Detailed Description of Single-Stack Refrigeration Technology

With the continuous development of the times, ultra-low temperature refrigeration technology is also constantly developing. On the list of ultra low temperature freezers, Wuxi Guanya continues to advance in the refrigeration equipment market with the advantages of its own single-stack refrigeration technology. So what is a single-stack refrigeration technology? What is the difference between the previous multi-stage compression refrigeration technology? What is the difference between it and the previous multi-stage compression refrigeration technology?

The difference between a single-stack refrigerator of ultra low temperature freezer and a multi-stage compression refrigeration:

Although the evaporation temperature achieved by a compression refrigeration cycle of a single-stack refrigerator is lower than that of a single-stage compression refrigeration cycle, it is limited by the physical properties of the refrigerant and the characteristics of the compressor operation. However, due to the limitations of the physical properties of the refrigerant and the characteristics of the compressor operation, when the evaporation temperature is lower, the multi-stage compression refrigeration cycle often fails to meet the requirements. At this point, a single-stack chiller refrigeration cycle is required.

Multi-stage compression technology is now widely used in the refrigeration industry. For example, the two-stage compression and three-stage compression of the centrifugal centrifuge greatly improve the performance of the unit, and the COP value can reach 7.0; The twin-screw compressor can increase the temperature of hot water during winter heating  to 80 °C by applying the two-stage compression technology, which broadens the application range of the heat pump unit; The two-stage compression technology of the scroll compressor can make the environment temperature of heating multi-link mechanism below minus 25 °C.

The principle of single-stack refrigeration technology of ultra low temperature freezer:

The chiller of the Wuxi Guanya ultra-low temperature freezer in the ultra-low temperature freezer list is usually composed of two separate refrigeration systems, they are called high temperature and low-temperature parts, respectively.

The medium temperature refrigerant is used in the high-temperature part, and the low-temperature refrigerant is used in the low-temperature part. The evaporation of the refrigerant in the high-temperature part system is used to condense the refrigerant in the low-temperature part of the system, and the two parts are connected by a condensing evaporator, which is both the evaporator of the high-temperature part and the condenser of the low-temperature part.

The refrigerant in the low-temperature part absorbs heat (ie, to produce cold) from the cooled object in the evaporator, and this heat is transferred to the refrigerant in the high-temperature part. The heat is then transferred to the cooling medium (water or air) by the refrigerant in the high-temperature part.

From the above point of view, Wuxi Guanya's refrigeration technology in the ultra-low temperature freezer list is produced by years of research and development in the technical department, and has a special after-sales department to guide, which is more safe and reliable.

Lneya has the best ultra low temperature freezer price.
