Why the air-conditioning supplyreturn water temperature is 7℃-12℃

Reason analysis of 7 degree water supply: 　　 1. Starting from the refrigeration unit, the refrigerant evaporates in the evaporator and absorbs heat to cool the secondary side water. If the evaporation temperature is too low, it will cause frost on the surface of the evaporator and affect the heat transfer efficiency.
