Air heating

Air heating systems can make all the difference in keeping your house cozy and warm. Air heating systems, as opposed to conventional radiators or underfloor heating, transfer heat through the air to create a comfortable and uniform temperature throughout your house. Making the best decision for your home can be aided by knowing the ins and outs of air heating, whether you’re building a new home or looking to upgrade your current heating system.

The speed and efficiency with which air heating systems heat your house is one of their main advantages. Air heating systems provide instantaneous heat as soon as they are turned on, eliminating the need to wait for radiators to warm up or for warmth to rise from the floor. As a result, you won’t have to wait around for your house to warm up to enjoy a comfortable and welcoming space.

The adaptability of air heating systems is another benefit. In contrast to radiators or underfloor heating, which may occupy valuable wall or floor space, air heating systems are typically installed in the ceiling or beneath the floor, out of sight. This gives you greater freedom in terms of room arrangement and design in addition to freeing up space in your house.

Technology advancements have made air conditioning systems more energy-efficient than they have ever been. You can simply control the temperature in various rooms of your house by using thermostats and zoning controls, which will make sure that you only heat the areas that you use. In addition to lowering your carbon footprint and lowering your energy costs, air heating systems are an eco-friendly option for your house.

Air heating systems of production premises

Heating of the premises using infrared

Manufacturers are forced to consider all cost factors due to the heightened competition in the home market. The costs of heating production facilities are not the lowest on this list. The proportion of energy carriers in the overall cost structure has significantly increased along with their cost. Selecting a cost-effective solution for heating production facilities fell into the urgent category from the "long-playing" category. Air heating is one of the most practical and affordable solutions to the problem and is frequently considered.

Operating principle

A heat generator and closed routes are used in air heating to distribute heated air masses to production workshops, warehouses, cabins, and other spaces. Naturally, pressure is involved in the supply of heated air. The fan, which is positioned in front of the heat generator in the diagram, is responsible for carrying it. Air is distributed for individual highways through automated distribution systems or mechanical shifts.

Often, the heating systems of industrial premises are presented in the form of mobile devices. Portable thermal guns are characterized by high performance and are able to very quickly warm up any room. All air heating options additionally solve the problem of recirculation of air flows. This positively affects the general sanitary-hygienic state of the premises.

Advantages and disadvantages

There are definite benefits to the air heating method:

  1. The utility coefficient reaches 93%. When organizing heating, it is not required to install intermediate heating devices.
  2. This type of heating systems can be completely integrated with ventilation. This allows you to constantly maintain the optimal microclimate inside production complexes.
  3. Very low inertia level. Immediately after activation of the equipment, the air temperature begins to rise in the room.
  4. High efficiency positively affects the economic indicators of production and a decrease in the cost of production.

Additionally, air heating has the following definite drawbacks:

  1. Constant technical care of the active elements of the system is required. It is quite difficult to modernize already working installations.
  2. So that there are no interruptions with heat supply, a reserve source of power supply is needed.

System design

In order to arrange the air heating system, design documentation must be created. It is best to leave the creation of the plan and the execution of the calculations to knowledgeable experts. It would be ideal if they could put these projects into action practically. Otherwise, it is not excluded that production facilities may have unbalanced temperature conditions or elevated noise levels.

Many issues should be successfully resolved by the organization that plans the heating scheme of industrial premises:

  1. Determine the estimated level of thermal losses in each individual room.
  2. Taking into account unproductive heat expenses, calculate the power of the heat generator.
  3. Calculate the amount of heated air and the estimated temperature regime.
  4. Determine the diameter of the air channels and pressure loss from the negative aerodynamic characteristics of the highway.

The project can be drawn up and then the equipment purchase can start.

Installation of air heating

Warming of manufacturing facilities

It is very simple to carry out installation work by the forces of the enterprise’s employees when there is a clear plan for the locations of the system’s assemblies and units. You can, if you’d like, get in touch with specialist businesses. Priority one when installing independently should be given to the supply’s completeness. Air ducts, shutters, inscriptions, and other standard components are supplied by manufacturers upon request.

Additionally, the following materials are available for purchase:

  • Flexible highways
  • Aluminum tape
  • insulation and mounting tape

Certain areas need to be insulated because doing so helps you avoid condensate formation. To achieve this, pipeline walls are covered with a layer of self-adhesive foil insulation. It may or may not be thicker. The thickest, 3-5 millimeters, are the most in demand.

