Its properties and performance are similar to R12. The experiment proves that using this ternary mixture in MAC systems the performance is good, we needn’t make too many changes and the replacement work is easier and more convenient than that of R134a. The leakage experiment shows that the leakage of referigerant mixture is not the obstacle to this replacement.展开更多
文摘This paper presents that we can use the new ternary mixture which is acceptable to environment to replace R12 in MAC systems. Its properties and performance are similar to R12. The experiment proves that using this ternary mixture in MAC systems the performance is good, we needn’t make too many changes and the replacement work is easier and more convenient than that of R134a. The leakage experiment shows that the leakage of referigerant mixture is not the obstacle to this replacement.
