When the water in the circulation water path formed by the cooling first branch 331 and the cooling second branch 332 flows through the heat exchange water tank 323, heat is continuously transferred to the cold end of the semiconductor refrigeration chip 321 through the heat exchange member, so that the temperature of the circulating water is reduced, and meanwhile, the heat end of the semiconductor refrigeration chip 321 is radiated through the radiator 322, so that the refrigeration performance of the semiconductor refrigeration chip 321 is improved.

As another preferred embodiment of the present invention, the second pipeline 43 includes a heat supply first branch 431 and a heat supply second branch 432 connected in parallel to the heat supply first branch 431, the heat supply first branch 431 is provided with a heat supply unit water pump 433, a heat supply unit water tank 434 and a heating module 42, the heat supply second branch 432 is provided with a phase change heat accumulator 41 and a heat supply unit valve 435, a connection section between a connection point of a water outlet end of the heat supply first branch 431 and the heat supply second branch 432 and the water outlet pipeline 5 is provided with a heat supply unit check valve 436, and a reverse port of the heat supply unit check valve 436 is connected to the water outlet pipeline 5. It should be noted that the connection point of the water outlet end of the heating first branch 431 and the heating second branch 432 refers to the connection point of the heating first branch 431 and the heating second branch 432 away from the end of the pumping device 6.

In this embodiment, when no water is needed, the phase change heat accumulator 41 is heated, the pumping device 6 and the heat supply unit valve 435 are opened, the first branch 431 is closed, the water in the water tank 1 enters the second branch 432 via the tank pipe 2, and is injected into the water tank 434 from the heat supply unit valve 435, when the water in the water tank 434 of the heat supply unit is filled, the pumping device 6 is turned off, the water pump 433 of the heat supply unit is turned on, the first branch 431 of the heat supply and the second branch 432 of the heat supply form a circulating water path, the heating module 42 is operated, the circulating water in the circulating water path and the heating module 42 are continuously subjected to heat exchange to raise the water temperature, meanwhile, the circulating water and the phase-change heat accumulator 41 also exchange heat to raise the temperature of the phase-change heat accumulator 41, so that the phase-change heat accumulator 41 reaches above the phase-change temperature, the heating module 42 stops running, and the heat supply unit water pump 433 is turned off; when water needs to be supplied, the pumping device 6, the heat supply unit valve 435 and the heat supply unit one-way valve 436 are opened, the normal-temperature water in the water tank 1 enters the heat supply second branch 432 through the water tank pipeline 2, and when the normal-temperature water flows through the phase-change heat accumulator 41, the normal-temperature water exchanges heat with the phase-change heat accumulator 41 through the heat supply second branch 432, the phase-change heat accumulator 41 is changed from a liquid state to a solid state, a large amount of heat is rapidly released, and the normal-temperature water enters the water outlet pipeline 5 through the heat supply unit one-way valve 436 after. It should be noted that, at this time, a small amount of water may enter the heat supply unit water tank 434 from the connection point of the water outlet ends of the heat supply first branch 431 and the heat supply second branch 432, but the heat supply unit water tank 434 is in a sealed state, the heat supply unit water pump 433 is in a closed state, the amount of water shunted into the heat supply unit water tank 434 is limited, and the water output of the water outlet pipeline 5 is not significantly affected.

When the circulating water path is used for heating the heat storage phase change material 44, the heating time of the water flow in the heat supply second branch 432 to the heat storage phase change material 44 is prolonged, and the conditions of overhigh local temperature and uneven heat transfer during single-point heating of the heat storage phase change material 44 can be effectively avoided; when the heat storage phase change material 44 is used for rapidly heating the normal temperature water, the heat transfer time between the normal temperature water and the heat storage phase change material 44 is further increased, and the heating effect on the normal temperature water in the heat supply second branch 432 is faster and better.

Specifically, a heating water level monitor 437 is disposed in the heating unit water tank 434 and used for monitoring the water level in the heating unit water tank 434, the heating water level monitor 437 may be connected to a controller of the water supply system, and after it is monitored that the water in the heating unit water tank 434 is filled, the pumping device 6 is automatically controlled to be turned off by the controller, the heating unit water pump 433 is turned on, and the phase change heat accumulator 41 is heated by the heating module 42.
