The operation principle of the present invention is that the refrigeration working medium in refrigerating circuit 1 absorbs waste water by liquid-liquid heat exchanging evaporator 13
In heat, the rise of refrigeration working medium temperature, then by liquid-gas heat exchanging evaporator 14, from air absorbing heat becomes high temperature
Steam enters compressor 11.In compressor 11, the steam of high temperature is through overcompression, while the liberated heat of compressor 11 is absorbed,
Become the liquid of high temperature, heat is transmitted to the running water towards storage tank 22 in condenser 12, it is swollen that temperature is lowered into electronics
Swollen valve 15.In backheat stream 2, when hot shower arrangements 24 are not actuated (valve 72 is closed), running water passes through valve 71
Into regenerator 21 (now running water does not absorb heat in regenerator 21), heat is absorbed subsequently into condenser 12, is entered
Enter storage tank 22 in case using.If the water temperature in storage tank 22 does not reach use requirement, temperature control system 4 is opened to be followed certainly
Valve 74 in loop back path 3, while the water in the control compressor 11 working frequency rise of temperature control system 4, storage tank 22 is again
Secondary return in condenser 12 absorbs heat, makes temperature continue to raise, and is again introduced into storage tank 22 until reaching use requirement.When
When hot shower arrangements 24 start (valve 72 is opened), the hot water in storage tank 22 is discharged into wastewater collection pond 25 after,
When the waste water arrival in wastewater collection pond 25 is a certain amount of, then valve 73 is opened, the waste water in wastewater collection pond 25 is passed through into water
Pump 26 is pumped into discharge after regenerator 21 and the heat exchange of liquid-liquid heat exchanging evaporator 13 successively, and (now running water absorbs from regenerator 21
Heat).When liquid level is higher than design water level in storage tank 22, the control valve 71 of tank level control system 5 is closed, in storage tank 22
Water continues cycling through heating；When liquid level is less than design water level in storage tank 22, the control valve 71 of tank level control system 5 is opened, originally
Water is supplemented in time.
