Which is better – supply ventilation or air conditioning air conditioning

Ensuring adequate ventilation and temperature control is essential for establishing a comfortable living space. Air conditioning units and supply ventilation systems are two typical solutions that spring to mind when discussing heating and insulation for your home. Both are important for preserving comfort and indoor air quality, but they function differently and have unique advantages. To assist you in making a decision for your home, let’s compare supply ventilation and air conditioning in more detail.

The way supply ventilation systems operate is by drawing in fresh outdoor air and expelling old indoor air at the same time. These systems are made to continuously supply fresh air, which lowers humidity, allergens, and pollutants to improve indoor air quality. Supply ventilation ensures that indoor air is exchanged with outdoor air, preventing the accumulation of moisture and pollutants and promoting a healthier living environment for residents.

However, the main purpose of air conditioning units is to control the temperature inside by eliminating heat from the air. Their primary purpose is to cool the interior during hot weather, but they can also somewhat improve indoor air quality by removing dust and allergens. Refrigerant cycles are used by air conditioning systems to move heat from the inside to the outside, enabling residents to keep their temperature comfortable no matter what the weather is outside.

There are a number of considerations to weigh when choosing between supply ventilation and air conditioning, including climate, requirements for indoor air quality, and personal preferences. For the purpose of minimizing energy consumption and maintaining a comfortable indoor environment, supply ventilation may be adequate in areas with mild climates and good outdoor air quality. To accomplish both temperature control and air purification, air conditioning might be required in regions with extremely high temperatures or high concentrations of outdoor pollutants.

When deciding between supply ventilation and air conditioning, one should also take into account the cost of installation, operation, and maintenance. In general, supply ventilation systems use less energy to run than air conditioners, which can eventually result in lower utility costs. A supply ventilation system’s initial cost could be greater, though, particularly if new ductwork needs to be installed or existing ducts need to be modified.

In summary, supply ventilation and air conditioning are critical components of a cozy and healthful interior atmosphere. Budgetary constraints, indoor air quality requirements, and climate all play a role in which option is best. Homeowners can choose a heating, ventilation, and air conditioning system that best suits their needs by weighing the advantages and disadvantages of each option.

Types of supply air conditioners

Every air conditioner that has an external air fence operates based on this principle:

1. When the user converts the split system into cooling mode, the function of the supply ventilation is turned on.
2. The outdoor supply flap opens through the duct paved from the street to the room through the outer wall.
3. The fan picks out street air and drives through the filter. After cleaning, there is a fit to the main air flow from the room, cooling and further processing – moisturizing, drainage, ionization (in the presence of these functions).

Vital elucidation. The addition of an external tributary is implemented differently in air conditioners made by different manufacturers. In the section below, we will examine each kind of home cooler and analyze this problem.

The following types of supply air conditioners are available in the online stores selling climate-controlled household appliances:

• classic split systems with internal blocks of wall, floor (column) and ceiling installation;
• window, mobile and floor-mounted cooler without an external unit;
• channel air conditioning systems.

Give each of these units’ device and operating principle a brief thought.

Split systems with an influx of fresh air

We would like to investigate the tributary supply in "Splits" using the Hitachi Ras-10JH4/RAC-10JH4 climate installation from Japan as an example. The unit is priced at 43,500 rubles. (675. e.), the technical attributes appear as follows:

• Heating power – 3.4, cooling – 2.6 kW, the service area – 25 m²;
• compressor type – inverter;
• The total amount of processed air is 510 m³/h, the supply – a maximum of 25 m³/h;
• Additional functions-humidifier, ionizer, filter-duster ultraviolet and ordinary.

The independent supply and exhaust fans on the air conditioner, which can be turned on manually or automatically, are its unique feature. As a result, an air pipe that exits the internal module and heads toward the street has a diameter of roughly 40 mm.

