to turn on the "defrost" of the outdoor unit. The refrigerant will collect all the cold that came with the street air masses.
6. Finally, self-diagnosis is one of the most useful functions. The unit itself will automatically detect its own malfunction – this will help to quickly deal with the problem and prevent breakdowns.

Comfortable stay in the room with air conditioner

The room’s temperature is primarily affected by the air conditioner that is turned on, but it’s not the only factor.

The air conditioner does more than just keep the temperature at the desired level; it also dehumidifies the air. This results in the possibility of dryness of the throat and nose mucous membranes. Some people experience discomfort in the form of scratchy throats and runny noses.

40–60% humidity is ideal. The hygrometer is used to measure this. Contemporary gadgets report humidity as well as other crucial aspects of the microclimate.

You can prevent this by setting up a humidifier in the space. Increasing your water intake is also advised as it will keep your mucous membranes from drying out.

Air conditioner Dry mode – dehumidification

The air conditioner’s control panel indicates the dehumidification function as "Dry." Individuals who reside in areas with elevated air humidity may find this option beneficial. After absorbing moisture for ten minutes in the activated dehumidification mode, the fan is shut off for five minutes, and then the turbo ventilating mode is turned on for two minutes.

In split systems, the dehumidification mode not only gets rid of extra moisture in the air but also keeps mold and fungus from growing.

What is the purpose of dehumidifying function in the air conditioner?

An air conditioner dehumidifier is required at:

1. Living in areas of high humidity.
2. Placement in the apartment of devices that excessively humidify the air.
3. The harmful effect of excess humidity on household appliances and books.
4. Increased risk of mold fungi appearance.
5. Dampness in the rooms.
6. Flooding due to burst pipes.

The way that different climate systems dehumidify the air varies! In rooms with high relative humidity, drying requires a strong method that works fast.

A subset of the populace finds it difficult to cope with elevated air humidity levels. This raises the chance of getting allergies, asthma, or rhinitis in addition to exacerbating pre-existing conditions. Consequently, it makes sense to equip the space with a "dehumidifying" air conditioner.

Why you may need dehumidification in your apartment?

Increased humidity or increased dryness are the two types of climatic discomfort that can happen in living quarters.

If using a humidifier to solve the problem is all that is required in the first scenario, there is typically no clear solution to the issue in the second. It is possible to solve the problem of dehumidifying the air in your apartment provided you select the best equipment for your space and seek advice from professionals.

It is only necessary to dehumidate the apartment’s air when the humidity level rises above 60%. This is required to guarantee that the air satisfies hygienic requirements.

The table displays the ideal air parameter values for Ukraine’s comfortable air conditioning.

It takes the right amount of humidity, air exchange quality, and temperature to create a beneficial microclimate in the home.

The presence of moisture in the space promotes the growth of mold and fungus, makes them more uncomfortable for people, and causes them to appear. It becomes necessary to control the room’s moisture content under such circumstances. When the humidity level is higher than the ideal range of 30–60%, air dehumidification is necessary.

In residential rooms, dehumidifying the air is usually not necessary. The only room with excessive air humidity is the bathroom. However, exhaust fans—which are made to thoroughly remove moisture, different vapors, and offensive odors from bathrooms—are available for this purpose.

How to dehumidify indoor air?

There are specific guidelines regarding moisture intake, such as calculating the amount of moisture to remove and the ideal relative humidity for each room. For example, the indoor unit’s air conditioner should provide one liter of moisture intake every hour, so three liters of moisture intake are required.

The apartment’s air humidity cannot be reduced by the air conditioner by itself. As a result, installing additional equipment in the form of stationary and mobile dehumidifiers is required. But, as air dehumidification is usually provided for spaces with high humidity (such as swimming pools and cellars), there is typically no need for it in apartments.

For residential spaces, air conditioning or ventilation units are therefore more than adequate.

