Organizing a production process is a multifaceted task in which all factors must be taken into account. In addition to equipment and qualified workers, attention should be paid to Special attention maintaining optimal room temperature. To do this, you need to develop systems and heating schemes for workshops with your own hands: welding, carpentry, production.
Selecting heating according to room characteristics
Before you make the heating of the workshop with your own hands, you need to find out a few important characteristics. First of all, the optimal temperature in the room. The choice of heating system directly depends on this.
When drawing up a heating scheme carpentry shop or others production areas the following parameters need to be taken into account:
- Ceiling area and height. If the distance from the floor to the roof is more than 3 meters, then convection (water, air) systems will be ineffective. This is due to the large volume of the room;
- Thermal insulation of walls and roof. Heat loss buildings are the first thing to consider when choosing. The heating system for the workshop must not only be efficient, but also economical. In this case, it is best to use zonal heat sources. They will maintain a comfortable temperature level in a certain area of the room;
- Technological requirements for optimal temperature in the workshop. For example, the heating of a woodworking shop must maintain air heating at a constant level. Otherwise, it will affect the quality of the products. If the raw material is metal, then a comfortable temperature is needed only for workers.
To carry out this analysis, you will need to study the advantages and disadvantages of each type of heating. Let's consider the most efficient heating of a production workshop, which differs depending on the design and components used.
Air heating of the workshop
For large rooms with high temperature requirements, it is recommended to use air heating in the workshop. This system is an extensive network of air channels through which flows of hot air move. It is heated using a special climate control unit or gas boiler.
Such do-it-yourself workshop heating systems and schemes are applicable for welding, carpentry, and industrial premises. Main structural elements of this system are:
- Outside air intake device. It includes fans and cleaning filters;
- Next, the air masses enter the heating zone through the channels.. This can be electrical appliances (spiral element) or gas installation with air heat exchanger;
- Air masses with high temperatures move through channels that distribute heat to individual production rooms. To regulate the heating temperature level, a throttle valve is installed in each outlet pipe.
Such a workshop air heating system has a number of significant advantages over the standard one. The main one is optimal heating of the room. Properly positioned air ducts can have guide elements that focus air flow to the desired area of the workshop.
Also, with the additional installation of an air conditioner, the same system can be used as a cooling system. However, such a workshop heating scheme is quite complex in terms of design. Before self-installation you need to calculate the power of the fans, the shape and cross-section of the air ducts. Therefore, for the installation of air heating in a production workshop, it is recommended to use the services of specialized companies.
Water heating of the workshop
The use of traditional water heating is relevant for small industries whose workshop area does not exceed 250 m². It is necessary to constantly maintain the air temperature at the optimal level throughout the entire volume of the room. Woodworking shops are often heated using water.
This is due to wood waste from production. For their disposal, a long-burning solid fuel boiler is installed. This scheme of work allows you to not only quickly but also effectively get rid of wood waste. They are subsequently used as fuel.
However, this heating organization scheme has a number of nuances:
- In order for the heating efficiency of the production workshop to be maximum, it is necessary to significantly increase the area heating devices. Pipes are used for this large diameter, which are welded together into registers;
- Inertia. It takes quite a long time to heat the air in the workshop from the coolant;
- The inability to quickly change the water temperature in the pipes.
However, along with this, when installing water heating in a welding shop, a heated floor system can be used. This scheme will help reduce the required area of heating devices. At the same time, the inertia of the system will decrease - the air in the workshop will heat up faster.
During heating design, it is possible to provide for the organization of hot water supply, which is important for many production processes. To do this, you need to purchase (or make) a heat exchange tank to heat the workshop with your own hands.
In it, the coolant energy will be transferred through the coil to the water. This will make it possible to use hot water not only for domestic needs, but also for production processes.
In addition to solid fuel boilers, you can install other types heating equipment:
- Gas boilers. Economically effective if there is no cheap solid fuel;
- Electric heaters. It is preferable not to use them, since energy costs will be high;
- Boilers running on liquid fuel - diesel or waste machine oil. Installed if there are no gas lines. They are economical, but inconvenient because they require special containers for storing fuel.
To use water heating circuits for a workshop, you need to correctly calculate the power of the heating installation.
The standard ratio of 1 kW of released thermal energy per 10 m² of area is only relevant for a workshop whose ceiling height does not exceed 3 meters. If they are higher, then each additional meter is +10% to the boiler power.
