制冷原理：

根據制冷系統原理，低溫低壓的液態冷媒在蒸發器里面與周圍水進行熱交換蒸發器吸收水的熱量，蒸發成低溫低壓的氣態，蒸發過程中冷媒溫度不變，低溫低壓氣態的冷媒進入到壓縮機，經壓縮機壓縮，被壓縮成高溫高壓的氣態，然后進入冷凝器，在冷凝器里與室內的介質進行熱交換，高溫高壓的氣態的部份熱量被介質吸收，介質溫度升高，冷媒放熱冷凝器變成高溫高壓液態，冷凝器過程溫度不變，然后進入膨脹閥進行節流，節流是迅速降溫的過程，冷媒變成低溫低壓的液態，此過程后的冷媒再進入到蒸發器進行換熱蒸發，從而實現制冷系統的整個過程，這種循環是連續進行的，水才得以連續不斷的制冷。

Principle of refrigeration:

According to the principle of the refrigeration system, the low temperature and low pressure liquid refrigerant carries out heat exchange with the surrounding water in the evaporator. Evaporates into a low temperature and low pressure gaseous state, during the evaporation process, the refrigerant temperature of the low temperature and low pressure gaseous state enters the compressor, is compressed by the compressor, and is compressed into a high temperature and high pressure gaseous state. Then into the condenser, in the condenser and the indoor medium heat exchange, high temperature and high pressure gaseous part of the heat is absorbed by the medium, the medium temperature rises, the refrigerant exothermic condenser into a high temperature and high pressure liquid, the condenser process temperature unchanged, and then into the expansion valve throttling, Throttling is the process of rapid cooling, the refrigerant becomes a liquid at low temperature and low pressure, the refrigerant after this process enters the evaporator for heat exchange evaporation, so as to achieve the entire process of the refrigeration system, this cycle is continuous, the water can be continuous refrigeration.

泳池熱泵技術就是采用逆卡諾循環原理，在高位能的推動下，將熱量從低位熱源流向高位熱源的技術，就是說把不能直接利用的熱源轉化為可利用的高品位熱源，從而達到部分節約一次性高位能源的技術。

Swimming pool heat pump technology is the use of reverse Carnot cycle principle, driven by high energy, the heat flow from the low heat source to the high heat source technology, that is to say, the heat source can not be directly used into the available high-grade heat source, so as to achieve part of the one-time high energy saving technology.

泳池熱泵因其低溫熱源種類不同，其工作原理也有所區別：地下水泳池熱泵系統，就是將地下水井內的地下水抽出送入泳池熱泵機組，與泳池熱泵的工作介質進行熱量交換后再回灌到原來的地層中去；地表水泳池熱泵系統，就是將江河的水在循環水泵的驅動下，經過處理直接流經泳池熱泵機組或通過中間換熱器進行熱交換的系統；土壤源泳池熱泵系統，就是以大地土壤為熱源將熱泵的換熱器埋在地面以下，利用泵的循環液體與大地土壤進行冷熱交換的系統；空氣源泳池熱泵系統，就是利用專用的工質吸收大氣中的熱量進行熱交換的系統。

ming pool heat pump because of its different types of low temperature heat source, its working principle is also different: groundwater swimming pool heat pump system, isSwim the groundwater in the groundwater well pumped into the swimming pool heat pump unit, and the pool heat pump working medium after heat exchange and then recharge to the original formation; Surface water pool heat pump system is the system that the river water is driven by the circulating water pump and directly flows through the pool heat pump unit or the heat exchange system through the intermediate heat exchanger. Ground source swimming pool heat pump system is a system that uses the earth soil as the heat source to bury the heat exchanger of the heat pump under the ground, and uses the circulating liquid of the pump to exchange heat and cold with the earth soil. Air-Source Swimming Pool Heat Pump System is a heat exchange system that uses special working fluid to absorb heat from the atmosphere.

泳池熱泵如此通過制冷劑的不斷循環與泳池池水交換熱量將水加熱，同時在運行中不釋放附加熱能，不排放有害物質，工質與池水完全分開，不會造成二次污染，屬于節能環保產品，故在倡導節能環保的今天，泳池熱泵必將迎來高速的發展。

Swimming pool heat pump through the continuous circulation of refrigerant and pool water exchange heat to heat the water, At the same time, it does not release additional heat energy during operation, does not emit harmful substances, and the working fluid and the pool water are completely separated, which will not cause secondary pollution, and belongs to energy-saving and environmental protection products, so in the promotion of energy-saving and environmental protection today, the swimming pool heat pump will usher in high-speed development.
