Problems solved by technology

However, in these cycles, a single ejector is used to recover part of the expansion work of the throttling process, and thus has limited ability to improve system performance
In addition, in the traditional vapor compression refrigeration cycle system, although the compressor suction heat recovery is also used to improve the performance of the refrigeration cycle system, most of the useful energy is still not fully utilized.
