What is the reason why the freezer is not cooling

It may be that the capillary is blocked and the refrigerant flow does not enter the evaporator. It may also be that the refrigerant needs to be replenished or the refrigeration system is leaking. If the buffer tube inside the compressor ruptures, there may be loose screws or it will cause no cooling. It is also possible that the expansion valve and the discharge valve are not adjusted properly, causing cold air to leak out. Need to check one by one, and then take the medicine.

What is the refrigeration compressor

With the improvement of people's living standards, refrigerator air conditioners believe that everyone is no stranger, they have become a necessity of our family life. But what about refrigeration compressors, how much do you know about it? In fact, refrigeration compressors are widely used in refrigerators, air conditioners and other mechanical equipment. If the refrigeration system is compared to the human body system, the refrigeration compressor is one of the most important components in the refrigeration system, and is the core and heart of the vapor refrigeration system. It sucks the low-temperature and low-pressure refrigerant gas from the suction pipe, and drives the piston to compress it through the operation of the motor, thereby realizing the refrigeration cycle. Next, I will introduce to you what are the precautions for refrigeration compressors and refrigeration compressor maintenance. <img src="{{media url=&quot;magefan_blog/What_is_the_refrigeration_compressor.jpg&quot;}}" alt="" />

Compression refrigerator

A refrigerator that relies on a compressor to increase the pressure of a refrigerant to achieve a refrigeration cycle. Compression refrigerator is composed of compressor, condenser (condenser), refrigeration heat exchanger (evaporator), expander or throttle mechanism and some auxiliary equipment. The compressor is its core equipment.