Infrared heating of the workshop
The operating principle of infrared heaters is to heat surfaces due to the effects of infrared radiation. If the heating system of the welding shop is designed for spot heating certain areas, then it is best to use these devices. Effective heating with infrared heaters for workshops should begin with the selection of heating elements. Currently, two methods of generating IR radiation are used.
Carbon heaters
Its design consists of a bulb, inside of which there is a carbon spiral, and a reflective element. When current passes through the heating element, it glows due to high electrical resistance. As a result, IR radiation is released.
To focus thermal energy, a reflector made of stainless iron or aluminum is provided.
IR electric heaters can be used as additional heating in a carpentry shop. They are mounted above those work areas where a stable temperature regime is required. The advantages of electric infrared heaters include:
- Easy installation;
- The ability to regulate the heating temperature by changing the supplied current power;
- Small overall dimensions.
However, due to high energy consumption, heating with electric infrared heaters for workshops is rare. Instead they are mounted gas models.
Gas IR heaters
For large production workshops where zonal heating is required, it is recommended to use gas models of infrared heaters. Their operating principle is based on the so-called flameless combustion of a mixture of gas and air on a ceramic surface. As a result, IR radiation is formed, which is focused by the reflector.
For efficient heating of workshops with infrared heaters, ceiling models of heaters are often used. It is important to correctly calculate the mounting height and required power. The heating area and temperature conditions in this part of the workshop will depend on these parameters.
They are used as a heating system for a welding shop, where a comfortable temperature is needed only to ensure normal conditions for the working personnel. However, when planning this type of heating, you need to take into account a number of nuances:
- An infrared heating system for a workshop cannot be used if the air in the entire room needs to be heated. Heaters are designed for local impact;
- To minimize costs, you should use only natural gas from the mains. In addition to the additional purchase of exchange containers, a liquefied cylinder is inconvenient due to the periodic connection procedure.
But despite these disadvantages, the use of infrared heating for woodworking shops and other areas of industry remains the best option. However, for installation gas heating The workshop itself only needs to carry out a number of coordination activities with the gas service in order to obtain all permits.
How to choose the right heating system for a particular workshop? It is necessary to take into account its operational parameters, the cost of purchasing equipment and the price of energy. Remember that the cost of production will depend on the heating efficiency of any production workshop.
If you need economical option organizing the heating of the carpentry shop - you can see in the video non-standard methods heating air using sawdust and wood shavings.
Production facilities, workshops, warehouses, due to their spacious dimensions and taking into account climatic conditions Russia often needs to resolve such an urgent issue as optimal heating. The word “optimal” means the price/reliability/comfort ratio that is suitable for a particular industrial building.
This is what we will talk about in our article.
In general, creating a heating scheme production premises- quite a difficult task. This is due to the fact that each individual production facility is built for specific technological processes, and has very large dimensions and height.
Plus, the equipment used in production sometimes complicates the laying of pipes for ventilation or heating. But despite this, heating industrial buildings – important function, which is impossible to do without.
And that's why:
- a well-thought-out heating system ensures comfortable conditions labor for employees and directly affects their performance;
- it protects the equipment from overcooling, which can cause breakdowns, which in turn will lead to cash costs for repairs;
- Warehouses must also have an appropriate microclimate so that the goods produced retain their original appearance.
Note!
By choosing a simple, but at the same time reliable heating system, you will reduce the cost of its repair and maintenance.
Plus, much fewer employees will be required to control it.
Choosing a heating system for industrial premises
For heating industrial buildings, central heating systems (water or air) are most often used, but in some cases it is more rational to use local heaters.
But in any case, when choosing a production heating system, you need to rely on the following criteria:
- Area and height of the room;
- The amount of heat energy needed to maintain the optimal temperature;
- The ease of maintenance of heating equipment, as well as its suitability for repair.
Now let's try to figure out the positive and negative sides, which the above-mentioned types of heating of industrial premises have.
Central water heating
The source of the heat resource is a central heating system or a local boiler house. Consists of water heating from the boiler, (radiators or convectors) and pipeline. The liquid heated in the boiler is transferred to the pipes, giving off heat to the heating devices.
Water heating of industrial buildings can be:
- Single-pipe - here it is impossible to regulate the water temperature.