In automatic mode, the split system operates as follows:

1. A special sensor measures the degree of air pollution of the room. Reacts to a lack of oxygen, various suspended particles, cigarette smoke. Когда концентрация вредных веществ достигает установленного порога (можно настраивать), датчик запускает вентилятор.
2. The divert of contaminated air masses begins onto the street, lasts 20 minutes. Then the injection mode is turned on, the fan takes the air from the outside and supplies to the room through a special hole or together with the main stream, as shown in the diagram.
3. Air fence/ejection operates regardless of the air conditioning mode.

To be clear. The influx is blended with the main stream when cooling or heating is activated. The fan impeller forces supply air through a unique aperture in the inner unit when the air conditioner is off.

By pushing the appropriate button on the remote control panel, the user can manually turn on the ventilation. There is just one requirement: the outside temperature must be between 3 and 30 °C in order for the damper to open and the fan to turn on. The protection against condensate and the use of electricity for supply air heating or cooling has been achieved by the split system in this way. Watch the video for a quick rundown of the equipment from a different well-known Daikin brand:

The other two -block air conditioners with ventilation are also set up to work in a similar manner. The majority of models only come with a tributary, which is automatically included and does not have cooling (when heated). There is no ventilation regime in the cassette modules that are positioned in the middle of the building.

Monoblock units

Here, we’ll examine the example once more: a wall-mounted Napal air conditioner with Climer SX-25 air flow. Actually, this entire climatic station is furnished with the following components:

• evaporator, capacitor and compressor of the refrigeration unit;
• a recuperator for the transfer of heat from exhaust air to the tributary;
• Fancoil connected to a water heating system of a private house or apartment.

Citation. These types of climate conditions are known as central air conditioning. The Climer SX series monoblocks are priced starting at 68200 rubles. (1050 U.E.).

As seen in the picture, the filter system, fans, and the other equipment are all integrated into a single case that is hung from the wall above the floor. The rear panel has two exit points: a supply and an exhaust pipe.

The ability of this air conditioner to:

1. Clean and moisturize air flows before serving.
2. Remove contaminated air from the room and simultaneously escalate fresh.
3. Save electricity. Streams exchange heat energy in the river (in winter – warm, in summer – cold).
4. Work in the air pump mode, while the street temperature allows (up to +5 degrees).
5. Heat the room using the built -in fan coil to home heating.

As you can see, one of the many uses for a stationary monoblock climater is supply ventilation. The SX-25 model’s air conditioning system covers a space of up to 25 m² and has a 400 m³/h capacity; the influx volume is 30 m³/h. The power is 2.78 kW of cold heat, or 2.64 kW of "Split-Old" power.

The supply and exhaust regime operates continuously in the air conditioner (switching on automatically) or at the user’s request. Through one 160 mm-diameter pipe, a fan absorbs the air, which is then released through the second 150 mm-diameter pipe.

Of course, there are other portable air conditioners with street air fence that are simpler and less expensive. These are the models (higher in the photo) that have two air ducts that need to be visible. The purpose of the second pipe is only an influx. The interesting thing is that no installation of this kind supplies more air than 30 m³/h.

Channel air conditioning systems

You can refer to any channel air conditioning as a supply. Because these coolers are integrated into the rectangular ducts and lack facing panels, they are also known as innocent coolers. Any air that has come to him through the ventilation room, including the influx, will be processed by such air conditioning.

How does it operate in a rural home or apartment?

1. A forced ventilation system with channels hidden under the ceiling is arranged in the dwelling.
2. The internal air conditioning unit is mounted on the air duct after the filter element and fan. The external module is placed on the facade of the building and is connected to the channel freon highways.
3. Further, the main thing: partial recirculation is organized. This means that fresh and internal polluted air in the same or different proportions – 50/50, 70/30 and so on (determined by calculation) is supplied to the air conditioning.
4. After cleaning and cooling, the air masses are sent to the premises through the supply grilles.

