The maintenance and management of cold storage mainly revolves around three aspects: start-up, operation management and replacement and frost change. The specific content is as follows:
1. Boot preparation
Before the cold storage is turned on, check whether the valves of the unit are in a normal start-up state
Check whether the cooling water source is sufficient, and after turning on the power, set the temperature according to the requirements.
2. Operation management
Check whether there is any abnormal sound during the operation of the equipment;
Check whether the temperature in the library drops;
Check whether the cold and heat of the suction exhaust are clear, and whether the cooling effect of the condenser is normal.
3. Cold storage ventilation and defrosting
Food preservation cold storage and fruit and vegetable preservation warehouse will release some gases during the storage of goods, and when accumulated to a certain extent, it will cause the deterioration of the goods. Therefore, the cold storage should be ventilated regularly during use, such as once a week. The time is chosen in the early morning when the temperature is low.
Defrosting mainly refers to the defrosting of the cold storage evaporator, when the cold storage is used for a period of time, it is necessary to remove the refrigeration effect of the cold storage in time. When cleaning, cover the storage in the forest library.
Defrosting methods can be selected: electric tube defrosting, water flushing, hot fluoride defrosting, artificial defrosting, hot fluoride defrosting and electric defrosting.
The above is the problems that need to be paid attention to in the maintenance and management of cold storage, and we should analyze specific problems when using cold storage.
