What Precautions Should Be Taken When Using a Fresh - keeping Cold Storage in Summer?

2025-01-06

In the hot summer, the use of fresh-keeping cold storage is even more common, as more foods, items, medicines, and biological electronic products require fresh-keeping cold storage to maintain their original quality. Due to the high temperature in summer, the refrigeration system of the fresh-keeping cold storage operates for a relatively long time.

Although the fresh-keeping cold storage operates in a machine - type manner, frequent operation in summer inevitably brings troubles. However, in order to make the fresh-keeping cold storage play a better preservation role in summer, there are many aspects that the cold storage owner needs to pay attention to when using it for preservation.

Heat dissipation of the refrigeration system of the fresh-keeping cold storage: During the operation of the fresh-keeping cold storage, the heat dissipation effect of the radiator of the cold air unit in the cold storage should be checked regularly and in a timely manner. Keep it clean and pollution - free, and clean the surface dust in a timely manner to avoid affecting the heat dissipation effect of the radiator.
Whether the water flow of the water pump in the fresh-keeping cold storage is in a normal state, and whether the cold air fan of the cooling tower is operating normally and rotating forward. Mainly check whether there is a problem of hot air rising.
Check the ventilation space of the air - cooled unit of the fresh-keeping cold storage to ensure that the hot air discharged by the unit can be dissipated in a timely manner. When the ambient temperature is too high, appropriate water spraying on the fins of the radiator can be carried out to help with heat dissipation and improve its refrigeration effect.
However, extreme caution must be exercised to prevent electric shock.
When the fresh-keeping cold storage is operating in summer, the water temperature is also crucial.
For the cooling water temperature of the water - cooled unit, it is best to be below 25°C. If it exceeds this temperature, water should be replenished in a timely manner or the water should be changed and circulated frequently to avoid the influence of too high water temperature on the refrigeration effect.
When using the fresh-keeping cold storage for storage and preservation, the amount of goods stacked in the cold storage must be well - controlled. Especially when stocking goods into the cold storage, the quantity of each incoming shipment should not exceed 30% of the total capacity of the cold storage.
Otherwise, it will bring excessive load pressure to the cold storage, causing the refrigeration unit of the fresh-keeping cold storage to work for a long time and resulting in a slow drop in the temperature inside the cold storage.

Therefore, when using the fresh-keeping cold storage to store items in summer, more attention should be paid to the above - mentioned points and other issues. Then, there is no need to worry too much about some unnecessary problems that the fresh-keeping cold storage may easily encounter in summer.
