英语翻译水环热泵空调系统是指小型的水/空气热泵机组的一种应用方式,即用水环路将小型的水/热泵机组并联在一起,形成一个封闭环路,构成一套回收建筑物内部余热作为其低位热源的热泵供暖、供冷的空调系统.水环热泵空调系统的基本工作原理是：在水/空气热泵机组制热时,以水循环环路中的水为加热源；机组制冷时,则以水为排热源.当水环热泵空调系统制热运行的吸热量小于制冷运行的放热量时,循环环路中的水温度升高,到一定程度时利用冷却塔放出热量；反之循环环路中的水温度降低,到一定程度时通过辅助加热设备吸收热量.只有当水/空气热泵机组制热运行的吸热量和制冷运行的放热量基本相等时,循环环路中的水才能维持在一定温度范围内,此时系统高效运行.

The water loop heat pump (WLHP) air-conditioning system is an application form of the small water/air heat pump assembly, namely, connecting small water/air heat pump units in parallel using a water loop, forging a closed loop, and forming a set of heating and cooling air-conditioning system by recycling heat residuals inside buildings as a low-grade heat source. The basic working theory of the WLHP air-conditioning system is as follows: when the water/air heat pump assembly heats, water in the water recycling loop works as the heating source; when cooling, the water works as source of heat drainage. When the heat absorption volume in the heating process of the WLHP air-conditioning system is smaller than the heat release volume in the cooling process, the temperature of water in the water loop rises, to a certain extent, a cooling tower is used to release the heat; reversely, when the temperature of water in the water loop goes down, to a certain extent, an assistant heater is used for the water to absorb heat. Only when the heat absorption volume in the heating process of the water/air heat pump assembly is approximately equal to the heat released in the cooling process, the temperature of water in the recycling loop can be kept within a certain range, and at the moment, the system runs with high efficiency.

Water loop heat pump air conditioning system is a kind of application mode of small water / air heat pump units,namely water loop will small water / heat pump units connected in parallel,to form a closed loop,a set of recycling building waste heat as the air-conditioning system,the low heat source heat pump heating cooling.The basic working principle of water loop heat pump system is:at the water / air heat pump heating,the water circulation loop of water as the heating source; refrigeration unit,with water as the exhaust heat source.When the water loop heat pump air conditioning system is less than the heat release heat absorption refrigerating operation,circulation loop of water temperature,to a certain extent cooling tower heat utilization; and circulating loop in the water temperature is reduced,to a certain extent by the auxiliary heating device to absorb heat.Only when the water / absorption heat air heat pump unit and cooling operation of the heat release is basically the same,circulating loop in the water to keep in a certain temperature range,the system efficiency.
