Study on environmentally friendly refrigerant R13I1/R152a as an alternative for R1 34a in automotive air conditioning system
文献摘要:
Aiming at solving the problem of high global warming potential of R1 34a,a new mixed refrigerant R1 3I1/R1 52a(molar fraction ratio of 35:65)with no ozone depletion potential and low global warming potential was proposed as a substitute for R1 34a in automotive air conditioning.The computational models for the thermodynamic properties of R13I1/R152a were established by using the PR(Peng-Robinson)equation of state combined with the vdW mixing rule.Based on these models,the cycle performance of this working fluid was calculated,which was also compared with that of R134a and R1234yf under the different oper-ating conditions.The results show that R13I1/R152a is a near azeotropic refrigerant whose temperature glide is approximately 0,and the saturated vapor pressure curve of which is equivalent to that of R1 34a.Moreover,compared to R134a,R13I1/R1 52a has an average 5.7%improvement in coefficient of perfor-mance as well as similar volumetric cooling capacity.The average coefficient of performance and volu-metric cooling capacity of R13I1/R1 52a are significantly higher than those of R1234yf by 13.8%and 12.0%,respectively.However,the average discharge temperature of R13I1/R152a is approximately 13.3 K higher than that of R134a,but it is also within reasonable limits.Hence,the application of the pro-posed refrigerant R13I1/R152a in automotive air conditioning system is technically feasible.
