水源熱泵原理
Principle of water source heat pump
通過輸入少量高品位能源（如電能），實現(xiàn)低溫位熱能向高溫位轉移。水體分別作為冬季熱泵供暖的熱源和夏季空調的冷源，即在夏季將建筑物中的熱量“取”出來，釋放到水體中去，由于水源溫度低，所以可以高效地帶走熱量，以達到夏季給建筑物室內制冷的目的；而冬季，則是通過水源熱泵機組，從水源中“提取”熱能，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.
