How to deal with the deterioration of refrigeration effect of supermarket freezer
There are many reasons for the deterioration of refrigeration effect of supermarket freezer。When the supermarket freezer
is in use, because there are foods with large moisture in the supermarket freezer or the freezer is opened many times at ordinary times, the inner wall will frost and form a thick ice layer after long-term accumulation. Many people think that the more ice, the better refrigeration. In fact, the opposite is true.
Too much frost will affect the temperature in the supermarket freezer. Because the heat transfer effect of the frost layer is poor, the frost layer exceeding 10mm will seriously affect the refrigeration effect. Therefore, if the refrigeration effect in the supermarket freezer is poor, it is likely that the frost layer is too thick, and the refrigeration effect of the supermarket freezer will return to normal after defrosting.
When the supermarket freezer is in use, do not stack too much inside. There should be space for the placed food, so as to facilitate the normal circulation of air conditioning, so as to achieve the best refrigeration effect.
Supermarket freezers need to be cleaned regularly. For the sealing strip, always scrub it with warm water and then dry it with a dry cloth, which can not only prolong the service life of the sealing strip, but also ensure the tightness after closing the door. If the sealing is not good, the cold air will be lost and the refrigeration effect will be affected.
Daily maintenance is also very important when using supermarket freezers. There should be no heat source around the supermarket freezer, and the ventilation and heat dissipation conditions should be good. The condenser, compressor and other components in the cabinet shall be kept clean. Dust will affect the heat dissipation effect and refrigeration effect.
Generally, as long as the supermarket freezer is used and maintained correctly, the refrigeration effect will not change and affect greatly.
