The difference between the three types of evaporators dry, flooded, and falling film evaporators

The refrigerant in the dry evaporator passes through the heat exchange tube, and the cold water runs outside the high-efficiency heat exchange tube. Such a heat exchanger has relatively low heat exchange efficiency,

The principle of central air conditioning refrigeration

The principle of central air conditioning refrigeration The liquid Freon enters the evaporator through the capillary. The space suddenly increases and the pressure decreases. The liquid Freon will vaporize and absorb a lot of heat. The evaporator will become cold. The indoor unit fan will remove the indoor air from the evaporator. Blow through, so the cold air blows out from the indoor unit. Let's take a look at the cooling principle of the central air conditioner with the editor for your reference<img src="{{media url=&quot;magefan_blog/The_principle_of_central_air_conditioning_refrigeration.jpg&quot;}}" alt="" />

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="" />

Why does refrigeration equipment particularly emphasize installation

Hidden danger 1: The refrigerant pipe enters dust and impurities<br></br> Dust and impurities in the refrigerant pipeline will cause the effect of the central air conditioner to decrease, increase the wear of the central air conditioner compressor, and cause the central air conditioner to block and affect the cooling effect.<br></br><br></br>
