制冷工质在蒸发器内吸取热量，温度升高变成过热蒸气，进入压缩机重复循环过程。
Working in the evaporator refrigeration in heat, temperature from overheating steam into the compressor, become repeat process.
循环开始时，制冷剂以低温低压的蒸气，进入一个电机驱动的压缩机。
The refrigerant, starting as a low-temperature, low-pressure vapor, enters a compressor driven by an electric motor.
该压缩机的速度被改变以控制该制冷剂的流速和配合蒸气压缩系统的冷却负荷需求。
The speed of the compressor is varied to control the refrigerant flow rate and match the cooling load requirements of the vapor compression system.
