SCIENTIFIC AND METHODOLOGICAL FUNDAMENTALS OF CONSTRUCTION OF HEAT LOADS IN BUILDINGS WITH SOLAR ENERGY
Solar radiation is converted into heat energy by falling on the walls of a building and on the surface of household appliances.
Key words and phrases: heating buildings; hot air supply; even distribution of air temperature in the rooms; air exchange and air velocity
It is aimed at creating the most favorable conditions for people living, working and engaging in public works in buildings and structures, ie the normative microclimate. The basics of creating a microclimate in buildings are: heating of buildings; hot air supply; even distribution of air temperature in the rooms; air exchange and air velocity; humidity and so on.
When solar energy is used as a heat source in a heating system, it is called the use of sunlight in the heating system (helio device).
A solar device that receives sunlight absorbs solar radiation and converts it into heat energy.
Such heating systems are divided into low-temperature passive and active heating systems, depending on the method of using solar radiation.
A device that converts solar radiation into heat is called a passive low-temperature solar heating system if the device is used in a building or in a building structure.
For example, a building is a collector, a wall is a collector (Figure 1), a roof is a collector, and so on.

In the "building-collector" heating system, which works with passive low-temperature sunlight, the sunlight enters the room through the glass layer and enters the type of heat. The falling solar radiation hits the surface of the walls of the building and the surface of the appliances and is converted into heat energy. The surface temperature increases and this temperature propagates between rooms by convection and radiation to unlit surfaces. This means that the sunlit side of the building is chosen as the low-temperature passive heating device.