Conditioning

In the summer, every air conditioner unit does the dehumidification job. Since all air conditioners operate on the same principles, the capacity of the indoor unit is more important than the brand or type of unit. The indoor unit will absorb more moisture the more powerful it is.

In order to establish standard parameters for moisture content (specifically, dehumidification), a standard split-system air conditioner is utilized.

Compressor-condensing units (CCUs), or outdoor air conditioner units, and indoor units make up a split system. If the process of cooling the air involves dehumidification, there is an evaporator in the internal unit and a condenser in the external unit. Moisture and recirculated air are drawn in by the evaporator, which is housed in the air conditioner’s indoor unit.

Freon absorbs the potential energy of the air in the room by entering the evaporator of the indoor unit. After that, it travels to the compressor, where it is compressed and heated up. The gas enters the condenser, the air conditioner’s external unit, where it gains temperature and releases pressure into the surrounding air. The throttle-valve releases the pressure.

The procedure is then repeatedly carried out.

When the air conditioner runs on the cold setting, the room’s air becomes dehumidified. Because heat is taken in by the unit when it removes air from the room; this heat is then cooled, and the dew point is reached. And the air gets progressively drier as that moisture enters. As a result, the air conditioner only dehumidifies when it is in the cooling mode. Additionally, only outside the room will the air be dehumidified when in heating mode.

A more effective way of dehumidifying the air in a dwelling is intensive ventilation, which is carried out with the help of a supply and exhaust unit. As a rule, it includes powerful exhaust fans in the bathrooms and toilets. High-quality ventilation will provide organized air exchange in the room, and in areas of high humidity (bathroom) or where there is a high probability of dampness (dressing room or utility room) will eliminate all excess moisture. The optimal level of air humidity in the apartment will be created by special exhaust fans with humidity sensor, which fix the state when the level of moisture exceeds the norm. For an apartment or similar living space, this option for getting rid of excessive humidity is quite an optimal solution.Humidity in the living space can be destroyed by household dehumidifiers. These devices are designed to draw in air with a high concentration of moisture, which is treated and subsequently discharged fresh and clean from the device. Dehumidifiers can be mounted either on the wall or on the floor. The market is represented by leading manufacturers: Dantherm, Mitsubishi Electric, Cooper&Hunter. However, since such situations do not occur in an apartment, it is more appropriate to provide effective ventilation from the outset. It will fight the causes of high humidity in advance, as well as create a favorable atmosphere and comfortable climatic conditions in the whole house.

Advantages and disadvantages of dehumidification mode

There are drawbacks to the climate system’s air drying process itself.

1. Breakage of the device leads to loss of "Dry" function.

The air conditioner won’t be able to dry the air if the unit breaks down.

1. It is not desirable to use in winter time.

The dehumidifier will remove the air’s pre-existing low moisture content in the winter (the heating system will dry the majority of it). Skin and hair issues are exacerbated by an absence of liquid in the atmosphere.

1. Excessive number of options interferes with the basic functions of the climate system.

An extensive list of functions on the air conditioner adds to the unit’s increased load. The equipment’s overall efficiency may suffer as a result. The best models to purchase are those with the most features for everyday use in the home.

1. Reduced effectiveness of the "temperature rise" option.

You’ll be curious about: The air conditioner’s features and power selection

The "drying" function will not be able to fully activate the "heating" program during the winter.

There are benefits to the "Dry" option despite its numerous drawbacks.

1. Comfort in the room.

By using this mode on and off on a timely basis, you can adjust the room’s microclimate to suit the needs and preferences of every family member.

1. Space saving.

Where water goes from the air

All you need to do to understand where moisture disappears and why air conditioners dry the air is to recall the evaporative type refrigerating machine’s operation principle.

The working body of the air conditioner, which is a readily vaporized liquid or gas, allows it to cool down when it expands sharply, just like any other refrigerator. This process is carried out in a unique evaporator system with a ribbed radiator, through which the air that needs to cool is driven by an integrated fan.

