Fig. 1 is general heat pump air conditioner hot water schematic diagram;
Fig. 2 is the utility model solar energy one geothermal heat pump air-conditioner hot water facility schematic diagram;
The specific embodiment:
Below in conjunction with accompanying drawing specific embodiments of the present utility model is described in further detail:
The utility model is connected with an end of domestic hot-water's heat exchanger 2 with the exhaust outlet of copper pipe with refrigeration compressor 1, the other end of domestic hot-water's heat exchanger 2 is connected with an end of cross valve 6, the other end of cross valve 6 respectively with condenser 5, magnetic valve 16 connects, condenser 5 is connected with device for drying and filtering 7 and restricting element 10 with the other end of magnetic valve 16, device for drying and filtering 7 and check valve 8, restricting element 9 is chained together, restricting element 10 and check valve 11, device for drying and filtering 12 is chained together, the other end of restricting element 9 and device for drying and filtering 12 links to each other with an end of evaporimeter 13, the other end of evaporimeter 13 links to each other with an end of cross valve 6, the other end of cross valve 6 respectively with magnetic valve 17, one end of solar energy heating pipe evaporator 18 links to each other, magnetic valve 17, the other end of solar energy heating pipe evaporator 18 links to each other with an end of gas-liquid separator 15, and the other end of gas-liquid separator 15 links to each other with the air entry of compressor 1.
Under the operating mode that heats in the winter time, condenser 5 is made evaporimeter usefulness, if condenser 5 is water cooled condensers, ground heat exchanger 4 is connected with the water inlet pipe and water outlet pipe of condenser 5, the heat energy of absorption refrigerating water is evaporated in the winter refrigeration agent in condenser 5, chilled water is recycled to ground heat exchanger 4, absorbs underground heat energy.Under the operating mode that heats in the winter time, evaporimeter 13 is made condenser usefulness, if evaporimeter 13 is water-cooled evaporimeters, water pipe 14 is connected to indoor heating with the indoor fan coil pipe.Domestic hot-water's heat exchanger 2 is used for making life hot water.
