Fellow teachers, everybody is good;It has encountered a problem and also hope that the teacher can give a hint, a space BCD-212 refrigerator evaporator leakage (pipe only the freezer frozen check no leakage test machine has not changed) effect is not too obvious not cold freezing is not too good, suspected problem (then check the condenser when the condenser with black powder was something like Mu Hu love tools played in the compressor, compressor oil has yellow black) changed or not just starting line, about more than and 10 minutes of compressor on the burning and then protect the freezer is about 4 meters 2 meters refrigerant 600A capillary tube, please peer thanks a lot!!!
This is only a problem of compressor, is a circuit cause the compressor to geothermal, two is installed inside the compressor itself questions lead to overheating protection, the refrigerator is not cooling there are two major problems, one is the heat is not good, to solve the problem of heat dissipation is itself or on both sides of the refrigerator condenser and cooling place (including compressor) placed ventilation where is the two refrigeration system with micro leakage place, mainly in the normal compressor rotation, without refrigeration, it only can overhaul inspection, the compressor and refrigeration system from him. Refrigeration system pressure, leakage, two is the compressor after the startup belly with your fingers will hold the inlet and outlet of compressor, obvious pressure discharge, or apparent suction suction, you know there is no fault of the compressor,
Look at the system pressure is certainly too high pressure into the compressor overload operation, check the fan has not started, there is no capillary block.
