| Abstract: | Compares and analyzes the basic physical character parameters of R32,R410A and R22.Directly charges R32 in R410A unitary air conditioner,and tests the changes of cooling capacity,power consumption,COP and R32 charging quantity.The results indicate that there is a performance optimized point for R32 unit,and when charging quantity is 60% relative to R410A,cooling capacity and COP of R32 unit is maximum and higher than that of R410A unit. |
