By recovering the heat energy in the bath wastewater, a clean energy source is developed, the emission of urban waste heat is reduced, and the environment is protected.
It can be understood that the sewage source heat pump unit 100 comprises a sewage treatment unit and a heat exchange unit, wherein the bath sewage contains solid and liquid impurities such as hair, shampoo and the like, and the bath sewage in the sewage tank is treated by the sewage treatment unit, so that the corrosiveness of the sewage is reduced, the impurities can be prevented from blocking a system pipeline, the service life of the system is ensured, and the extraction of the heat of the sewage is facilitated; before entering the sewage heat exchanger, impurities in sewage are discharged into a sewage main channel by utilizing a filter, the sewage after filtering treatment is gathered into a reclaimed water system, heat is transferred to a refrigerant in a heat pump through an evaporator, and finally, the heat is transferred to hot water to be used again through a condenser, so that the recycling of heat energy is realized.
In this embodiment, the pipe system includes a main water return pipe 200, a main temperature control three-way valve 400 is disposed on the main water return pipe 200, the main water return pipe 200 is connected to a water inlet end 401 of the main temperature control three-way valve 400, the main temperature control three-way valve 400 further includes a first water outlet end 402 and a second water outlet end 403, the first water outlet end 402 is connected to a first water return branch pipe 210, and the first water return branch pipe 210 is connected to a water return inlet end 310 of the hot water storage tank 300; the second water outlet 403 is connected to the second water return branch 220, and the water in the second water return branch 220 is heated by the electric heating device 500 and then enters the water return inlet 310 of the hot water tank 300.

Thus, it is possible to ensure that the hot water outputted from the sewage source heat pump unit 100 can enter the hot water tank 300 in a state of reaching a predetermined temperature.
When the temperature of the hot water entering from the water inlet end 401 of the main temperature control three-way valve 400 meets a preset value, the first water outlet end 402 is opened, the second water outlet end 403 is closed, and the state is an initial state; conversely, when the temperature of the hot water entering from the water inlet end 401 of the main temperature control three-way valve 400 is less than a preset value, the first water outlet end 402 is closed, and the second water outlet end 403 is opened.
It should be understood that the main temperature control three-way valve 400 is switched from the initial state to the state in which the first water outlet 402 is closed and the second water outlet 403 is opened, and a temperature value (hereinafter referred to as a temperature standard value T for convenience of description) should be matched in advance 0 ) When the temperature of the hot water entering from the water inlet end 401 of the main temperature control three-way valve 400 is lower than the standard temperature value, the first water outlet end 402 of the main temperature control three-way valve 400 is closed, and the second water outlet end 403 is opened.

The temperature of the hot water entering from the water inlet end 601 of the auxiliary temperature control three-way valve 600 is lower than the temperature standard value T by a certain allowance 0 When the temperature of the hot water entering from the water inlet end 601 is lower than the second temperature threshold T l At this time, the hot water enters the return branch pipe three 230, is heated by the electric heating device 500, and then enters the hot water tank 300.
