The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the utility model is achieved like this, it comprises compressor 1, cross valve 2, plate type heat exchanger I 3, boiler 4, reservoir 5, filter 6, throttling arrangement 7, the second magnetic valve 9, fan heat exchanger 11 and gas-liquid separator 14, its structure is, two air-condition freezing water pipes 15 that it also comprises the first magnetic valve 8, check valve 12, plate type heat exchanger II 10 and is connected to plate type heat exchanger II 10 the same sides; The first magnetic valve 8, plate type heat exchanger II 10 and check valve 12 are connected on a pipeline successively, and the second magnetic valve 9 and fan heat exchanger 11 are connected on another pipeline successively, and the two ends after two pipeline parallel connections connect respectively e pipe and the throttling arrangement 7 of cross valve 2; The first magnetic valve 8, check valve 12, plate type heat exchanger II 10 and the water source heat absorbing end that is connected to a Hot water units of two air-condition freezing water pipes, 15 formations of plate type heat exchanger II 10 the same sides, the second magnetic valve 9 and fan heat exchanger 11 form the air-source heat absorbing end of Hot water units.
End after throttling arrangement 7, filter 6, reservoir 5 and plate type heat exchanger I 3 are contacted is successively connected with the c of cross valve 2 pipe, and plate type heat exchanger I 3 connects boiler 4 by two water pipes;
Compressor 1 is connected with gas-liquid separator 14, and gas-liquid separator 14 connects a pipe of cross valve 2, and compressor 1 connects the s pipe of cross valve 2.
One in described two air-condition freezing water pipes 15 is connected with water pump 16, and this water pump 16 is transported to plate type heat exchanger II 10 by the water with heat energy on the one hand, the refrigerant heat absorption of supplying hot water unit; On the other hand the cold water after cooling is transported to central air-conditioning by air-condition freezing water pipe 15, the free cooling down water providing to central air-conditioning.One in described two water pipes 17 is also connected with water pump 16, and this water pump 16 is the mobile power that provides of water circulation for plate type heat exchanger I 3 and boiler 4.
