In summer, the high-temperature high-pressure refrigerant gas that compressor 1 produces, by heat recovering heat exchanger 4 with heat transferred domestic hot-water supply system, cold-producing medium has become high pressure low temperature liquid, again by cross valve 3, supplementary heat exchanger 5 to expansion valve 8, in expansion valve 8 through the throttling thermal procession, become low-temp low-pressure gas, and emit a large amount of colds, and cold is taken away by the air conditioner water circulation at air-condition heat exchanger 6 places, satisfy the needs of air conditioner refrigerating; The low-temperature low-pressure refrigerant that comes out from air-condition heat exchanger 6 is got back to compressor 1 through cross valve 3 and gas-liquid separator 2 and is entered next circulation simultaneously.
If the domestic hot-water satisfies the demand, then stop the heat exchange at heat recovering heat exchanger 4 places, start the heat exchange of supplementary heat exchanger 5, to guarantee the stable operation of unit.
In the winter time, the high-temperature high-pressure refrigerant gas that compressor 1 produces, after heat recovering heat exchanger 4 is with the heat transferred hot water supply system, become high pressure low temperature liquid, again by cross valve 3 and air-condition heat exchanger 6, as this moment heat recovering heat exchanger 4 just producing the domestic hot-water, then air-condition heat exchanger 6 quits work, stop to produce the domestic hot-water as heat recovering heat exchanger 4, then air-condition heat exchanger 6 is taken away heat the thermal cycle of heating system contentedly by the circulation of floor heating water; The heating power throttling process that the cryogenic high pressure cold-producing medium that comes out from air-condition heat exchanger 6 passes through expansion valve 11 becomes low-temp low-pressure gas, discharges cold through supplementary heat exchanger 5, and is back to compressor 1 by cross valve 3 and gas-liquid separator 2, enters next circulation.
Therefore in the winter time, heat recovering heat exchanger 4 and air-condition heat exchanger 6 can carry out heat exchange, and heat recovering heat exchanger 4 provides domestic hot-water's heat, the heat that air-condition heat exchanger 6 provides floor heating to need.Because the thermal inertia of ground heating system is bigger, and domestic hot-water's supply fluctuation is big, and the complementation of the two helps the stable operation of unit.
Spring or autumn, when not needing floor heating or air-conditioning, the high-temperature high-pressure refrigerant that start back compressor produces is after heat recovering heat exchanger 4 is with the heat transferred hot-water heating system, become high pressure low temperature liquid, by cross valve 3 air-condition heat exchanger 6 of flowing through, do not carry out heat exchange at air-condition heat exchanger 6 places, the high pressure low temperature cold-producing medium that comes out is through the heating power throttling process of expansion valve 8, become low-temp low-pressure gas, through supplementary heat exchanger 5 released cold quantities, be back to compressor 1 by cross valve 3 and gas-liquid separator 2 again and enter next circulation.
