High and low temperature refrigeration units, if unabated warm up, you indicate the emergence of common refrigeration unit failure. But the usual multi-disciplinary staff of electrical equipment can not be free of removable parts. In case of high and low temperature leads to damage again.
1, a refrigerant compressor operating voltage resolution is not stable, as the refrigerant compressor coupled AC contactor does not pull the high-temperature test chamber so the switching power supply may not from here. That is also coupled to the high and low temperature refrigeration compressor cable is not broken or does not couple well. Some high and low temperature conditions in the shipping route in the whole process of short-circuit fault is still there. Then resolved rated working voltage is not in compliance.
2, technical personnel need to distinguish current refrigeration compressor is not normal, the amount of current to exceed the rated voltage refrigeration compressors to work properly, the normal operating voltage if the current amount does not exceed the prescribed, then it indicates a lack of refrigerant. That concept further investigation heat pipe cooling fan is not in normal operation, in the attitude, the wind frequency should be more stable, the wind and the air duct proper symmetry. In this manner also means that the temperature of the refrigerant compressor hand feeling of the stem, the high and low temperature is normally higher, higher than normal temperature as the temperature of the outer air-conditioning fan. Observation Xunhuanjitong centrifugal fan in the room is not working properly, if the work is not burned, not normal air conditioner evaporator volatiles, so as to not desuperheating.
