In life, we will not separate freezers and freezers very clearly, freezers and freezers play a role in food preservation, but strictly speaking, freezers and freezers are different:

1 freezer is a kind of equipment used to store a variety of foods that need to be frozen, simple frozen food, large space, mostly horizontal structure, generally for stores or food stores to use, not suitable for family use 2. Freezer is another name for refrigerator and freezer, generally divided into two storage Spaces, one frozen food temperature below -18 degrees, the other temperature between 1-10 degrees for a short time for food preservation, mostly vertical, suitable for ordinary family use 3. The refrigerator has a cold room and a cold room, mostly vertical; 4. Freezers are mostly horizontal, mainly for supermarkets, convenience stores and restaurants and other public places, only freezing function, not suitable for family use of small power, energy saving, environmental protection and energy saving; Air cooling, imported compressor, fast cooling speed; Large capacity, humanized design of storage shelf, goods separation and classification easy to pick up; Unique light box spray painting can be replaced according to customer requirements; Luxurious transparent light box, free to change the picture, all-round three-dimensional display; With roller and adjusting foot design, easy to move and use; Wide climate zone and wide voltage belt double wide design, not affected by region, temperature and voltage, run freely throughout the year, use more secure supermarket freezer defrost the correct steps in the supermarket we will see used for different food refrigeration display freezer, used to put drinks, put fruit, put meat and put ice cream and so on. These refrigerated display cabinets have a good refrigeration effect, while producing many frosts in the process of refrigeration, frost will affect the operation of the supermarket display freezer and the refrigeration effect, therefore, defrosting work needs to be carried out regularly, the following are the correct defrosting steps:

Step 1: Turn the thermostat knob to the "coldest" setting Step 2: Let the refrigerator run for about 20 minutes Step 3: Unplug the power plug Step 4: Open the refrigerator door and place a bowl of warm water on the evaporator Step 5: Close the refrigerator door and repeat the water change several times after a few minutes, until the ice has come off in a large area Step 6: Use a cork spatula to gently remove the remaining frost Step 7: Use a clean towel to wipe all around the supermarket refrigerated display cabinet defrosting to ensure the normal operation of the display freezer, but also effectively save energy, is a very important job! For a long time, the commercial refrigerator condenser cleaning all kinds of refrigerators, freezers, refrigerated display cabinets, and double-door freezers often frost and freeze in the inner part, and if it is not removed in time, it is easy to cause the refrigeration effect of the refrigerated display cabinet.

In general, after the refrigerator is used for a long time, it is necessary to often, and the cycle is usually about seven days to defrost the refrigerator and freezer, so as to improve the refrigeration effect; At the same time, the condenser of the refrigerator and the refrigerator are generally on the steel plate of the cabinet body, so the refrigerator and the freezer should be placed in a well-ventilated position, and the dust inside the refrigerator and the refrigerator body should be wiped in time, so that the condensation effect of the condenser can be improved to achieve the purpose of improving the refrigeration effect and saving electricity; If the refrigerator and freezer are open, the electric fan and air conditioner should be prevented from blowing directly. The night curtain should be closed during non-business hours. The fin of the condenser should be cleaned with a brush every month or so to improve the heat dissipation effect.
