本文从热力过程分析出发,提出在单级制冷螺杆压缩机中采用两次节流循环来提高动力效率。这对船舶制冷装置尤其是低温工况是非常重要的。
Based on the analysis of thermal process, this paper proposes to use two throttling cycles to improve the power efficiency in single-stage refrigeration screw compressors. This is very important for ship refrigeration equipment, especially for low temperature conditions.
