The working temperature range of the swimming pool heat pump is -5℃ to 43℃. The swimming pool heat pump heats by absorbing ambient heat. Its working temperature is limited by the exhaust temperature of the compressor and usually does not exceed 120℃. In actual engineering applications, in order to ensure the energy efficiency ratio, it is usually limited to -5℃ to 43℃ (the low-temperature type can reach -25℃ but the energy efficiency ratio will be reduced).
The hot water temperature of the swimming pool heat pump is usually 55℃ to 60℃. This is because the water temperature exceeding 60℃ will significantly reduce the energy efficiency ratio (the COP value drops by about 30%), and it is easy to cause high-pressure protection of the system. Therefore, the national standard stipulates that the rated temperature of the storage heat pump water heater is 55℃, and the instant type can reach 60℃.
