What is the reason that the copper pipe in the freezer is frost free?
1, freezer does not stop, may be your temperature setting is too low, it is possible to open the freezer switch, but also may be your thermostat is broken;2, the trachea slightly frost or condensation is normal, usually after the compressor stops, will defrost evaporation. But since your freezer doesn't stop, there is no defrosting.
Mostly because of the refrigeration system of refrigerant has a certain degree of leakage or freezer freezes caused by too much, depending on what parts of the copper tube and frosting the compressor suction exhaust temperature to determine.When the refrigeration system of the pipeline due to abnormal situation and the occurrence of partial leakage of refrigerant, refrigeration capacity of refrigeration system decreased overall, the temperature in the freezer can not reach the set temperature, evaporating pressure in the pipeline to reduce the local system, will lead to pipeline local frost even ice compressor running.When the local heat exchanger in the freezer is seriously frozen, the evaporation capacity of the system is seriously reduced. The refrigerator can not reach the set temperature, and the liquid refrigerant can not be effectively evaporated. This will also happen.Suggested handling:1, freezer broken electrochemical ice, drain all the ice water, and with a clean towel dry moisture, re energized, turn on, observe the refrigerator operation is normal;2, if the freezer evaporator pipe in the first half of ice, frost, and the latter half of the clean, it is necessary to find professional maintenance personnel on-site overhaul, to see whether the system refrigerant enough.
