HEAT PUMP

摘要

The heat pump exchanger (9) has channels forming the evaporator (8) of the heat pump and is traversed by air circulation channels (10) associated to a fan (13), generating forced circulation of air through the channels (10). The channels forming the evaporator (8) and the air circulation channels (10) are arranged alternately side by side, adjacent to a surface (9a) of the heat exchanger (9) used for collecting incident solar energy. The combination of forced convection of air and of the collection of solar energy increases the efficiency of the heat pump. Furthermore, the collecting surface (9a) of solar energy of the heat exchanger (9) is used for defrosting the air circulation channels (10).