Everybody has experienced "sweating" windows or cold water pipes. This is the result of water vapor dispersing in the atmosphere and condensing into water droplets on the chilly radiator surface. The only difference in our situation is that the built-in pump expels the condensed water through a drainage pipe.

The more the temperature differential between the air and the evaporator, the more water condenses in the water trap, if any regularity is discernible. For instance, the air conditioner can produce up to one liter per hour during the summer.

When and how to activate the dehumidification mode in the air conditioner

Since it is well known that high humidity makes it harder to tolerate heat, turning on the "Dry" option in these situations will help you breathe more easily. If necessary, you can turn it on by clicking on the desired menu line or by pressing the corresponding button on the remote control. By selecting the "Dry" option, stuffiness disappears and the air becomes more comfortable to breathe. Additionally, there is no change in the background temperature!

The majority of home split systems can eliminate too much moisture from the air, reducing the possibility of numerous negative effects on the body and apartment. Thus, the "Dry" mode will be activated when the room is set to a predetermined temperature. A sensor senses when the humidity reaches the ideal level and sends out a signal to lower the fan speed.

When the "drying" option is activated, a unique valve helps maintain a comfortable temperature for the residents in the room. Its precise actions lead to the heat exchanger’s freon flow being blocked.

For sure, having the "drying" function on the air conditioner is a huge benefit to its owners. Such a unit is only worth using when absolutely necessary, as dry air can have a harmful impact on many interior furnishings as well as people’s health.

Step-by-step instructions for switching on the air conditioner in the drying mode

Ensure that the air conditioner is connected to the "mains" by plugging it into the socket or turning on the corresponding "automat" on the electric panel before turning it on.Subsequently, grab the remote control and adhere to the detailed instructions provided to initiate the dehumidification mode:

1. Turn on the air conditioner with one press on/off button.
2. Then press the Mode button several times until a drop or the word Dry appears on the display of the remote control.
3. Further, by buttons Temp or arrows we choose the necessary temperature. For example, we set 25 so that the conditioner does not lower the temperature in the room below +25 degrees Celsius. Т.к. In the drying mode of the air conditioner its main task is to dehumidify, it is not a fact that it will maintain the set temperature.
4. If it is necessary to change the fan speed, press the "Fan Speed" button (there can be "Fan" or "Speed" buttons).
5. If you need to change the direction of the louver flow, look for the Swing button.

Long-term operation of the air conditioner in dehumidification mode

The air conditioner runs for ten to fifteen minutes while drying, and then it turns off for five minutes. After that, the fan runs for two to three minutes. The cycle is then repeated after that.

A hygrometer is a useful tool for managing the room’s drying process. You can switch off the unit or activate the cooling system as soon as you notice that the humidity has decreased.

Over-dried air is a risk when operating the dehumidification system for an extended period of time. The skin dries out, the mucous membranes start to dry out, and there is a perspiration in the throat. Consequently, if this function is not required, it is not a good idea to leave it on all the time.

Structure and peculiarities of air conditioner operation

Examining the air conditioner’s device is essential to comprehending how it operates. Refrigerant serves as the machine’s basic material. This substance may shrink, condense, increase, or boil out when exposed to cold radiation while it is in operation.

The 21st century saw the development of split-systems, which have indoor and outdoor units. What components make up the system’s exterior portion are there:

• fan, which drives the unit"s air;
• condenser. It is responsible for cooling and condensation of Freon;
• blower, which is engaged in compression. Thanks to its work, the liquid is circulated throughout the system;
• capillary hose. It increases the working material in volume;

4-position valve. in charge of adjusting the flow pattern of the refrigerant and heating the filter. They are required to purify the incoming air. The purpose of its operation is to keep dirt out of the unit.

The apparatus’s internal parts are made up of the following parts:

• leading panel consisting of a filter for air intake;
• filter system;
• fan;
• Heat exchanger for cooling and heating the air;
• curtains to regulate air flows;
• control system;
• panel with indicators.

