For the problem of poor cooling performance of the fresh-keeping cabinet, I believe that most shopkeepers who use the fresh-keeping cabinet will encounter it. Then there are four reasons for this kind of problem. Let's first understand these four problems, and then check to see where the problem is.

1. The thermostat does not stop working, resulting in unlimited cooling of the chiller. Zui will eventually burn out due to the defrosting of the evaporator of the fresh-keeping cabinet.

2, if it is not ice blocking, it can not be ruled out that the cooling fan leaves are broken, it is likely that too much food is accumulated in the tuyere to reduce the cooling effect.

3, may be a problem in the temperature setting, the temperature of the fresh cabinet should be set lower in the summer, and the temperature in winter is set slightly higher. If you switch the freezer door frequently, or if there are too many things stored in the fresh-keeping cabinet, the refrigeration effect of the fresh-keeping cabinet will be poor. The reasons for the poor cooling effect of the fresh cabinet are those

4, the problem of fresh-keeping cabinet compressor, if the fresh-keeping cabinet does not cool, but exclude the above two possibilities, then the rest is the problem of the fresh-keeping cabinet compressor, the way of inspection is to remove the return air pipe, use the fingers to block the exit, The compressor is then turned on, and if the pressure displayed by the compressor is too low, there must be a problem with the compressor. During the use of the cabinet, its working time and power consumption are greatly affected by the ambient temperature, so we need to choose different gears in different seasons.

Reasons for poor cooling effect of fresh cabinet

In the refrigeration system, the refrigerant in the fresh-keeping cabinet uses the heat in the refrigerator during the liquid gasification process, and transfers the heat to the surrounding environment under the action of the refrigeration compressor. If the refrigerator has a leak in the refrigeration system due to improper welding or improper use, the refrigerant in the refrigeration system will all leak out for a certain period of time. Without refrigeration, there is no way to achieve refrigeration.

In this case, please ask the professional to carefully check and repair the leak point, then vacuum dry and refill the qualified amount of refrigerant. The cooling method is to cool the food by natural convection of cold air. If the original cleaning work in the refrigeration system is not thorough, after a period of operation, the dirt will be blocked in the copper mesh or capillary of the filter. The sound of the airflow can not be heard with the ear close to the evaporator, and the heating at the exit does not work. This indicates that the system is clogged and should be excluded by professional technicians. If you need a freezer, fresh cabinet, showcase, air curtain cabinet, etc.