- Two-pipe - here temperature control is possible and is carried out thanks to thermostats and radiators installed in parallel.
As for the central element of the water system (that is, the boiler), it can be:
- gas;
- liquid fuel;
- solid fuel;
- electric;
- combined.
You need to choose based on the possibilities. For example, if it is possible to connect to a gas main, a gas boiler would be a good option. But please note that the price is this type fuel consumption increases every year. Plus, there may be interruptions in the central gas supply system, which will not benefit the production enterprise.
Requires a separate safe room and fuel storage tank. In addition, you will have to regularly replenish fuel reserves, which means taking care of transportation and unloading - additional costs of money, labor and time.
Solid fuel boilers They are unlikely to be suitable for heating industrial premises, except perhaps small ones. Operating and maintaining a solid fuel unit is a rather labor-intensive process (loading fuel, regularly cleaning the firebox and chimney from ash).
True, at present there are automated solid fuel models into which you do not need to load fuel with your own hands; a special one has been developed for this automatic system fence Also, automated models allow you to set the desired temperature.
However, you still have to take care of the firebox. The fuel used here is pellets, sawdust, wood chips, and, if placed manually, also firewood. Although this type of boiler requires labor-intensive operation, it is the most inexpensive.
Electric boilers are also not the best option for large industrial enterprises, since the energy consumed costs a pretty penny. But heating a production space of 70 square meters using this method is quite acceptable. However, do not forget that in our country, periodic power outages for several hours have long been a common occurrence.
As for combination boilers, they can be called truly universal units. If you have chosen a water heating system and want to get efficient and uninterrupted heating of your production as a result, then take a closer look at this option.
Although a combination boiler costs several times more than previous units, it provides a unique opportunity - practically not to depend on external problems (interruptions in the centralized heating system, gas supply and electricity supply). Such units are equipped with two or more burners, for various types fuel.
Built-in types of burners are the main parameter for dividing combined boilers into subgroups:
- Gas-wood heating boiler– you don’t have to worry about gas supply interruptions and fuel price increases;
- Gas-diesel– will provide high heating power and comfort in a large area;
- Gas-diesel-wood– has expanded functionality, but you have to pay for it with lower efficiency and low power;
- Gas-diesel-electricity– a very effective option;
- Gas-diesel-wood-electricity- an improved unit. It can be said that it provides complete independence from possible external problems.
Everything is clear with boilers, now let's see whether water heating in production fits the selection criteria that we initially outlined. Here it’s worth mentioning right away that the heat capacity of water, compared to the heat capacity of the same air, is several thousand times greater (at the usual temperatures of air (70°C) and water (80°C) in the heating system).
In this case, the water consumption for the same room will be thousands of times less than the air consumption. This means that fewer connecting communications will be required, which is certainly a big plus, given the design of industrial premises.
Note!
A water heating system allows you to control the temperature: for example, you can work time install standby heating for production (+10°C), and set a more comfortable temperature during working hours.
Air heating
This type is the very first artificial heating of premises. So air heating systems have proven their effectiveness for quite some time now. for a long time and, it should be noted, are in constant demand.
All this thanks to the following positive aspects:
- Air heating assumes the absence of radiators and pipes, instead of which air ducts are installed.
- Air heating shows a higher level of efficiency compared to the same water heating system.
- Air in in this case heats up evenly throughout the entire volume and height of the room.
- The air heating system can be combined with the system supply ventilation and conditioning, which allows you to get fresh air instead of the heated one.
- It is impossible not to mention regular changes and air purification, which has a beneficial effect on the well-being and performance of employees.
In order to save money, it is better to choose combined air industrial heating, which consists of natural and mechanical air circulation. What does it mean?
The word “natural” means the intake of already warm air from the environment (warm air is available everywhere, even when it is -20°C outside). Mechanical induction is when the duct takes cold air from the environment, heats it and delivers it into the room.
For heating a large area air systems heating industrial premises is perhaps the most rational option. And in some cases, for example, at chemical plants, air heating is the only permitted type of heating.
Infrared heating
How to heat an industrial premises without resorting to traditional methods? Using modern infrared heaters. They work on the following principle: emitters generate radiant energy above the heated area and transfer heat to objects, which in turn heats the air.
Information! The functionality of infrared heaters can be compared to the Sun, which also uses infrared waves to heat the earth's surface, and as a result of heat exchange from the surface, the air is heated.