How does an air conditioner heat and cool air? The compressor is the first part of the system; from it, gas is directed through pipes to the condenser. Heat is produced as a result of the pressure’s action.

Freon at a high temperature is inserted via a capillary tube. There’s less force applied. Gas and liquid are combined and sent to the heat exchanger. The mechanism’s cycle of movement is completed when the refrigerant is inserted into the blower.

The contours of the substance’s movement alter when it heats up. Warm air intake reduces freon temperature from the outside in.

Within the block system, heat transfer and air heating are accomplished.

How to turn on the air conditioner "for drying"

Turning on the air conditioner’s Dry function is required to begin the dehumidification process (Dry stands for "dehumidification"). The air cooling mode and this mode are extremely similar.

• the radiator of the indoor unit is cooled.
• Warm air is in contact with its surface. As a result, moisture contained in the air settles as condensate on the radiator surface.
• the unit collects condensate and discharges it outside the room using a drain hose.

Although it isn’t always required, this algorithm should ideally result in a drop in the room’s temperature. The "on-dry" device functions as follows to prevent this:

• the air cooling function is activated.
• When the radiator of the indoor unit becomes cold enough, the fan switches to low speeds.
• the radiator is slowly blown out, moisture condenses on it, but the air temperature remains practically unchanged. The fan rotates too slowly for the room to cool down noticeably.
• Also, to prevent cooling of the room, the fan is periodically stopped.

Purpose of the drying option in an air conditioner

The precision required for heating and cooling is provided by the functionality of contemporary air conditioner models. Many of them also offer ways to eliminate moisture from the air. Let’s examine the necessity of an air conditioner’s drying function.

Device and principle of operation of the air conditioner

Let us first discuss the general construction of air conditioners in order to comprehend the drying option’s working principle.

The mechanism of the device involves altering the characteristics of the working material, refrigerant.

Compression, condensation with heat release, expansion, and evaporation with cold release are the four states it goes through.

Air conditioner design and operation principle

Two blocks make up modern multifunctional split-systems: internal and external.

Parts of the external apparatus:

1. The fan blows air into the system.
2. The condenser cools and condenses Freon.
3. Compressor compresses Freon, provides general circulation of working fluid through the system.
4. Capillary tube expands the working substance.
5. Four-way valve. Enables the refrigerant flow circuit to be changed for the heating function.
6. Filters clean the air streams entering the condenser, preventing contamination of the unit components.

The following components make up the internal unit:

1. The front panel with filter allows air intake from the room.
2. Filter system.
3. Fan.
4. The evaporator cools and heats the air.
5. Blinds for adjusting the direction of air flow.
6. Control board.
7. Indicator panel.

The working principle of air conditioners for heating and cooling processes. The working substance, in its compressed gaseous state, is directed through tubes to the condenser from the compressor. As a result of pressure, condensation occurs and heat is released. By passing through the capillary tube, the heated freon lowers the pressure. The mixture of gas and liquid enters the evaporator. The Freon in the evaporator is cooled, and this cooling effect is transferred to the airflow entering the room. The compressor receives the gaseous refrigerant once more. The working substance movement is achieved in a closed cycle.

The working substance flow circuit is switched to the heating mode. Within the internal unit, freon is heated with heat release and cooled with heat intake in the external unit.

Purpose of the drying function in the air conditioner

Manufacturers promote the air conditioner’s dry air supply feature as a major functional advantage. It is not always required, but it is.

Dehumidification mode: the icon with three drops

When one needs to use the drying option:

1. Living in regions with high humidity. The supply of humid air into the room will cause damage to furniture, doors, books, household appliances, etc. д. On the walls and in the corners of the room, favorable conditions for the development of fungi and mold are created. The room atmosphere becomes musty.
2. Flooding of the room after burst pipes or breakdown of plumbing systems.
3. The room contains equipment that excessively humidifies the air. The room is intended for work with the release of large amounts of liquid into the air. It is worth specifying the functionality. Many air conditioners will not be effective in dehumidifying rooms with abundant moisture (swimming pool, etc.).).
4. Poor tolerance of high humidity by the organism, presence of a disease for which such climate is contraindicated.
5. It is recommended for the health of all people, if the humidity level in the room deviates from the optimal values – 45-65%. Allergic reactions, asthma or rhinitis are more likely to develop if there is excessive moisture in the room. It is impossible to live in over-dried air. In such a situation the probability of problems with respiratory tract, skin, general condition of the body increases.

