Water Source Heat Pump Unit: An integrated water-air or water-water air conditioning unit that utilizes water as its heat source for both refrigeration and heating cycles, using water as the heat source for heating and as the heat rejection source for cooling.
Equipment that uses water circulating in a common pipeline, 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 side heat exchanger, compressor, and heat source side heat exchanger, with single cooling or cooling with heating capabilities.
Water Source Heat Pump Units: Cold and Hot Air Type, Cold and Hot Water Type
By cold (hot) source type: Water Ring Water Source Heat Pump Units, Groundwater Water Source Heat Pump Units, Underground Loop Water Source Heat Pump Units.
Operating Principle
The working principle of winter heating: A pump extracts groundwater from the well and sends it to the water source heat pump unit. The groundwater, which has absorbed low-grade heat energy from the unit, is then returned to the ground through a recharge well. After re-exchanging heat with the Earth to increase its thermal energy, it is reused.
The liquid refrigerant in the water source heat pump unit absorbs low-grade thermal energy from groundwater in the evaporator, evaporating into a low-temperature, low-pressure gaseous refrigerant. This is then compressed by the compressor into a high-temperature, high-pressure gaseous refrigerant, which is sent to the condenser. In the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat through heat exchange to the building's circulating water (geothermal or radiator), releasing heat to the building before condensing back into a liquid and returning to the evaporator to repeat the process of absorbing and exchanging heat.
