HEATING

To maintain normal human life and well-being, it is necessary that the amount of heat released into the environment is equal to the amount of heat produced by the human body. If this equality is violated, the human body becomes overheated or overcooled, which equally worsens the health and, consequently, the performance of the person.

The process of artificially maintaining a certain air temperature in a room is called heating.

If the indoor temperature is maintained above the ambient air temperature, the external envelope of the premises generates a heat flow that is directed from the premises to the outside. In this case, the temperature of the inner surfaces of the enclosure will always be lower than the temperature of the air inside the room, as heat flow is only possible from a heated environment to a less heated environment.

In order to maintain the desired temperature inside the room, a certain heat flow from the heating system is required.

Heating system – is a set of devices that perform the function of heating – heating boilers, network pumps, heating networks, devices for automatic temperature control in the premises, heating radiators, convectors, etc.

The operation of heating is characterised by a certain frequency throughout the year and a variable nature of the power consumption of the heat source. This depends primarily on the meteorological conditions and climate of the area in which the heated building is located. Obviously, with a decrease in the outside temperature, the amount of heat supplied through heating should increase, and with an increase in the outside temperature and the influence of solar radiation, on the contrary, it should decrease.

Our experts will take care of choosing the right system for your needs, based on many factors: type of room, purpose, area, equipment goals, budget and much more.

VENTILATION AND AIR CONDITIONING

Comfortable conditions that ensure normal health and high productivity of people depend on environmental parameters, i.e. the climate in the area and the time of year, as well as on the intensity of work and the type of production.

Modern living conditions require effective artificial means of improving the air environment. Air conditioning can be one of the solutions to this problem.

Human health, performance, and well-being are largely determined by the microclimate and air environment in the premises. Modern automated air conditioning systems maintain the set parameters of indoor air regardless of fluctuations in environmental parameters. Air conditioning is carried out by a set of technical means called an air conditioning system.

Air as a factor of human life should be considered from two perspectives: as an environment inhaled by a person and as an environment surrounding a person with which the surface of the human body is constantly in contact. The role of air is to supply a person with oxygen, remove moisture from the body when exhaled, and ensure the process of heat exchange between a person and the environment. With the help of air conditioning, it is possible to completely eliminate or minimise the effects of such harmful factors as excess heat, excess water vapour: moisture; gases and vapours of chemicals with toxic or irritating effects; toxic and non-toxic dust; radioactive substances.

Air conditioning – is the automatic maintenance of all or certain air parameters (temperature, relative humidity, cleanliness, traffic speed) in enclosed spaces at a certain level in order to ensure predominantly optimal meteorological conditions that are most favourable for people’s well-being, technological processes, and the preservation of cultural values.

Air conditioning is provided due to the impossibility of using natural ventilation (open windows in summer) due to extreme street noise that interferes with work, indoor air pollution or high wind speeds at high storey levels.

The purpose of air conditioning systems is to create comfortable conditions for people to stay indoors. The thermal comfort of a person is influenced by the temperature and humidity conditions in the room and air mobility, but the gas composition of the air, i.e. the presence of harmful substances in the air, affects the normal functioning of various body subsystems.

Air conditioning systems are provided with cleaning products:

• air from dust, bacteria and odours;
• heating, humidifying and dehumidifying it;
• movement, distribution and automatic regulation of air temperature, relative humidity, and sometimes by means of regulating the gas composition and content of charged ions in the air, as well as by means of remote control and monitoring

The air conditioning systems of large public buildings are serviced by comprehensive automated control systems. The use of heat pumps in air conditioning ensures optimum comfort all year round and easy switching from heating to air conditioning.

Purpose of ventilation – Maintain the chemical composition and physical condition of the air that meets hygiene requirements, i.e. ensure the required air purity, temperature, humidity and speed. The required air purity is regulated by sanitary standards that set maximum permissible concentrations of harmful impurities. To meet these standards and requirements, polluted air must be removed from industrial, public and residential premises and fresh air must be introduced from the atmosphere.

Natural ventilation of the premises occurs due to the exchange of air through windows, doors and special ventilation openings in the external envelope of the building. The intensity of natural ventilation can reach three times an hour. With natural ventilation, air exchange occurs unevenly in different parts of the room, as fresh air mixes with polluted air in a disorganised manner. With natural ventilation, the air is not preheated; during the heating season, it is heated by the room heating system.

Forced ventilation is more efficient than natural ventilation. It provides any given intensity of air exchange, allows you to evenly ventilate all parts of the room and avoid uneconomical mixing of fresh air with polluted air. The contaminated air is removed from the room by special exhaust ventilation systems and replaced with fresh air supplied by the supply ventilation system. At the same time, the heat of the exhausted air can be used to heat the fresh air in a special heat exchanger.

Modern engineering and technical equipment is capable of creating any indoor air conditions that ensure full environmental comfort. This equipment allows you to enrich the air with oxygen, heat or cool it, dry or humidify it, clean it from dust or other contaminants, and flavour it.

There are many classifications of ventilation and air conditioning types and parameters.
