[0002] The constant temperature heat pump processes the refrigerant through the compressor, discharges the high-temperature and high-pressure refrigerant, passes through the corrosion-resistant water heat exchanger, transfers the heat to the water side, heats the water, and the refrigerant passing through the water side becomes the refrigerant at normal temperature and high pressure, then passes through the throttling component for throttling expansion to form the low-temperature and low-pressure refrigerant, passes through the fin heat exchanger, absorbs heat from the air, and then returns to the compressor, the reciprocating cycle heats the water.

[0003] At present, the existing solutions for the geothermal heat pump system of swimming pools and SPA pools are to heat with separate units, and each system is equipped with a heating device; that is, the swimming pool is equipped with a set of swimming pool constant temperature heat pumps, and the SPA pool is equipped with a set of SPA heating equipment. However, the application end of the market usually only uses the swimming pool for swimming in spring, summer and autumn, and does not go to the swimming pool for swimming in winter; in winter, the SPA pool will be used, so there is a problem of low equipment utilization.

The SPA pool is usually in a relatively small pool body, and the water outlet of the equipment is connected to the SPA pool water. Because the SPA pool is small, it will directly contact people and easily cause burns. Utility Model Content
