Water Source Heat Pump: A heat pump type integral water-air or water-water air-conditioning device that uses water as the heat source and can perform a cooling/heating cycle. It uses water as the heat source for cooling. When using water as the heat source.

It uses water circulating in shared pipelines, water drawn from wells, lakes or rivers, or water circulating in underground coils as cold (heat) sources to produce cold (hot) air or cold (hot) ) Water equipment; including a use-side heat exchange equipment, a compressor, and a heat source-side heat exchange equipment, with a single cooling or cooling and heating function.

　　According to the form of heat exchange equipment on the use side: cold and hot air type water source heat pump units, cold and hot water type water source heat pump units

　　According to the type of cold (heat) source: water loop type water source heat pump unit, groundwater type water source heat pump unit, underground loop type water source heat pump unit.

  working principle

The working principle of heating in winter: the water pump takes the groundwater from the water extraction well and sends it to the water source heat pump unit. The groundwater with low-grade heat is absorbed by the unit, and then sent back to the ground through the recharge well, and it exchanges heat with the earth again to increase the heat energy and reuse it. .

　　The liquid refrigerant in the water source heat pump unit absorbs the low-grade heat energy of the groundwater in the evaporator and evaporates into a low-temperature and low-pressure gaseous refrigerant, which is compressed by the compressor into a high-temperature and high-pressure gaseous refrigerant and then sent to the condenser. The high-temperature and high-pressure gaseous refrigerant in the condenser transfers heat to the circulating water (geothermal or heating fins) of the building through heat exchange. After releasing heat to the building, it is condensed into a liquid state and then returned to the evaporator. Repeat The process of heat absorption and heat exchange.
