Sharing tips on repairing commercial refrigerators that are not cold enough

Usually commercial refrigerators in catering institutions run 24 hours a day to ensure the freshness of the ingredients. Commercial refrigerators of this type that are used intensively should be cleaned and maintained regularly. This can effectively reduce their failure rate and also play a role. Energy saving effect. For example, Junhong electrical maintenance personnel received a call from a customer before. The problem the customer encountered was that the temperature of the commercial four-door refrigerator was getting higher and higher. Because the refrigerator was full of fresh ingredients, the customer was very anxious, so Junhong personnel came to the door immediately. repair.

After arriving at the store, the maintenance staff first checked the condenser screening program of the refrigerator and found that a large amount of dust and dirt accumulated on the screening program, which caused poor air circulation and affected the condensation efficiency. In order to restore normal operation, the maintenance staff cleaned the screening program and checked the entire condensing system to ensure that there were no other obstructions. After cleaning, the cooling capacity of the refrigerator was significantly improved, and the internal temperature began to fall back to the normal range. Then, while the refrigerator was operating After the maintenance was stopped, Junhong's maintenance personnel checked the refrigerant in the compressor and talked with the boss and learned that this four-door refrigerator had not added refrigerant for two years, so Honeywell R-1234yf refrigeration was added to it. agent, and then turn on the power again, the cooling effect of the commercial refrigerator becomes obviously better.

Like the commercial four-door refrigerator mentioned just now, it is very common for the temperature to get higher and higher. This type of large commercial refrigerator basically runs 24 hours a day, and if it is not cleaned and maintained, it is easy for the filter to become clogged. Junhong also encountered a situation where the compressor of a commercial refrigerator failed. This type of refrigerator not only showed poor cooling effect and an increase in temperature. Another obvious phenomenon was that the refrigerator with a faulty compressor ran very loudly. Therefore, you should pay attention if you find that the refrigerator is very loud when you use it daily.

What I have shared above is how to troubleshoot the problem of increasingly high temperatures in commercial four-door refrigerators. In most cases, it is due to compressor and screening program or condenser failure. If the cooling gradually deteriorates, it is because of the cooling problem. If the agent is insufficient, once you master these, you can quickly solve this kind of problem.
