Again, defrost heater can be inhibited in the surface temperature of a flammable refrigeranttemperature below the ignition.
再有，可将除霜加热器的表面温度抑制在可燃性制冷剂的发火温度以下。
2
Refrigeranttemperature and pressure that affect the level of refrigerant charged must be periodically managed and recorded.
影响被充电的冷冻剂的水平的冷却液温度和压力必须周期性地处理和记录。
3
The high-pressure liquid refrigerant through the expansion valve, because the expansion valve throttling pressure drop, the refrigerant into normal temperature low pressure liquid.
