2024-03-28
1. Refrigerant leakage; leakage caused by electrical (line, body) insulation damage, etc.
2. Parts are stuck: For example: compressor is stuck, fan is stuck, bearings of moving parts are stuck, etc.
3. Parts damage: refers to the supermarket cake cabinet compressor valve damage, piston hair, fan blade fracture and various parts damage.
4. The original was burned: burned cake cabinet compressor motor windings, fan motor windings, solenoid valve coils, relay coils and contacts.
5. Line disconnection: including electrical line disconnection; fuse fusing; contact disconnection of overload protector due to overheating or excessive current; contact disconnection of pressure relay due to abnormal pressure of refrigeration system.
6. Dirty blockage and ice blockage: dirty blockage and ice blockage of the refrigeration system of the cake cabinet; air filter blockage; air inlet and air outlet are blocked by obstacles; compressor refrigeration oil is black, upper and lower bearing sleeves fall off or wear, The connecting rod is broken, the friction surface of the crankshaft and the bearing and the friction surface of the crankshaft and the connecting rod have galling marks, the motor rotor has wear marks, and the suction and exhaust valve plates are intact.
The amount of frost inside the cake cabinet is related to the size of the humidity inside the box. The frost on the inner wall of the cake cabinet is not as much as possible, but as little as possible, because the heat transfer coefficient of the frost is low. If the thickness of the frost layer exceeds 10mm, the cooling effect will obviously decrease. Therefore, when it is found that the thickness of the frost layer on the inner wall of the cake cabinet will exceed 10mm, it should be defrosted.
