What to do if the vending cabinet is not cooling

I believe everyone is no longer unfamiliar with this product of automatic vending cabinet. With the gradual development of the times, people have gradually become familiar with and recognized this industry. In recent years, with the continuous increase in demand, the development of the industry is also thriving. Many people have chosen this industry as their entrepreneurial direction, and the number of unmanned micromarkets and vending cabinets has also increased sharply. However, as the number of machines is large, and the use time is long, many problems will arise, such as jams and no cooling. So what should I do if the vending cabinet is not cooled? If there is water in the filter of our vending cabinet, we need to open the back of the tube or change the tube. If there is no moisture in the zero-pressure filter, the door pipe is generally rusty and the perforation is large. We also only need to remove the door pipe or the external condenser. In addition to the above, if the machine cannot be cooled, we can also plug in the power supply and listen to whether the compressor makes a sound when it is running. If we hear the compressor running sound, then we can turn on the refrigerating room again. Door, listen to its voice. If it is a crisp gurgling sound, it means that there may be no refrigerant in it, and we need to add refrigerant. If it is a hissing sound, it may be a high-pressure leak, and then we touch the outlet of the capillary tube again, if it still has A hint of coolness means that there is still some refrigerant in it, and it may be a low-pressure leak. If there is a hissing sound in the vending cabinet at the beginning, there is still a little bit of refrigerant, after a week or even a month, there is still refrigerant, but there is no cooling, there is the sound of the compressor running, which is very stuffy, and then again If there is no other sound, then it can be confirmed that it is an ice block. In the case of an ice block, we can stop the deicing and refrigerate again. If the machine does not produce ice leakage, but this phenomenon occurs again, in this case, it may be cold storage or temperature change. If the machine makes a grunting sound, then we can check whether there are any traces of water flowing through the door of the vending cabinet, and whether the middle door cabinet is rusty. If there is, then we can basically conclude that it is a high-pressure leak. . At this time, if you can find the door tube, you can throw the door tube directly, if you can't find it, you need an external condenser. All of the above are preliminary judgments based on the sound produced by the vending cabinet. The specific situation should also be judged in conjunction with the pressure and the state of the filter. That's it for this time, see you next time.
