What will be the impact of commercial refrigerator refrigeration

Part of the reason for the poor refrigeration of the refrigerator is the problem of the components of the refrigerator itself, and the other part is caused by the damage of the refrigerator during use and the improper maintenance of the refrigerator.


Which parts of the refrigerator affect the refrigeration effect

1. The reason for the poor refrigeration effect of the refrigerated cabinet: poor sealing performance results in a large loss of cold capacity in the refrigerated cabinet and poor refrigeration effect. The airtightness is mainly the door sealing strip, so when buying a medicine refrigerator, it is necessary to check whether the refrigerator door is uneven or uneven. If the seal is not tight or the door is frequently opened and closed, the refrigerated cabinet will directly increase the loss of large cooling capacity. Try to avoid opening the door to prevent a large amount of hot air from entering. When the door is opened frequently or the purchase quantity is too large, the heat load increases sharply, and it generally takes a long time to cool down to the specified temperature.

2. Poor refrigeration effect of vertical refrigerators: the thickness of the insulation layer is not bad, and the insulation performance is poor, which is caused by improper selection of the thickness of the insulation layer during the design of the main refrigerator or poor quality of insulation materials. The use environment of the refrigerator may cause the insulation layer to be damp, deformed, or even eroded, and its thermal insulation capacity will decrease, the loss of cooling capacity will increase, and the temperature drop will be significantly slowed down.

Reasons for improper maintenance of refrigerators

1. The frosting problem of the refrigerator is not dealt with in time, resulting in too thick frost or excessive dust on the surface of the evaporator, which reduces the heat transfer effect. Since the surface temperature of the freezer evaporator is mostly lower than 0°C and the humidity is relatively high, the moisture in the air is very easy to frost or even freeze on the surface of the evaporator, which affects the heat transfer effect of the evaporator. In order to prevent the frost layer on the surface of the evaporator from being too thick, it needs to be defrosted regularly.

2. The compressor and condenser of the refrigerated cabinet are important refrigeration components. If dust is stained, it will affect the heat dissipation, which will shorten the service life and directly affect the refrigeration effect. Regular cleaning and maintenance. The condenser fins of the refrigerated cabinet should be every other month. Clean the left and right brushes once to improve the heat dissipation effect.
