Fig. 1 is a structural representation of the present utility model.
[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
The central hot-water heating system of a kind of stratified flow solar heat-preservation double-source heat pump comprises condenser 2, compressor 3, also comprises two evaporimeters 4,5; The arrival end of two evaporimeters 4,5, the port of export are respectively by being serially connected in the closed circulation loop with compressor 3, condenser 2, expansion valve 6, pipeline 7 behind two transfer valves; Two evaporimeters can switch mutually by two transfer valves.Described transfer valve can be three-way solenoid valve 81.Condenser 2 is connected to user's water tank 1 by pipeline.
In evaporimeter, cold-producing medium (as fluorine Lyons, ammoniacal liquor etc.) has absorbed a large amount of heat energy steam raisings and has been inhaled into compressor, is compressed into high temperature, gases at high pressure, enters and emits a large amount of heats in the condenser, gas cooled becomes liquid through the expansion valve step-down, and liquid is got back to gasification heat absorption once more in the evaporimeter.Condenser 2 heats a large amount of heats to the water in the user side water tank 1.
An evaporimeter in two evaporimeters is a water source evaporimeter 4; The water side of solar thermal collector 41 connects the water inlet end of stratified flow hot water storage tank 42, and the water side of stratified flow hot water storage tank 42 connects the water inlet end of evaporimeter 4, and the water side of evaporimeter 4 connects the water inlet end of stratified flow hot water storage tank 42.It is a thermal source with the hot water that is stored in the stratified flow hot water storage tank.Just begun to set solar thermal collector available machine time section, constantly the thermal energy storage that solar energy is produced is in the stratified flow hot water storage tank; The operation duration of system when the temperature difference of Inlet and outlet water is smaller, illustrates that the water in the heat collector heats not high enoughly by the temperature difference (T2-T1) control of solar thermal collector Inlet and outlet water, continues heating.And the water of evaporimeter 4 water sides is sent stratified flow hot water storage tank 42 again back to, is because hot water can not fall too lowly through evaporator temperature, can also utilize once again.
