Today commercial refrigeration equipment is using new refrigerants such as R290, R600a, etc. These refrigerants have a higher risk factor. Therefore the danger for the after-sales service personnel can happen at any time. Besides the safety factor, another important reason is the inconvenient and costly after-sales service. Based on these problems, Miracle proposes a fireless …

The difference between the saturated liquid temperature corresponds to the condensing pressure of the condenser and the actual temperature of the liquid at the condenser outlet. In engineering, the exhaust pressure is generally approximated as the condensing pressure. And the difference between the saturated liquid temperature corresponding to the exhaust pressure and the temperature of …
If you want to know the reason for the high degree of supercooling, you should first know what is the degree of supercooling? You also can check this video to learn more. The liquid temperature reaches the theoretical crystallization temperature and can not be crystallized. But must be below its temperature at a certain temperature …
Important references for choosing a compressor are energy consumption and reliability. Therefore it is very important to choose a compressor that suits your needs. Low energy consumption and less frequent maintenance can directly bring you more profit. Of course, this also depends on the commercial compressor standards in each region. You can in here know …

Refrigeration system superheat is the actual temperature of the refrigeration valve or other media that is a few degrees higher than the saturation temperature corresponding to the actual stresses, called superheat. For example 1atm atmospheric pressure, 110 overheated water vapor its superheat degree is 10 degrees. The superheat of the refrigeration system and air conditioner system is …
Centrifugal compressor is a vane rotary compressor with a balanced operation, reliable operation, high running rate, fewer friction parts, less maintenance cost, less personnel, and other characteristics. With the achievement of gas dynamics research to make the efficiency of centrifugal compressors continue to improve. Coupled with the high-pressure seal, small flow narrow impeller processing, multi-oil …
The concept of compression ratio, over-compression, and under-compression The compression ratio of a compressor is theoretically the ratio of the absolute discharge pressure to the absolute suction pressure. For example, if the absolute exhaust pressure is 20 bar and the absolute suction pressure is 5 bar, then the compression ratio is 4. There are also …
In the refrigeration industry compressor brand rich, in the huge market demand, refrigeration and air conditioning compressors still abide by the law of two or eight. Eighty percent of the market share is controlled by a few refrigeration compressor manufacturers, such as Danfoss, Copeland, and Bitzer. This has both advantages and disadvantages for the HVAC …
