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.

Abstract

The invention discloses a dual-jet and dual-backheating combined synergistic refrigerating cycle system for a dual-temperature refrigerator. The dual-backheating combined synergistic refrigerating cycle system for the dual-temperature refrigerator is characterized by comprising a compressor, an exhaust backheating device, a condenser, a suction backheating device, a first capillary tube, a second capillary tube, a refrigerating chamber evaporator, a first injector, a second injector, a freezing chamber evaporator and a gas-liquid separator. By the adoption of the dual-backheating combined synergistic refrigerating cycle system for the dual-temperature refrigerator, expansion work and useful energy which are generated in the process of throttling can be fully recycled and utilized, and the efficiency and the performance of the refrigerating cycle system for the dual-temperature refrigerator are remarkably improved.
