The heat exchange process relies on sensible heat to complete, at which point the high-pressure heat exchanger is called a gascoolerThis is also the most popular cyclic method in current research. This not only avoids the system performance degradation caused by high heat source temperature under subcritical cycle conditions, but also has great advantages in flow and heat transfer due to the special physical properties of fluids under supercritical conditions.

The process of CO2 transcritical refrigeration cycle is slightly different from that of ordinary vapor compression refrigeration cycle. At this time, the suction pressure of the compressor is lower than the critical pressure, and the evaporation temperature is also lower than the critical temperature. The heat absorption process of the cycle is still under subcritical conditions, and the heat exchange process is mainly completed by latent heat. However, the discharge pressure of the compressor is higher than the critical pressure, and the condensation process of the working fluid is completely different from that in subcritical state. The heat exchange process relies on sensible heat to complete. At this time, the high-pressure heat exchanger is no longer called a condenser, but a gas cooler.

The various types of air heat exchangers, radiators, surface coolers, and coolers produced by Wuxi Hongsi Xin Heat Exchange Equipment Co., Ltd. have been widely used in industries such as metallurgy, mining, petroleum, chemical, power, and medicine.
