Problems solved by technology

In this refrigeration system, the cold-end gas and the heat-exchanged hot-end gas are directly combined and introduced into the condensing evaporator. Part of the cooling capacity of the cold-end gas has not been fully utilized, which is not conducive to the improvement of the refrigeration efficiency of the refrigeration system.
In addition, this patent also has a rectification device, which increases the complexity of the system

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a self-cascading refrigeration system with low-temperature function. Background technique [0002] With the rapid development of social economy, people's demand for refrigeration equipment increases accordingly. In the traditional refrigeration compression refrigeration system, as the refrigeration temperature decreases, the throttling loss of the throttle valve increases, so the performance of the refrigeration system decreases. [0003] The vortex tube is a device with simple structure and energy separation characteristics. The energy separation phenomenon of the vortex tube was discovered by French metallurgical engineer Ranque and applied for a US patent in 1932. In 1933, he gave a report on the vortex tube device and its vortex temperature separation effect at the French Engineering Thermophysics Conference. The results of the research on the refrigeration and heating mechanism of...
