According to the results of simulation of the new cycle using R12 and the alternatives R152a, R134a, R22/R152a as refrigerants, a significant profit in COP and volumetric refrigeration capacity relative to the simple vapor-compression cycle is obtained.

• 以R12以及它的可能替代物R152a、R134a、R22/R152a等作为制冷剂的模拟计算结果表明:新循环性能系数COP及容积制冷量较原蒸汽压缩循环有明显提高。
