Water Source Heat Pump: It is a heat pump type integrated water air or water water air air air air air conditioning unit that can perform cooling/heating cycles using water as the heat source. It uses water as the heat source for heating and as the heat source for cooling.
It uses water circulating in shared pipelines, water extracted from wells, lakes, or rivers, or water circulating in underground coils as a cold (hot) source to produce cold (hot) air or cold (hot) water; Including a user side heat exchange device, compressor, and heat source side heat exchange device, with single refrigeration or refrigeration and heating functions.
Classified by the form of heat exchange equipment used: hot and cold air source heat pump units, hot and cold water source heat pump units
Classified by cold (hot) source type: water ring water source heat pump unit, underground water source heat pump unit, underground loop water source heat pump unit.
Working principle
The working principle of winter heating: The water pump extracts groundwater from the lifting well and sends it to the water source heat pump unit. The low-grade thermal energy of the groundwater is absorbed by the unit and then sent back to the ground through the reinjection well. It exchanges heat with the earth again to increase the thermal energy and is reused.
The liquid refrigerant in the water source heat pump unit absorbs low-grade thermal energy from groundwater in the evaporator, evaporates into low-temperature and low-pressure gaseous refrigerant, and is compressed by the compressor into high-temperature and high-pressure gaseous refrigerant before being 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 condenses into a liquid state and returns to the evaporator, repeating the process of heat absorption and exchange.
