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="" />
