排气温度不得超过125℃（距离压缩机150㎜-200㎜的排气管处），但必须比排气压力对应的饱和温度高28℃。

机壳底部中心在保温绝热时的温度不得超过107.2℃，但至少比吸气压力对应的饱和温度高28℃。

电机线圈温度用电阻法测量，测得温度不得超过129.4℃。

吸气温度在户外环境温度高的情况下过热度不小于2.8℃

环境温度至少应在-29℃以上，否则会损坏压缩机。

开机频率为每小时“六开六停”。

The exhaust temperature shall not exceed 125 ℃ (at the exhaust pipe 150 mm - 200 mm away from the compressor), but it must be 28 ℃ higher than the saturation temperature corresponding to the exhaust pressure.

The temperature of the bottom center of the casing during thermal insulation shall not exceed 107.2 ℃, but at least 28 ℃ higher than the saturation temperature corresponding to the suction pressure.

The motor coil temperature shall be measured by resistance method, and the measured temperature shall not exceed 129.4 ℃.

When the outdoor ambient temperature is high, the superheat of the suction temperature shall not be less than 2.8 ℃

The minimum ambient temperature should be at least above - 29 ℃, otherwise the compressor will be damaged.

The maximum startup frequency is "six on and six off" per hour.
