How to use a commercial freezer, introduction to the skills of using a commercial freezer

Freezer products are used more in shopping malls, especially now that summer is coming, freezers in shopping malls are even more important. For the quality of home life, we cannot do without freezers. Freezer products are indeed very important, and you may buy freezer products, but do you pay attention to some things when using commercial freezers?

Keep away from heat sources: It should be placed in a place away from heat sources and protected from direct sunlight. Due to the need for heat exchange with the outside world during work, it is necessary to dissipate heat to the outside world through the condenser. The higher the ambient temperature, the slower the heat dissipation, which will make the refrigerator and freezer work longer, increasing power consumption and poor cooling effect.

It should be placed in a place with low humidity: Since refrigerators, freezer shells, condensers and compressors are all metal materials, if the air humidity is too high, these parts will rust and shorten the service life of the refrigerator. At the same time, humid and overheated environments can cause condensation on the surface of the refrigerator and affect the performance of electrical appliances.

It should be placed in a well-ventilated place: if the refrigerator and freezer are filled with debris, or too close to the wall, it is not conducive to heat dissipation and will affect the cooling effect. There should be at least 30CM of space on the top surface of the refrigerator, and at least 10CM of space on the back and sides to facilitate heat dissipation.

It should be placed on a flat and solid ground: and keep the compressor level. This is not only necessary for safety, but also allows the compressor to work smoothly, reducing vibration and noise.

In summer, the room temperature is higher. In order to reduce the temperature in the house, some users open the door of the refrigerator and let the cold air in the box run out to reduce the indoor temperature. This practice is harmful. According to the laws of thermodynamics, during the refrigeration process of the refrigerator, the heat of the condenser is the sum of the heat absorbed by the evaporator and part of the energy generated by the operation of the compressor. The room temperature cannot be reduced but rises. In addition, if the refrigerator is opened for a long time, a thick frost layer is easily formed on the surface of the evaporator. Continuous operation of the compressor will also cause overheating and burning, which will seriously affect the service life and performance of the refrigerator.

Refrigerators use the method of lowering the temperature to inhibit the reproduction of microorganisms in food, catalyze enzymes and reduce the oxidation rate of food, but low temperature cannot completely kill microorganisms and prevent enzyme catalysis and food oxidation. Many microorganisms can grow slowly in a low temperature environment below 0 ° C. With the extension of storage time, food will also spoil and deteriorate. Therefore, food stored in refrigerators should not exceed the storage period of food.

The precautions for commercial freezers are introduced here. I hope the introduction of the editor can help you have more understanding and methods in the maintenance of commercial freezers. I also hope that when using commercial freezers in the future, you can pay attention to all aspects and use them carefully. This will also be of great help to the service life and quality of commercial freezers, so it is also necessary for everyone to understand the maintenance knowledge of commercial freezers.
