A coolant (1) aerosol, supercooled to the level lower than that of the coolant evaporating temperature in front of the evaporator (2) is sucked in a compressor (3) housing (3.1). The coolant (1) supercooling and generation of aerosol is solved by the bypass (6) of the evaporator (2), which provides injection of a needful amount of the liquid coolant into gas after the evaporator. In the compressor (3) housing (3.1), the liquid coolant (1) evaporates; gas is preheated, sucked in by the compressor, pressed and heated. At the same time, the coolant (1) evaporating temperature in front of the evaporator (2) increases. This makes possible suction of a grater weight amount of the coolant (1) by the compressor (3) and by a slight increase of the compressor electric power demand a substantial increase of a performance factor and output of a heat pump. The invented method can be used for all designs of the heat pumps using a hermetically closed compressor with electric motor. |
