变浓度容量调节空调系统的机理与试验研究

Theoretical and Experimental Research on Air-Conditioning System with VaryingComposition Using Non-Azeotropic Refrigerant Mixtures

在分析混合工质单位容积制冷量随组成浓度变化的特性的基础上 ,结合筛选出的工质R2 2 /R1 4 2b和R32 /R1 2 4 ,进行固定工况下变浓度稳态性能对比试验和变工况变浓度调节稳态性能试验 ,测得空调系统在不同浓度下的稳态性能参数 。

On the basis of analyzing the characteristics of changing refrigerating load by means of varying the composition of non-azeotropic mixture and screening the refrigerant mixtures R22/R142b and R32/R124, the testing methods of fixed experience conditions and variable operating conditions have been carried out.The experimental data of the steady state performance have been obtained.It shows that the capacity control can meet the needs of varying refrigerating load with variable working conditions for the non-azeotropic mixtures.
