摘　　要：从热力学第一定律出发,对蒸气压缩制冷循环进行了能量分析,给出了蒸气压缩制冷循环的能量平衡模型和能量平衡方程。依据蒸气压缩制冷循环的理论分析和实例计算,探讨了提高蒸气压缩制冷循环能量效率的途径。结论表明,通过改善热交换器的传热性能,改造制冷循环过程,合理设计和匹配压缩机,正确选择制冷剂,降低动力设备的能耗,加强运行管理和设备管理的自动化都能提高蒸气压缩制冷循环的能量效率。Based on the first law of thermodynamics, the energy of vapor compression refrigeration cyclewas analyzed. The energy-balance model and the energy-balance equation were developed. According to theoretical analysis and examples for vapor compression refrigeration cycle, the ways to im-prove the energy efficiency of vapor compression refrigeration cycle were investigated. Conclusions show that the energy efficiency for vapor compression refrigeration cycle has been increased by improving the heat transfer performance of heat exchanger, transformimg the refrigeration cycle, rationally designing and matching the compressor, correctly choosing the type of refrigerant, reducing the energy-consumption of power equipment and strengthening the automation ofoperation management and device management。
