The principle of water source heat pump unit is that the heat transferred to the water in summer, because the water temperature is low, so it can effectively take the heat, while the winter, the heat extracted from the water source.
The following is the main work principle: in the cooling mode, high temperature and high pressure refrigerant gas enters the condenser from the compressor, refrigerant to the cooling water (groundwater) heat release, the formation of high temperature and high pressure liquid, and the cooling water temperature rise. The refrigerant is expanded into a low temperature and low pressure liquid through the expansion valve, and enters the evaporator to absorb the heat in the freezing water (water in the building refrigeration), and the steam is evaporated into a low-pressure steam, and the water temperature of the frozen water is reduced. Low pressure refrigerant vapor is compressed into a high temperature and high pressure gas, so that it can be circulated in the evaporator to obtain the chilled water.
In heating mode, high temperature and high pressure refrigerant gas enters the condenser from the compressor, refrigerant to the hot water supply (water heating) in the heat and cooling into high pressure liquid, and the heating water temperature rise. The refrigerant is expanded into a low-temperature low-pressure liquid through the expansion valve, and enters the evaporator to absorb heat in the low temperature heat source water (ground water), and the steam is evaporated into a low pressure steam, and the water temperature of the low temperature heat source water is reduced. Low pressure refrigerant vapor and enter the compressor compressed into high temperature and high pressure gas, so the cycle of heat supply in the condenser water.
