Solar refrigeration cycle heat pump unit

摘要

In the present invention, high-temperature evaporation is performed as a low-stage heat source in winter, and hot air of an air tube heated by solar radiation is supplied to the low-side evaporation air heat exchanger, so that the low-temperature evaporation heat source is not insufficient in the cold weather, and the air tube is also used. It is composed of a volume-expandable transparent vinyl, and can be easily removed in summer or the change of season, and relates to a dual refrigeration cycle heat pump device using solar heat that does not occupy much storage volume. To this end, the present invention is a high stage side through a high stage compressor 10, a high stage four-way valve 11, a high stage heat exchanger 12, a high stage valve 1 (HV1), a high stage expansion valve 1 (H1) and a two-way heat exchanger 20. The refrigerant is circulated to the high stage compressor (10), and the water in the water tank (22) is circulated to the high stage heat exchanger (12) through the pump (23) to produce hot water; The low stage side is a low stage compressor (1), a low stage four-way valve (2), the two-way heat exchanger (20), a low stage valve (LV3), a low stage valve (LV1), a low stage expansion valve (L1), an air heat exchanger (21) and In a two-way refrigeration cycle heat pump device using solar heat in which the refrigerant circulates through the low stage four-way valve (2) to the low stage compressor (1), the air tube expands in volume with a blower fan having a larger capacity than the suction fan of the air heat exchanger Is provided; The air tube is made of transparent vinyl and the internal air is heated by solar radiation heat; The heated air of the air tube is supplied to the intake of the air heat exchanger, so that it is a source of evaporation heat of the low-stage refrigerant.