Particular attention needs to be paid to the humidity regime in apartments occupied by young children.

It is important to use the moisture removal option carefully. It’s crucial to monitor the moisture level while the function is running and to only use it when the level is noticeably exceeded or there is a persistent "upper" deviation from the average. It must be set to operate at 50% humidity and between 18 and 20 degrees Celsius.

How drying works in an air conditioner

This type of equipment operation, in which a unique system extracts moisture from the moving air and introduces it into the space, is referred to as air drying. There is no decrease in temperature.

Principle of operation of the drying mode

The Dry option on the air conditioner must be turned on (the word "dehumidification" in Russian) in order to activate the drying function. The Dry option may be displayed on the touch panel as a separate line or as a button, depending on the model. Remote controls can also be used to activate the option. The system model’s technical data sheet contains specific instructions on how to use the option.

In theory, this mode is comparable to the air cooling feature.

It operates using the algorithm listed below:

• the radiator of the indoor unit is cooled;
• the air blown by the fan comes into contact with the radiator surfaces and gives off its heat;
• moisture from the flowing gas precipitates as condensate on the radiator walls;
• special tubes collect the liquid and discharge it through a drain hose, which must be installed next to a special container for water collection;
• the air entering the room loses temperature and cools the climate in the room.

The humidity in the rooms decreases when the air conditioner is drying.

The following guidelines govern how the drying option functions:

• the cooling system is switched on;
• When the radiator reaches a certain low temperature, a sensor is activated and the fan is commanded to reduce its speed;
• the air flow rate is reduced;
• condensation continues;
• the discharge is too slow and the dehumidified air does not have time to lower the room temperature;
• When certain parameters of temperature drop are reached, the sensor gives a command for complete temporary shutdown of the fan;
• the fan is periodically switched on and off.

A unique valve aids in keeping the room at a comfortable temperature while drying. The heat exchanger’s Freon flow is stopped by a valve.

The air conditioner’s drying mode can be turned on automatically.

When dehumidifying, the air conditioner’s approximate mode of operation is:

• Dehumidification works for 10 minutes;
• 5 minutes the unit is switched off;
• 2 minutes the fan runs hard;
• cycle repeats.

Pros and cons of dehumidification mode

There are advantages and disadvantages to the air conditioner’s dehumidification mode.

1. No need to install an additional dehumidifying appliance.
2. Functionality of the split-system allows to provide the most comfortable mode, with fine adjustment of the main parameters: temperature, humidity.
3. Presence of full functionality in one device allows to save free space.
4. Drying is used as needed. The presence of a climate control option increases the level of comfort.

1. It is not recommended to use the option in winter, t. к. heating system of the house leads to reduction of moisture concentration in the atmosphere. Additional dehumidification will create unfavorable microclimatic conditions in the room.
2. In winter, when the air conditioner works on heating, switching on the drying function will lead to decrease of efficiency of temperature increase in the house.
3. Combining a wide range of functions in one unit may affect the performance of the main functions. Auxiliary options increase the loads on the equipment, which affects the period of their effective operation. It is important to study in detail the technical parameters of the equipment when buying, choose proven models and manufacturers.
4. If the air conditioner breaks down, the drying function will disappear. Having a separate device will not lead to such a problem.

An effective device is an air conditioner with a drying feature. But only in cases where this option is required. This feature is not required if the room’s air is dry. It makes financial sense to purchase a standard air conditioner that can be used for both heating and cooling.

How to set the temperature correctly in summer?