This principle of operation eliminates the accumulation of heated air under the ceiling and, as a result, large temperature changes, which is very attractive for heating industrial enterprises, since most of them have high ceilings.
IR heaters are divided into the following types according to their installation location:
- ceiling;
- floor;
- wall;
- portable floor.
By type of waves emitted:
- shortwave;
- medium wave or light (their operating temperature is 800°C, so they emit soft light during operation);
- long-wavelength or dark (they do not emit light even with their operating temperature 300-400°C).
By type of energy consumed:
- electrical;
- gas;
- diesel
Gas and diesel infrared systems more profitable and their efficiency is 85-92%. However, they burn oxygen and change the humidity in the air.
By type of heating element:
- Halogen– the only drawback is that if dropped or subjected to a strong impact, the vacuum tube may break;
- Carbon- basic a heating element made of carbon fiber and placed in a glass tube. The biggest advantage compared to other IR devices is lower energy consumption (about 2.5 times). If dropped or subjected to a strong impact, the quartz tube may break.
- Tenovye;
- Ceramic– the heating element is made of ceramic tiles assembled into one reflector.
The principle of operation is the flameless combustion of the gas-air mixture inside ceramic tiles, as a result of which it heats up and transfers heat to surrounding surfaces, objects, and people.
IR heaters are most often used for heating:
- industrial premises;
- shopping and sports facilities;
- warehouses;
- workshops;
- factories;
- greenhouses, greenhouses;
- livestock farms;
- private and apartment buildings.
Advantages of infrared heating:
- First of all, it should be noted that IR heaters are the only type of devices that allow for zone or spot heating. Thus, in different parts production premises can be maintained at different temperatures. Zone heating can be used to heat work areas, parts on a conveyor belt, car engines, young animals on livestock farms, etc.
- As mentioned above, IR heaters heat surfaces, objects and people, but do not affect the air itself. It turns out that there is no circulation of air masses, which means there is no loss of heat and drafts and, as a result, fewer colds and allergic reactions.
- The low inertia of infrared heaters allows you to feel the effect of their action immediately after starting, without preheating the room.
- Infrared heating is very economical, due to its high efficiency and low energy consumption (up to 45% less energy than traditional ways). There is probably no need to explain that this significantly reduces the financial costs of the enterprise and quickly recoups all investments in infrared heating facilities.
- IR heaters are durable, lightweight, take up little space, and are easy to install (each product comes with detailed instructions installation) and they require virtually no maintenance during operation.
- Infrared heaters are the only type of heating devices that can provide effective local heating (that is, without resorting to centralized heating systems).
Finally
Finally, I would like to suggest that you familiarize yourself with the photo table, which shows the specific heating characteristics of industrial buildings.
We examined the main types of heating of industrial premises. Which one will be the most optimal in your case is up to you to decide. And we hope that this article was useful to you. You will find additional information on this topic in specially selected video material.
Expert opinion
Fedorov Maxim Olegovich
Production facilities differ significantly from residential apartments their sizes and volumes. This is the fundamental difference between industrial ventilation systems and domestic systems. Options for heating spacious non-residential buildings exclude the use of convection methods, which are quite effective for heating housing.
The large size of production workshops, the complexity of the configuration, the presence of many devices, units or machines that allocate space thermal energy, will disrupt the convection process. It is based on the natural process of rising warm layers of air; the circulation of such flows does not tolerate even small interventions. Any draft, hot air from an electric motor or machine, will direct the flow in the other direction. In industrial workshops, warehouses There are large technological openings that can stop the operation of heating systems of low power and stability.
In addition, convection methods do not provide uniform heating of the air, which is important for industrial premises. Large areas require the same air temperature in all points of the room, otherwise there will be difficulties for the work of people and the flow of production processes. Therefore, for industrial premises specific heating methods are required, capable of providing the correct microclimate, appropriate.
Industrial heating systems
The most preferred methods of heating industrial premises include:
-
infrared
-
centralized
-
zonal
Centralized systems
Centralized systems are created to ensure maximum uniform heating of all areas of the workshop. This can be important when there are no specific workplaces or the need for constant movement of people throughout the entire workshop area.
