提出一种压缩／喷射混合制冷循环，该循环相对蒸气压缩制冷循环改动较小，易于实现．针对此循环进行了理论分析和计算，并与相同工况下的简单蒸气压缩制冷循环作了比较．对７种不同制冷工质讨论了喷射器喷射系数及其效率对循环性能的影响，分析了变工况条件下循环性能系数ＣＯＰ的变化．计算结果表明，新循环能有效地提高循环性能系数．
A compression / injection hybrid refrigeration cycle is proposed that is relatively easy to change with respect to the vapor compression refrigeration cycle. The theoretical analysis and calculation for this cycle are made and compared with the simple vapor compression refrigeration cycle under the same operating conditions. The influence of ejector injection coefficient and its efficiency on cycle performance was discussed for seven different refrigerant refrigerants. The variation of COP of cycle performance under varying working conditions was analyzed. The calculation results show that the new cycle can effectively improve the cycle performance coefficient.
