If the commercial refrigerators and freezers are not used for a long time, first, it will cause odor and mold in the body box; Second, it may accelerate the aging and discoloration of the liners of commercial refrigerators and freezers, so that regular maintenance is needed. If refrigerators are not used for a long time, it is better to start the "holiday" mode. If this function is not available, it is recommended to unplug the power supply, clean the refrigerator with water and a little detergent, then open the door of the commercial refrigerators and freezers for air drying, so as to keep the refrigerator away from odor or mold. The following method is applicable to most commercial refrigerators and freezers in the market, including 2 glass door commercial refrigerator and 3 glass door commercial refrigerator.
If refrigerators are not used for a long time, then it is best not to keep the items in the commercial refrigerators and freezers. You would better eat as many things as you can, otherwise moldy things will turn the refrigerator into a "green" home appliances. After the items are sorted out, you can spend a little time to defrost the refrigerator, and of course, except the frost-free refrigerator. Then wipe the refrigerator with a clean cloth. Before the next use, the first thing to do is open the refrigerator door to ventilate, and at the same time wipe the inside of the refrigerator again. If the refrigerator is using the back-hanging condenser, then it is better to clean dust in the condenser, so as to facilitate the heat dissipation of the refrigerator after work.
If refrigerators are not used for a long time, do not forget to unplug the power supply ahead of time. It's better to switch off the power during the operation intervals of the commercial refrigerator and freezer so as to prevent damage to the compressor and other components. Before continuing to use, clean the commercial refrigerators and freezers and do not use it immediately. It is best to let the refrigerator run for a short time. After running every two or three minutes it should be stopped for a period of time, which should be repeated for several times. Why would you do that? As we know, the lubricating oil is fluid, and when it is left in the refrigerator for a period of time, part of the lubricating oil will become too thin. When used again, because the internal temperature of the refrigerator is the same as the room temperature, the continuous operation for a long time of the compressor is needed to reduce the temperature to the rated temperature. At this time the too thin part of the lubricating oil will occur rapid wear, thus reducing the life of the refrigerator. Allowing the refrigerator to run for a short time repeatedly enables the lubricating oil to be redistributed within the compressor and to infiltrate the machine parts in the intervals.
It should be noted that if the newly purchased commercial refrigerators and freezers have been sitting in storage for some time, in the first use the method can also be used to maintain the refrigerator, in order to ensure the compressor a long service life.
