水源热泵原理
Principle of water source heat pump
通过输入少量高品位能源（如电能），实现低温位热能向高温位转移。水体分别作为冬季热泵供暖的热源和夏季空调的冷源，即在夏季将建筑物中的热量“取”出来，释放到水体中去，由于水源温度低，所以可以高效地带走热量，以达到夏季给建筑物室内制冷的目的；而冬季，则是通过水源热泵机组，从水源中“提取”热能，送到建筑物中采暖。
A small amount of energy (such as high-temperature energy level) is transferred to high-temperature energy level through low-temperature energy level. The water body is used as the heat source of heat pump heating in winter and the cold source of air conditioning in summer, that is, the heat in the building is "taken out" and released into the water body in summer. Because the water source temperature is low, it can efficiently take away the heat, so as to achieve the purpose of indoor cooling of the building in summer; In winter, the heat energy is "extracted" from the water source through the water source heat pump unit and sent to the building for heating.
