(上接2015年第7期第43页)第五讲制冷系统窗式空调工作原理①温度感应器将需要制冷的信号传送到恒温调节器。②将制冷剂压缩进入热的气体(图1)。③热的气体被冷却,冷凝成为液体,在通过屋外的热交换器时,与风扇带动的房屋外空气进行热交换。④冷却的液体经过一个减压阀,蒸发成为低温低压气体,进入屋内的热交换器。⑤内置的风扇将屋内的热空气带动进入 (Continued on page 7 2015 第 43 页) The fifth speech refrigeration system window air conditioner works ① temperature sensor will need to send the signal cooling to the thermostat. ② refrigerant compressed into the hot gas (Figure 1). ③ hot gas is cooled, condensed into a liquid, through the outdoor heat exchanger, with the fan-driven heat exchange outside the house of air. ④ cooled liquid through a pressure reducing valve, evaporated into low temperature and low pressure gas, into the house heat exchanger. ⑤ built-in fan will drive the hot air inside the house
