A theoretical performance study on a traditional vapour-compression refrigeration system with refrigerant mixtures based on HFC134a, HFC152a, HFC32, HC290, HC1270, HC600, and HC600a was done for various ratios and their results are compared with CFC12, CFC22, and HFC134a as possible alternative replacements.
In spite of the HC refrigerants' highly flammable characteristics, they are used in many applications, with attention being paid to the safety of the leakage from the system, as other refrigerants in recent years are not related with any effect on the depletion of the ozone layer and increase in global warming.
Theoretical results showed that all of the alternative refrigerants investigated in the analysis have a slightly lower performance coefficient (COP) than CFC12, CFC22, and HFC134a for the condensation temperature of 50 °C and evaporating temperatures ranging between −30 °C and 10 °C.
Refrigerant blends of HC290/HC600a (40/60 by wt.%) instead of CFC12 and HC290/HC1270 (20/80 by wt.%) instead of CFC22 are found to be replacement refrigerants among other alternatives in this paper as a result of the analysis.
The effects of the main parameters of performance analysis such as refrigerant type, degree of subcooling, and superheating on the refrigerating effect, coefficient of performance and volumetric refrigeration capacity are also investigated for various evaporating temperatures.

的HC冷媒的高度易燃的特点，但它们在许多应用中，注意泄漏的安全支付系统，为近年来的其他制冷剂没有任何有关臭氧耗损的影响层，并在全球变暖的增加。
理论结果表明，在分析调查的替代制冷剂有稍低的性能系数（COP）比剂CFC12，CFC22，HFC134a的为50°C冷凝温度和蒸发温度范围：-30°C和10°C之间。
混合制冷剂剂CFC12和HC290/HC1270（20/80 WT％）CFC22，而不是代替（重量比40/60％）。HC290/HC600a被发现本文中的其他替代品之间的替代制冷剂的结果分析。
性能分析的主要参数，如制冷剂的类型，过冷度，过热对制冷效果的影响，性能系数和容积制冷量也探讨不同的蒸发温度。
