ABSTRACT
In recent years the solar energy has found wide use for different purposes. It has been energy resource for hot water preparation and supply, for generation of electricity, for ventilation of buildings, and in a range of industrial buildings, etc. The exception in this area have made the wintertime solar heating of residential, public and industrial buildings, which is due to the climatic conditions of the geographical areas. As well as the insufficient energy intensity of the sun and the large fluctuations in temperature during the day. Apart from above-mentioned reasons, the problem has not been solved due to the lack of necessary technologies of efficient use of solar energy for heating purposes. In order to eliminate the mentioned disadvantages, the authors of this article have suggested new type of heating and ventilation combined systems. For both of mentioned heating and ventilation systems as working substance have been chosen the outside fresh air.
