What is maintenance order of repairing dehumidification of dehumidifier
I. ventilation system failure of Dehumidifier:
1. inlet and outlet grates: a. man-made damage or aging cracks; B. severe obstruction of the air intake or egress;
2. air filter net: be blocked or damaged by dust;
3. evaporator: a. evaporator condenser fin; B. icing on the evaporator surface;
4. fan motor: a. the capacitor is damaged; B. fan motor holding shaft; C. rotor and shaft loosening; D. bending deformation of the shaft; E. damage to the bearing; F. winding down of winding;
5. fan: a. loosen the fixed screw; B. deformation or damage to fan blades; C. fan blade dust serious, seriously affect the air volume; D. the small type Dehumidifier fan also has the phenomenon of the fan blade caused by the dust accumulation.
Ii. breakdown of electrical system of dehumidifier:
1. compressor and fan are not transferred: a. power supply is cut off; B. the switch is not closed; C. disconnect socket; D. low voltage; E. circuit breaker disconnect; F. the insurance tube is burnt.
2. compressor does not turn, fan: a. initiator fault; B. capacitor failures; C. overload protection.
3. compressor and fan operation: failure of refrigeration system.
Iii. breakdown of the refrigeration system of the dehumidifier:
1. total leakage of refrigerant;
2. blocking of refrigeration system: a. dirty; B. oil plug; C. welding plug welding;
3. excessive refrigerant;
4. no displacement ( fault ) of the compressor.
Iv. compressor failure of dehumidifier:
1 、 bad compression, high and low pressure chamber channeling gas;
2. damage to the operation piece, compressor holding shaft.
