7. What are the precautions for fresh-keeping cold storage?

1. Maintenance of sealing parts of fresh-keeping cold storage. Because the fresh-keeping cold storage is composed of several heat insulation boards, there is a certain gap between the boards. During construction, these gaps will be sealed with sealant to prevent air and moisture from entering.

Therefore, some parts with seal failure should be repaired in time during use. 2. The electrical equipment of fresh-keeping cold storage equipment should be protected from moisture, so as to avoid electric shock caused by leakage.

3, often check and confirm whether the voltage of the power supply meets the requirements, the voltage should be 380 V 10% (three-phase four-wire system). When the cold storage equipment is not used for a long time, the main power supply of the fresh-keeping cold storage should be cut off, and the cold storage equipment should be ensured not to be polluted by moisture, dust and other substances.

4. For example, filming inspection can also be carried out below, which also brings great convenience. 5, all refrigerant pipe insulation pipe must be bandaged, steel casing should be used when crossing the floor.

6. Regularly check whether the connecting pipes of the refrigeration unit and the connecting pipes on the valve parts are firm and whether there is refrigerant leakage (generally, there will be oil stains where leakage occurs). The most practical leak detection method is: dip sponge or soft cloth in detergent, rub it and foam it, then evenly spread it on the place to be detected and observe it for a few minutes.

If it leaks, bubbles will appear. Mark the leak, and then fasten or gas weld it (inspected and repaired by professional refrigeration personnel).
