1. Check the evaporator of the air cooler regularly to see if the defrosting work is normal. The efficiency of defrosting affects the refrigeration effect and should be paid attention to.
2. Check the working condition of the compressor on time, especially the temperature of the discharged gas. Especially when changing seasons, we should pay attention to the working state of the whole system and adjust the liquid supply and condensation temperature of the system correctly in time.
3. Pay attention to the oil return of the oil level in the compressor and the cleanliness of the oil. When we find that the oil cleaning is too low or the oil level drops obviously, we should solve the related problems in time to prevent poor lubrication and other problems in the later stage.
4. Pay special attention to the running sound of the machine, including compressor, water pump, cooling tower, condenser and fan. If any abnormality is found, it should be repaired in time, and at the same time, pay attention to the vibration of the machine to find the abnormality of the machine in time.
5. Cleaning and disinfection. Cold storage is exposed to all kinds of food and medicines every day, so it must be cleaned and disinfected regularly. Cleaning can remove dirt and bacteria from the surface, and disinfection can kill viruses and bacteria. Cleaning and disinfection should be done by professionals, and professional cleaning disinfectants must be used.
6. Keep the refrigeration temperature. The temperature of cold storage is very important, because it is directly related to the quality and safety of stored items. Check the thermometer in the cold storage regularly to ensure its accuracy. In addition, the temperature of the cold storage should always be kept within the specified range, and once there is any abnormality, measures should be taken immediately to adjust the temperature.
7. Maintain the refrigerated door. The cold storage door is one of the most important parts of the cold storage, and it must be sealed to ensure that the cold air is not lost. Therefore, it is necessary to check the tightness of the refrigerator door regularly to ensure that the hinge and lock of the door work normally. If the door or seal needs to be replaced, it should be replaced immediately.
8. Check the refrigerant regularly. Refrigerant is a substance used for refrigeration in cold storage, and it must be kept at an appropriate level to ensure the normal operation of cold storage. Check the refrigerant level regularly to ensure that they are not leaking or contaminated. If it is necessary to replace or replenish the refrigerant, it should be done by professionals.
9. Check the electrical system. The electrical system of cold storage includes wires, plugs, switches, etc. These devices must be kept in normal operation. Check these devices regularly to ensure that they are not damaged or aged. If it is necessary to replace electrical equipment, it should be replaced by professionals in cold storage.