Flexible or tough highways are established based on the design solution and the geometry of the premises. Using metal or plastic clamps or reinforced adhesive tape, some areas are joined to one another. The execution of this series of steps constitutes the entirety of the installation work:

  • Installing warm air for the highways
  • Installation of camshafts
  • Installation of a heat -generating unit
  • Laying the heat -insulating layer
  • Installation of additional equipment

The warehouse has air conditioning. Utility and production rooms are fully functional heating systems. Her efficiency and high efficiency are her defining traits.

Heating methods of industrial and warehouse premises

Industrial buildings have unique heating requirements due to their large floor plans, tall ceilings, and frequently constrained areas of necessary thermal comfort. Large retail spaces, production spaces, warehouses, hangars, and other similar spaces are not always well suited for water heating, which is typically found in residential buildings. P. Heat must be provided in the lowermost portion of the rooms, up to a height of two to three meters. Owners unintentionally heat 70–80% of the "extra" volume as warm air flows ascend. How can industrial spaces be heated affordably?

Since industrial buildings are hundreds of square meters in size, standard heating systems are both inefficient and prohibitively expensive.

In the article "Air Heating" on our website dedicated to heating and insulating homes, we explore the benefits and options of using air as a heating source. Air heating systems offer an efficient and cost-effective way to keep your home warm and comfortable during the colder months. Whether it"s through forced air systems, such as furnaces, or radiant heating systems, like air heaters, understanding the different types of air heating options available can help you make an informed decision about what"s best for your home. We"ll discuss the pros and cons of various air heating systems, their installation, maintenance, and energy efficiency, providing you with the information you need to keep your home cozy and energy-efficient.

Options for heating spacious non -residential buildings

Large-scale heating is typically accomplished using three primary types of systems:

Water heating refers to radiator-based systems. Their large assortment of heating devices makes them advantageous. However, many property owners are also dissatisfied with the excessive energy consumption, high costs, and irrational use of the space, as well as the significant thermal inertia. Systems are not appropriate for large outlets or warehouses; instead, radiators are mounted on the walls, where racks are conveniently located. Since air and radiant heating are more common, we will go into great detail about how they should be arranged.

The shopping center’s air conditioning system

Air heating of industrial premises

In the 1970s, this technique of heating production space gained popularity. The basic method of operation relies on using heat generators, steam or water high-califiers, or air heating. Collectors bring air into the zones where temperature maintenance is required. Special distribution heads or blinds are installed to distribute air flows. Although this method of heating is far from ideal and has a number of drawbacks, it is nevertheless quite popular.

Central and zonal systems

You can equip individual zones or the entire room with uniform heating, depending on the needs of the building owners. The equipment that brings outside air inside to warm it for use in buildings is known as central air conditioning. The inability to regulate the temperature in different building rooms is the primary disadvantage of this kind of system.

You can establish the ideal temperature regime in every room with zonal heating. This is accomplished by installing a separate heating unit—typically a gas convector—in each room to maintain the desired temperature. Because the zonal system minimizes irrational expenses and only uses as much energy as is required for heating, it is economically advantageous. There’s no need to lay air ducts during installation.

An expert specialist should determine the proper system type and compute the air heating of the production premises. The following elements are considered:

  • thermal losses;
  • necessary temperature regime;
  • the amount of heated air;
  • Power and type of air heater.

Advantages and disadvantages

Fast air heating and the ability to combine heating and ventilation are two significant benefits. The drawback stems from the widely recognized principle of physics: heated air rises to higher temperatures. Under the ceiling, a warmer zone is produced than at the height of human growth. There may be a few degree difference. For instance, the temperature in workshops with ceilings that are 10 meters high at the bottom can reach 16 degrees, and up to 26 degrees in the upper portion of the space. In order to preserve the intended thermal regime, the system needs to run continuously. When buildings are heated in such an inappropriate way, owners search for alternative solutions.

Industrial buildings’ air conditioning systems

Radiant heating – economical systems for large industrial buildings

Installations of "light" and "dark" infrared heaters are made to heat production facilities. As a heat source, liquefied or natural gas is utilized. The suspended radiating panels are mounted in buildings where it is not possible to install gas equipment for whatever reason.

Features of the work of different types of infrared heaters

A specialized burner with a surface temperature as high as 900 degrees is used to burn the gas in "light" heaters. The radiation required is produced by the hot burner. "Dark" heaters, also known as "pipe" heaters depending on the kind of building, are emitters with reflectors that are intended to direct radiant energy into the areas of the building that are of interest. Pipe infrared devices have a much wider range of applications because they emit less intense radiation and heat up to 500 degrees.

