在室外气温较高或者电压偏低时，小型风冷热泵空调会因过载而停机不能稳定运行。作者采用制冷剂旁通和减小蒸发器循环风量等２项卸载措施，提高空调器的适应能力，即在电压１８７V、室外干球温度４８℃条件下也可以不跳闸而正常运行。
In the outdoor temperature is high or the voltage is low, small air-cooled heat pump air conditioners will not stop due to overload and stable operation. The author uses refrigerant bypass and reduce the circulating air volume of the evaporator and other 2 unloading measures to improve the adaptability of air conditioners, that is, the voltage 187V, the outdoor dry-bulb temperature of 48 ℃ conditions can also be normal operation without tripping.