Comfort is a highly individualized term. While thirty degrees may seem pleasant to some, it may seem like absolute hell to others. While SanPiN 2.1.2.2645-10, which controls the temperature in residential buildings during the warm season, has requirements, the legislation does not contain any norms regarding the temperature at which air conditioners must operate.

First and foremost, we should begin with this document. SanPiN 2.1.2.2645-10 specifies that a room’s ideal temperature is between 22 and 25 degrees Celsius. It is also advisable to read the air conditioner’s instruction manual, as it will specify the ideal temperature to set.

The ideal temperature for the air conditioner will be roughly 25 degrees if the outside temperature is 30 degrees. Deviations up to 20–28 degrees are permitted with SanPiN 2.1.2.2645-10. However, the vast majority of people will find this temperature uncomfortable, so it is best to leave the air conditioner off.

Certain air conditioner models have the ability to automatically regulate the room’s temperature according to the current outdoor temperature in degrees.

It’s advised to adjust the desired temperature gradually.

During a heat wave of 30 degrees, it will appear like this:

• Turn on the air conditioner and let it cool the room to 28 degrees;
• After 10-15 minutes you can reduce the temperature to 25 degrees;
• After 30-40 minutes the temperature can be reduced to 23 degrees Celsius.

Cooling the air below 23 degrees is not advised because it causes a person’s blood vessels to constrict.

Although this is a natural defense against hypothermia, it hurts because it dries out the mucous membranes in the eyes, nose, and throat.

Pros and cons of dehumidification mode

There are advantages and disadvantages to the air conditioner’s dehumidification mode.

1. There is no need to install an additional dehumidifying device.
2. Functionality of split-system allows to provide the most comfortable mode, with fine adjustment of the main parameters: temperature, humidity.
3. Presence of full functionality in one device allows to save free space.
4. Drying is used as needed. The presence of the option to adjust the microclimate increases the level of comfort.

1. It is not recommended to use this option in winter, because. к. Home heating system leads to reduction of moisture concentration in the atmosphere. Additional dehumidification will lead to creation of unfavorable microclimatic conditions in the room.
2. In winter, when the air conditioner is working on heating, switching on the drying function will lead to a decrease in the efficiency of increasing the temperature in the house.
3. Combining a wide range of functions in one appliance may affect the performance of the main functions. Auxiliary options increase the load on the equipment, which affects the term of their effective operation. It is important to study technical parameters of the equipment in detail when buying, choose proven models and manufacturers.
4. If the conditioner breaks down, the possibility of drying will disappear. The presence of a separate device will not lead to such a problem.

Yes, this is the central claim of your paper:The comfort level of your house can be significantly improved by being aware of the dry function on an air conditioner. By eliminating extra moisture from the air, this feature helps regulate humidity and improves the atmosphere during hot and muggy weather. The dry function increases the overall efficiency of your air conditioning system while also enhancing comfort by controlling moisture levels. In order to help you maintain a comfortable and energy-efficient home, this article will explore the features, significance, and working principle of the air conditioner’s dry function.

Whether dehumidification mode is necessary in the air conditioner?

In any case, the unit will dry the air; having a separate Dry function will let you remove extra humidity without using the air conditioner to cool the space.

The following circumstances will benefit from this option:

• When the high moisture content makes it difficult to breathe in the heat and creates a tropical effect.
• If you live in a humid climate.
• After flooding of the apartment by neighbors.
• When there is high humidity in the apartment due to poorly working ventilation.

It is much harder to tolerate high temperatures in a damp room. There is not enough time for the body to release heat, increasing the risk of heat stroke.

To feel better, the humidity should be lowered by at least 10%. 30% to 60% of the parameters are thought to be the ideal range.

By being aware of how the air conditioner’s air dehumidification mechanism operates, you can control the room’s humidity (assuming it is high). With such a device, the moisture content cannot be raised. All "humidifying type air conditioners" only produce "tropics," not actual air conditioning.