Because they are so versatile, suspended radiating panels are utilized in a wide range of commercial, industrial, and storage settings. The intermediate coolant "steam/water" is used by systems. The devices have the ability to heat water to 60-120 degrees and steam to 100-200 degrees. These days, it’s the most practical and affordable method of heating businesses and industrial spaces.

Pros and cons of radiant heating

There are certain unquestionable benefits that set infrared heaters apart:

  • quick heating of the premises (15-20 minutes);
  • the possibility of creating warm zones in unheated rooms;
  • lack of energy losses for heating the "extra" area ";
  • minimum heat loss in systems working without coolant;
  • Savings on maintenance, since you do not need to change filters, check, repair pumps, etc.P.;
  • Comfortable microclimate: the air is not overdried, the floor heats up and serves as a secondary heat source.

Infrared heater installation is not possible:

  • if the height of the ceilings is below 4 m;
  • in industries where radiation affects product quality or technological processes;
  • In the premises of fire categories A, b.

The operation of the infrared heater

Industrial buildings can operate their infrared heating systems more affordably and conveniently than their air systems. Heat zones are created at the height of human growth by radiant heating devices, which also do not dry out the air or contribute to the spread of dust. People feel more comfortable in the rooms because the floor is heated by radiation. However, radiant heating is not appropriate for all buildings, and in those cases, air conditioning will be the best option.

Heating of industrial premises is a necessary condition for the protection of employees" health and equipment safety

Employees of the company are given comfortable working conditions during the colder months thanks to the autonomous heating of the production facilities. Buildings, machinery, and equipment safety all benefit from the temperature regime becoming more normal. Despite the same tasks at hand, heating systems differ technologically. Some people heat industrial spaces with hot water boilers, while others use compact heaters. Think about the particulars of production heating and the efficiency of using different systems.

Requirements for heating industrial premises

Temperature ranges for different types of work

When workers spend more than two hours in production facilities during cold weather, labor protection regulations mandate that the facilities be heated. The only places exempt from this rule are those where frequent visits by people are not required, like warehouses. Furthermore, since the buildings lack heat, being inside them is equivalent to working outside of them. Here, though, it ought to be accommodated by the existence of particular heating mechanisms.

The following hygienic and sanitary standards are mandated by labor protection for heating production facilities:

  • warming up indoors to a comfortable temperature;
  • the ability to adjust the temperature due to the amount of heat released;
  • the inadmissibility of air pollution by harmful gases and unpleasant odors (especially for furnace heating of industrial premises);
  • desirability of combining the heating process with ventilation;
  • ensuring fire and explosion safety;
  • Reliability of the heating system during operation and ease of repair.

The temperature in heated rooms can be lowered during non-working hours, but it can never drop below +5 °C. In addition, production heating needs to have enough power to bring the temperature back to normal by the start of the workday.

Calculation of autonomous heating of the production premises

Even when a production building is still being built, the heating system installation process starts.

The production premises use the general rule that a constant temperature with little variation should be maintained in the workshop, garage, or warehouse when calculating the autonomous heating. In order to do this, a central boiler room is constructed, and industrial buildings’ working areas have heating radiators installed. On the other hand, certain businesses require the establishment of distinct areas with different air temperatures. A computation is performed on the usage of the central heating system in the first scenario and the use of local heaters in the second.

In actuality, the following factors ought to be taken into consideration when calculating the production facilities’ heating system:

  • area and height of the heated building;
  • heat losses through walls and roofs, windows and doors;
  • heat loss in the ventilation system;
  • heat consumption for technological needs;
  • thermal capacity of heating units;
  • rationality of using one or another type of fuel;
  • The conditions for laying pipelines and ducts.

This is used to calculate how much heat energy is required to maintain the ideal temperature. A more precise calculation of heating systems for production facilities is made possible by the use of special computed tables. The heat consumption must be estimated using particular characteristics in the lack of data on the building’s heat engineering properties.

When selecting between different production system types, considerations such as production details, heat engineering calculations, fuel availability and cost should be made, and technical and financial arguments should be supported. The most closely matches the self-sufficient heating of infrared, water, air, and electric systems found in contemporary production facilities.

Infrared heating of industrial premises

In order to create the necessary thermal comfort at workplaces, infrared heating of industrial premises is often used. Infrared (IR) local thermal emitters are installed mainly in the workshops and in warehouses with an area of ​​up to 500 m² and with high ceilings. In each of these devices, the heat generator, heater and heat -rolling surface are structurally combined.