Zone systems
Zonal heating systems create areas with a comfortable microclimate in workplaces without completely covering the workshop area. This option makes it possible to save money by not wasting resources and thermal energy on ballast heating of unused or unvisited areas of the workshop. At the same time, the technological process must not be disrupted; the air temperature must meet the technological requirements.

Important! It should immediately be noted that heating with electricity as the main method of heating practically not used due to its high cost.
Electric heat guns or air heaters are used as temporary or local heat sources. For example, to carry out repair work in an unheated room, install heat gun, which makes it possible repair team work in comfortable conditions that allow you to obtain the required quality of work. Electric heaters as temporary heat sources are the most popular, as they do not require coolant. They only need to be connected to the network, after which they immediately begin to generate thermal energy on their own. Wherein, The serviced areas are quite small.

Air heating of industrial buildings is the most attractive type of heating.
It allows you to heat large rooms, regardless of their configuration. Distribution air flow occurs in a controlled manner, the temperature and air composition are flexibly regulated. The operating principle is heating supply air with help gas burners, electric or water heaters. Hot air is transported to the production premises using a fan and duct system and released at the most convenient points to ensure maximum heating uniformity. Air heating systems have high maintainability, they are safe and allow you to fully ensure the microclimate in production premises.

Infrared heating - one of the newest, which appeared relatively recently, heating methods production premises. Its essence is to use infrared rays to heat all surfaces located in the path of the rays.
Typically the panels are located under the ceiling, radiating from top to bottom. This heats up the floor, various objects, and to some extent the walls.

Important! This is the peculiarity of the method - It is not the air that is heated, but the objects located in the room.
For more efficient distribution of IR rays, the panels are equipped with reflectors that direct the flow of rays in the desired direction. The method of heating with infrared rays is effective and economical, but is dependent on the availability of electricity.
Advantages and disadvantages

Designing air heating is not an easy task. To solve it, it is necessary to find out a number of factors, the independent determination of which may be difficult. RSV company specialists can make a preliminary one for you free of charge premises based on GREERS equipment.
The choice of one or another type of heating system is made by comparing the climatic conditions of the region, the size of the building, the height of the ceilings, the features of the proposed technological process, and the location of workplaces. In addition, when choosing, they are guided by the cost-effectiveness of the heating method and the possibility of using it without extra costs.
The system is calculated by determining heat losses and selecting equipment that matches them in terms of power. To eliminate the possibility of errors SNiP must be used, which sets out all the requirements for heating systems and gives the coefficients necessary for calculations.

Important! Installation work are manufactured in strict accordance with the design and SNiP requirements.
Air ducts are an important element of the system, which provide transportation of gas-air mixtures. They are installed in each building or room according to an individual scheme. The size, cross-section, and shape of the air ducts play an important role during installation, since to connect the fan, adapters are needed that connect the inlet or outlet pipe of the device to the air duct system. Without high-quality adapters, it will not be possible to create a tight and efficient connection.

In cold weather conditions heating system production premises provide the company's employees with comfortable working conditions. Normalization temperature regime It also has a beneficial effect on the safety of buildings, machines and equipment. Heating systems, although they have the same task, have technological differences. Some use hot water boilers to heat industrial premises, while others use compact heaters. Let's consider the specifics industrial heating and the effectiveness of using various systems.
Requirements for heating industrial premises
At low temperatures Heating of production premises, as required by labor protection, must be carried out in cases where the time workers stay there exceeds 2 hours. The only exceptions are premises in which permanent presence of people is not necessary (for example, rarely visited warehouses). Also, structures are not heated, being inside of which is equivalent to carrying out work outside the building. However, even here it is necessary to provide for the presence of special devices for heating workers.
Occupational safety imposes a number of sanitary and hygienic requirements for heating industrial premises:
- heating indoor air to a comfortable temperature;
- the ability to regulate the temperature due to the amount of heat generated;
- inadmissibility of air pollution with harmful gases and unpleasant odors(especially for stove heating production premises);
- the desirability of combining the heating process with ventilation;
- ensuring fire and explosion safety;
- reliability of the heating system during operation and ease of repair.
Heating calculation
To carry out a thermal calculation, before planning any industrial heating, you need to use the standard method.
Qt (kW/hour) =V*∆T *K/860
The heat loss coefficient, which is included in the calculation of the heating system for industrial premises, varies depending on the type of building and the level of its thermal insulation. The less thermal insulation, the higher the coefficient value.
