【摘要】 自动复叠制冷系统采用强烈非共沸混合制冷剂,流程中混合制冷剂的分流和汇合是系统关键问题,分流和汇合受不同流量、不同浓度、不同状态等因素的影响。以R600a／R23两级自动复叠制冷系统为例,测量了不同条件下,制冷剂流汇合时温度变化特性,并从理论上进行了分析。更多还原

【Abstract】 Auto-cascade refrigeration system adopted non-azeotrope mixed-refrigerant and the diffluence and blend during the flow are the key problems. They are influenced by different flux, concentration, state and so on . This paper developed and researched auto-cascade refrigeration systems with R600a/ R23. The characteristics of blend refrigerants in the decline of temperature process have been analyzed theoretically.更多还原
