Ventilation of buildings in winter period, especially in cold climatic conditions, requires rather big quantity of heat for preheating the ventilation fresh air. Consequently, an average low-income family pays a tangible cost for ventilation of apartments. To provide low cost ventilation of houses it is becoming attractive the use of solar energy for preheating the outside fresh air, before its supplying into the house. For this purpose, cheap solar air heaters are needed. To solve this problem a simple and cheap construction of solar air heater was developed, which is the main part of the ventilation system. The system consists of air heating solar collectors, installed on the roof of the house, warm air distribution ductwork, internal air circulation ducts and air-circulating fan. In summer period, the system is used only during nighttime period for circulating outside colder air through the internal space of the house. Such operation allows cooling internal air and as well the constructions of the house. As a result, the house accumulates nighttime natural cold for using it at daytime cooling purposes. Presentation includes the scheme, explanation of operation and method for design of suggested ventilation system. Analysis proved the energy efficiency and cost effectiveness of the new system.
