INTEGRATED HEAT PUMP UNIT UTILIZING AIR ENERGY AND WATER SOURCE

摘要

An integrated heat pump unit utilizing air energy and water source comprises a compressor (1), a first heat exchanger (4), a second heat exchanger (5), a heat exchange tower (3), a water pump (12), an expansion valve (9) and a reversing valve (2). The first heat exchanger (4) is arranged in the heat exchange tower (3). An outlet (G) of the compressor (1) is connected to an inlet (A) of the first heat exchanger (4) by the reversing valve (2). An outlet (B) of the first heat exchanger (4) is connected to the inlet (C) and the outlet (D) of the expansion valve (9) respectively by check valves (16, 15). An inlet (E) of the second heat exchanger (5) is connected to the inlet (C) and the outlet (D) of the expansion valve (9) respectively by check valves (14, 13). An outlet (F) of the second heat exchanger (5) is connected to an inlet (H) of the compressor (1) by the reversing valve (2). The water pump (12) is arranged on the heat exchange tower (3) to supply the circulation power for the cooling medium in the tower. The unit can solve the problems of the climate instability of the air source, the condition limitation of the ground source and the water source, and excessive initial investment.
