TY - JOUR TI - Research on quasi-two-stage compression cycle characteristics of refrigeration system for cold storage AU - Yang Fengye AU - Su Zhiyong AU - Wang Chunyan AU - Li Haijun JN - Thermal Science PY - 2022 VL - 26 IS - 3 SP - 2765 EP - 2770 PT - Article AB - In view of the current test methods and evaluation indicators for the performance of cold storage freezing systems, a cold storage experimental platform with a micro-channel heat exchanger is designed using the inject technology, and the power consumption and cooling performance are tested under different conditions of the internal and external environment temperatures, vapor injecting flux, compressor speed, and vapor inject pattern. The experimental results provide us with a useful source for the optimization or improvement of cold storage freezing systems.
