Everyone in the process of using commercial refrigerators, there will be unavoidable small problems, but do you know that the problems of commercial refrigerators may be false failures?
During the use of the freezer, various failures are not caused by the problems of its own parts and components.
When the commercial refrigerator is overhauled, these false faults must be eliminated before the overhaul can be carried out smoothly. Let's analyze what are the common false faults of commercial refrigerators.
1. The refrigeration effect of commercial refrigerators becomes worse
Improper use of commercial refrigerators, unsuitable placement, poor ventilation, and excessive dust accumulation in the condenser and not being cleaned in time will cause poor heat dissipation of the condenser and worsen the cooling effect of the refrigerator.
2. Extend the boot time
Excessive storage of food in commercial refrigerators hinders the circulation of air-conditioning and causes the temperature in the cabinet to become higher. At the same time, if the freezer door is opened frequently, the compressor startup time will inevitably be prolonged.
3. The icing phenomenon of commercial refrigerators is serious
Commercial freezer freezers do not frost and freeze. This phenomenon indicates that there is too much moisture in the freezer and the temperature is too high. The moisture may come from food or may be related to the excessive number of door openings. This phenomenon is more likely to occur in single-door freezers.
The solution is to remove the ice on the surface of the freezer first, and then adjust the temperature controller to lower the temperature in the freezer.
4. There is a sound of water flowing in the commercial freezer
The sound of water flowing in the cabinet is produced when the commercial refrigerator is working. This is the movement of the refrigerant in the pipeline. When it flows to the evaporator, its state is liquid. When the liquid refrigerant flows, it will make a clear sound of flowing water. Can be heard. This is caused by the inertia of the refrigerant movement and is a normal sound.
5. Heating phenomenon of commercial refrigerators
When the commercial refrigerator is working normally, the shell generates heat, and the heat absorbed by the evaporator in the cabinet and the heat generated by the compressor during operation are all dissipated through the condenser located outside the refrigerator.
At present, some condensers are located behind the freezer, and some are hidden on both sides of the box. Under normal heat dissipation, the surface temperature of the condenser can reach 50°C to 60°C. Therefore, it is normal for the shell of a commercial freezer to heat up.
6. Applicable voltage for commercial refrigerators
According to the national standard, the allowable range of the voltage of the freezer is 187V to 242V. Insufficient power supply voltage or poor contact between the plug and the socket may cause the voltage applied to the commercial refrigerator to be lower than the operating voltage, and the refrigerator does not start or starts frequently. When the voltage fluctuates too much, it is best not to use it.