Keep in mind that we are discussing equipment designed especially to cool air flows. There are numerous other channel-type ducts in addition to them, including recuperators, heaters, cleaners, and whole air processing complexes.

Pros and cons of air conditioners with ventilation

Let’s begin by discussing some favorable aspects. Utilizing a split system or a monoblock with a tributary enables you to remove part of the contaminated air and refresh the room’s air. The combination of a channel unit, fan, and air duct network is the most effective solution in this aspect. The video is followed by an image of the apartment’s implementation strategy.

A supply ventilation air conditioner is ideal for kid’s and sleeping rooms, as well as spaces where a complete air exchange cannot be guaranteed. Purchasing a two-in-one cooler allows you to accomplish two goals at once: arrange air conditioning and update (up to a point).

Low performance is the primary drawback of such equipment—rather than even its high cost. Studying our guide to determine the apartment’s ventilation requirements will help you realize that a single dwelling requires more than 25–30 cubic meters of fresh air per hour. A minimum of 67 m³/h is required for a 25-square-meter room.

A crucial aspect. High performance on the influx can only be achieved by channel systems that have air conditioning units integrated into them. Although it is the most costly option, this is the best forced mechanical ventilation system.

The remaining drawbacks are listed as follows:

1. In second place is the price of equipment. Comparative calculation: regular "split" Haier HSU-09HTL103/R2 costs 285. e. plus a wall supply valve 25 in. e., Total – 310 at. e. The supply unit of the same brand Haier HSU-09HNF03 will cost 550. e. The wall will have to be drilled in any case.
2. Update the air environment is necessary in all residential premises. Buy and put in each room air conditioning with ventilation-not an option, a multi-split system will cost even more.
3. The cooler gives fresh air while the fan works. If the light is disconnected or the automation of the unit works, the update of the medium will stop.
4. A permanent fan does not mean continuous noise.

Participants’ opinions of mobile supply air conditioners and monoblock complexes are not particularly positive. While the latter are happening and extremely noisy, the former have issues with electronics.

It can be difficult to decide between supply ventilation and air conditioning when it comes to maintaining a comfortable home. Each system has advantages and disadvantages, and in the end, the choice you make will rely on your unique requirements and preferences.

The way supply ventilation operates is by drawing in fresh outdoor air and expelling old indoor air. This can lessen allergens and pollutants in the air, which can enhance indoor air quality. Supply ventilation systems can also aid in controlling humidity levels, which is crucial for comfort and the avoidance of mold growth.

However, air conditioning systems are perfect for hot, humid climates because they cool and dehumidify the air. They can instantly relieve the intense summer heat by rapidly lowering the interior temperature. Air conditioning systems, however, usually circulate air inside, so they might not always offer the same amount of ventilation as supply systems.

A number of factors, including climate, financial constraints, and personal preferences, must be taken into account when selecting between supply ventilation and air conditioning. For year-round comfort in your home, supply ventilation might be adequate in moderate climates with low humidity levels. To maintain a comfortable indoor environment, air conditioning might be required in warmer and more humid climates.

The optimal option for your house ultimately depends on your particular situation. To get the ideal mix of comfort and indoor air quality, some homeowners might decide to use both supply ventilation and air conditioning. It’s critical to speak with HVAC experts to evaluate your requirements and choose the best system for your house.

In the debate over heating and insulation for your home, the main thesis revolves around finding the most effective and efficient method to maintain comfortable indoor temperatures while minimizing energy consumption and costs. Both supply ventilation and air conditioning offer distinct advantages and drawbacks. Supply ventilation ensures fresh air circulation, reducing indoor pollutants and maintaining air quality, but it may not effectively control temperature. On the other hand, air conditioning provides precise temperature control but may recirculate indoor air, potentially leading to stale conditions. The choice ultimately depends on factors like climate, budget, and personal preferences, highlighting the need for careful consideration and possibly a combination of both systems to achieve optimal comfort and energy efficiency.
