摘要
选用CSD状态方程、合适的混合法则及其相互作用系数,对替代HCFC-22的三元混合工质HFC-32/HFC-125/HFC-134a进行了热力性质计算误差分析表明计算结果达到一定的精度,在此基础上进行了理论循环计算、分析和比较.
The thermodynamic properties of the ternary mixture refrigerant HFC 32/HFC 125/HFC 134a as a replacement of HCFC 22 have been calculated using CSD state equation, with adequate mixing principle and interacting factors. Error analysis shows the good accuracy of the calculation. Based on the calculated results, the theoretical cycle has been further calculated, analyzed and compared. All of them have been programmed and operated in the computer.
