What is a water source heat pump
Water source heat pump is a kind of energy-efficient air-conditioning system that can use both the surface of the earth or shallow water (such as groundwater, rivers and lakes), or artificial regeneration of water (industrial wastewater, geothermal tail water, etc.) Water source heat pump technology using heat pump units to achieve low-temperature heat transfer to high temperature, the water body and the formation of storage in winter and summer as a heating source of heat and air-conditioning cold source, that is, in winter, the heat in the water and formation "take" Come out, increase the temperature, the supply of indoor heating; Summer, the indoor heat taken out, released into the water and strata. From an academic point of view, it can be classified as a water source heat pump system when all the objects used are water bodies and stratum (aquifer), and water and water are used as heat and cold sources for heat pump units. According to the classification of ashrae handbook: hvac applications. (1995), geothermal energy resources are divided into three categories according to their temperature ranges. Among them, ground source heat pump applications include two types of water source heat pumps: groundwater sources and surface water source heat pumps.