The norm of air humidity in the room

The acceptable range of air humidity in living rooms, according to current sanitary rules and regulations, is 40% to 60%. The natural index is approximately 70% in the average climatic zone. In a few hours of operation, the refrigeration unit can lower it to 20–30%.

You can use the Sahara Desert as a point of comparison. Here, the humidity ranges from 30% to 50%. This place is hot and dry. There is a stuffy feeling in the room due to the high temperature and humidity.

The human condition is impacted by low humidity of air masses, which has an effect on:

• the ability of the lungs to absorb oxygen;
• skin elasticity;
• the condition of mucous membranes;
• general well-being;
• performance;
• Allergic reactions to synthetic fibers, wool, and dust that were previously associated with water.

Long-term low humidity causes paper to become brittle, wooden objects to dry out, and book glue to lose its basic qualities.

On the other hand, dry air is less dangerous than high humidity. To be harmful to humans, the air must be extremely dry. This is very challenging to accomplish with a typical home air conditioner.

When split systems cool down, the air inside becomes dry. Professional gadgets are equipped with a humidification feature. But their price is several times higher.

Where moisture goes when air is dehumidified?

To answer the question "where does the moisture go when dehumidifying the air?"If the temperature is low, it should be understood that air conditioning is usually used to reduce the temperature of the air. However, as the temperature drops, so does the humidity level, and how! To understand how this happens, let"s remember what "relative humidity" is. It is known from the school course of physics that this is the ratio of the amount of water contained in the air at a given temperature to the maximum amount of water at a given temperature in the form of vapor. The humidity is measured as a percentage and actually shows how much more moisture is not enough for condensation to begin at a given temperature, i.e., the amount of water contained in the air at a given temperature. е. Conversion of vapor into liquid. Accordingly, the higher the temperature of the air, the more moisture it can retain. The lower the temperature, the faster condensation (vapor turns to water) falls.

Both at home and at work, dry air during air conditioner operation is a real issue.

The temperature of the air decreases as it moves through the air conditioner. The amount of moisture in the air can no longer be retained at the same level. When the cooled air is brought back into the room, it gets heated once more and has a much lower relative humidity. The air in the room is therefore extremely dry. A drainage pipe allows the condensed excess moisture to be released outside. On the walls of homes or office buildings, they are easily noticeable. In essence, we observe the amount of water lost by the cooled air.

Topic	Dry function in an air conditioner: what it is and why it is needed, features and principle of operation
Description	The dry function in an air conditioner helps to reduce humidity levels in the room, making the environment more comfortable and preventing mold growth.
Why it"s Needed	It"s essential for areas with high humidity where traditional cooling may not be enough to create a comfortable living or working space.
Features	This function works by removing moisture from the air while still providing cooling, ensuring a balanced and pleasant indoor climate.
Principle of Operation	The air conditioner"s dry function operates by circulating air through a cooling coil to condense moisture, which is then drained away, leaving the air drier.

Maintaining a cozy and healthful interior atmosphere can be greatly improved by being aware of the dry function on an air conditioner. On hot, muggy days, this feature helps lower the humidity levels in your house, giving the air a cooler, more refreshing feeling.

The dry function operates on a very basic but efficient principle. The air conditioner’s compressor operates at a reduced speed when it is turned on, which enables it to remove moisture from the air without significantly cooling the space. This procedure can also address problems like dampness and musty odors. Mold and mildew are microorganisms that prefer high humidity conditions.

Additionally, utilizing the dry function can help save energy. The air conditioner uses less electricity when it operates at a lower capacity and less work for the compressor than when it runs at maximum power. This reduces the environmental impact of excessive energy consumption in addition to helping to lower your energy bills.

In summary, an air conditioner’s dry function is a useful feature that improves comfort, encourages a healthier interior atmosphere, and aids in energy efficiency. Whether you live in an area with high humidity or you just want to get the most out of your air conditioning system, using this feature can significantly improve the comfort and health of your house.