Steam heating of industrial buildings
Heating the production premises using steam allows you to maintain a high temperature of the environment (up to 100 degrees). When organizing the heating process, you do not need to take into account the number of floors. You can bring the temperature to the required value in short time. This applies to both heating and cooling. All equipment, including communications, does not take up much space.
The steam heating method is optimal if the production premises need to be heated or reduced in temperature periodically. The method is more effective than the water method.
The following disadvantages are identified:
- there is a lot of noise during operation;
- it is difficult to regulate steam flow;
- The steam method is not recommended for use in rooms with aerosols, flammable gases, or heavy dust.
Water heating of industrial facilities
Water heating is appropriate if you have your own boiler room nearby or if there is a central water supply. The main component in this case will be an industrial heating boiler, which can run on gas, electricity or solid fuel.
Water will be supplied under high pressure and temperature. Usually, it cannot be used to efficiently heat large workshops, which is why the method is called “on-duty”. But there are a number of advantages:
- air circulates calmly throughout the room;
- heat spreads evenly;
- a person can work actively in conditions with water heating, it is absolutely safe.
The heated air enters the room where it mixes with environment and the temperature is balanced. Sometimes you need to reduce energy costs. To do this, using filters, the air is purified and reused for heating industrial buildings.
Air heating
Most enterprises during their existence Soviet Union used a convection heating system for industrial buildings. The difficulty in using this method is that warm air, according to the laws of physics, rises, while the part of the room located near the floor remains less heated.
Today, more efficient heating is provided by an air heating system for industrial premises.
Operating principle
Hot air, which is preheated in the heat generator through air ducts, is transferred to the heated part of the building. Distribution heads are used to distribute thermal energy throughout the space. In some cases, fans are installed, which can be replaced by portable equipment, including a heat gun.
Advantages
It is worth noting that such heating can be combined with various supply systems ventilation and air conditioning. This is what makes it possible to heat huge complexes, something that could not be achieved before.
This method is widely used in heating warehouse complexes, as well as indoor sports facilities. In addition, such a method in most cases is the only possible one, since it has the highest level fire safety.
Flaws
Naturally, there were some negative properties. For example, installing air heating will cost the owners of an enterprise a pretty penny.
Not only do the fans necessary for normal operation cost quite a lot, but they also consume huge amounts of electricity, since their productivity reaches about several thousand cubic meters per hour.
Infrared heating
Not every company is ready to spend a lot of money on an air heating system, so many prefer to use another method. Infrared industrial heating is becoming increasingly popular every day.
Principle of operation
An infrared burner operates on the principle of flameless combustion of air located on the porous part of the ceramic surface. The ceramic surface is distinguished by the fact that it is capable of emitting a whole spectrum of waves that are concentrated in the infrared region.
The peculiarity of these waves is their high degree permeability, that is, they can freely pass through air currents in order to transfer their energy to specific place. The stream of infrared radiation is directed to a predetermined area through various reflectors.
Therefore, heating industrial premises using such a burner allows for maximum comfort. In addition, this heating method makes it possible to heat both individual work areas and entire buildings.
Main advantages
At the moment, the use of infrared heaters is considered the most modern and progressive method of heating industrial buildings due to the following positive characteristics:
- quick heating of the room;
- low energy intensity;
- high efficiency;
- compact equipment and easy installation.
By performing the correct calculation, you can install a powerful, economical and independent heating system for your enterprise that does not require constant maintenance.
Scope of application
It is worth noting that such equipment is used, among other things, for heating poultry houses, greenhouses, cafe terraces, auditoriums, shopping and sports halls, as well as various bitumen coatings for technological purposes.
The full effect of using an infrared burner can be felt in those rooms that have large volumes of cold air. The compactness and mobility of such equipment makes it possible to maintain the temperature at a certain level depending on the technological need and time of day.
Safety
Many people are concerned about the issue of safety, since they associate the word “radiation” with radiation and harmful influence on human health. In fact, the operation of infrared heaters is completely safe for both humans and equipment located in the room.
SNiP standards for heating industrial premises
Before you start designing a particular system, and think about which industrial heating boiler to choose, you need to study the following rules and follow them. It is imperative to take into account heat loss, because not only the air in the room heats up, but also equipment and objects. The maximum temperature of the coolant (water, steam) is 90 degrees, and the pressure is 1 MPa.
