Abstract

The article deals with the factors influencing the change in the parameters of the microclimate as a result of changes in the oper ational characteristics of the elements of the heating system of the building. For each of the factors, the basic laws that ca n describe the change in the thermal and hydro technical characteristics, both elements of the heating system and its work in general, are established.  Purpose.  Identify  the  basic  patterns  of  changes  in  the  heat-hydro-technical  characteristics  of  heating  systems,  which  can change during the operation, for further calculation of the parameters of the microclimate in the room.  Findings. Having considered the factors that change the characteristics of the water heating system of the building, it has been established that providi ng the optimal parameters of the microclimate in the premises of buildings largely depends on the operational characteristics of the heating systems.  Practical value.  Identification of factors will allow to predict and evaluate changes in the parameters of the microclimate as a result of changes in the operational characteristics of heating systems.
