摘　　要：报道了吸收制冷系统中 R2 2 / DMF、R134a/ DMF和 R134a+R32 / DMF( R134a和 R32分别以 1∶ 1和 3∶ 7摩尔比混合 )等四种工质对的实验结果 ,并进行了比较和分析。结果表明 ,混合制冷工质对 R134a+R32 ( 3∶ 7) / DMF在工作压力比 R2 2高出 2 0 %的条件下 ,其系统性能与工质对R2 2 / DMF相当。This is an experimental study aiming to evaluate system performances of the most credited fluids which are likely to substitute for R22/DMF in absorption refrigerating systems.The working pair R22/DMF,R134a/DMF and R134a+R32/DMF,whose refrigerant was mixed by different ratios,were tested on our experimental set up.The results show that the working pair R134a+R32/DMF(R134a:R32=3:7by mole),whose working pressure was 20% higher than that of R22/DMF,has performances very close to those of R22/DMF.