Benefits of infrared heating for commercial spaces:

  • only heating the floor, walls, workshop equipment and directly people working indoors;
  • The air does not heat up, which means that the consumption of thermal energy is reduced;
  • dust does not rise into the air, which is especially important for enterprises of the electronic, food industry and accurate mechanical engineering;
  • The costs of designing and installation of heating are minimized;
  • Infrared heating devices do not take a useful area.

The heated zone is directly above where radiant energy is produced.

There are two types of infrared heaters: portable and stationary. They can be installed on the floor, wall, or ceiling, depending on the location. If it becomes imperative to impact specific tasks, employ focused infrared radiation with compact wall heaters. However, the production room’s ceiling can be used to mount the film infrared heating system, which will ensure even heating throughout. Warm floors that rely on panels with integrated infrared heaters are also frequently installed, however this type of system uses more electricity.

In addition, infrared gas heating is utilized in businesses. Natural gas, which is less expensive than electricity, is used as fuel in these heating devices. The efficiency of gas infrared emitters is their primary benefit.

There are various types of enlargements available for infrared gas heating systems in industrial buildings.

  • high -intensity (light) with the heat transfer temperature 800–1200 ° C;
  • low -intensity (dark) with a temperature of 100–550 ° C;
  • low -temperature with a temperature of 25-50 ° C).

The inability to use industrial infrared heaters in spaces with ceilings lower than 4 meters is a limitation on their use.

Water heating of industrial premises

Diagram of a boiler room heater used in production

If the business plans to use a water heating system, it will need to install heating radiators in production facilities, lay a pipeline system, and construct a special boiler room for its device. Apart from the primary components, the system also has mechanisms to guarantee functionality, like manometers and shut-off valves. It takes specialized staff to maintain a production site’s water heating system on a continuous basis.

Based on its mechanism, production facilities’ water heating can be:

  • one -pipe – regulation of water temperature is impossible here, since all heating radiators for industrial premises are installed sequentially;
  • two -pipe – temperature regulation is permissible and is carried out using thermostats on radiators installed in parallel.

Heating boilers are heat-generating units. They are classified as follows based on the fuel type used: gas, liquid, solid, electric, and combined. Small industrial buildings can be heated with stoves that have a water circuit.

Select the boiler type that best suits the requirements and resources of a specific business. One incentive to buy a gas boiler, for instance, will be the ability to connect to the gas line. When there is no natural gas available, they favor diesel or better solid fuel units. Boilers for electric heating are frequently utilized in industrial settings, but only in smaller structures.

It is advisable to have an alternate heating unit at the business because accidents or malfunctions in the gas and power supply systems can happen in the middle of the heating season.

Although combined boilers are far more expensive, they come with multiple burner types, including G Azov-Drying, gas-diesel, and even gas-diesel-electrical.

Air heating of industrial premises

The production workshop’s area is warmly distributed with heat thanks to the air duct system.

Every industrial facility has the option of using its air heating system as the primary or backup. In any event, installing air conditioning in a workshop is less expensive than installing water because heating industrial spaces doesn’t require the installation of costly boilers, pipelines, or radiators.

Benefits of the production facilities’ air conditioning system:

  • saving the area of the working area;
  • energy -efficient resource consumption;
  • simultaneous heating and air purification;
  • the uniformity of the heating of the room;
  • safety for the well -being of workers;
  • Lack of risk of leaks and freezing of the system.

The production area’s air heating could be:

  • central – with a single heating unit and an extensive network of air ducts, through which heated air spreads through the territory of the workshop;
  • local -air heaters (air-heating units, heat guns, airborne curtains) are located directly in the room.

A recuperator, which uses some of the heat from the interior air to warm outside air, is used in the centralized air heating system to lower energy costs. Local systems simply heat the air inside; they don’t bring in outside air to aid in recovery. Wall-heat heaters are useful for drying any materials and surfaces as well as heating specific tasks.

By reducing capital costs significantly, enterprise managers are able to save money on air heating of production premises.

Especially in colder climates, air heating systems provide a practical and effective way to maintain a warm and cozy home environment. These systems ensure that every room in your house stays warm and comfortable throughout the winter by using either forced air or radiant heat.

Weighing the benefits and drawbacks of an air heating system for your house is important. Even though they can be reasonably simple to install and reasonably priced, air heating systems might not be the best choice for every house. Before choosing a choice, consider various aspects like the local climate, the size of your house, and your financial situation.

All things considered, air heating systems offer a dependable and efficient way to maintain a warm and cozy home. For maximum performance and energy efficiency, whether you go with a forced air system or radiant heat, correct installation and maintenance are essential. You can enjoy a warm and inviting home all winter long if you have the proper system in place.
