Dear Friends,

First of all, Thanks for participating in my questions.

Suppose that one compressor can work with R22 and R404A both of them.
As we know in same situation (Same evaporator and condenser pressure and temp.) Cp of R404A is higher than R22 and we see on catalogues that Capacity of compressor with R404A is higher than R22.

But at Maneurop (Danfoss) compressors I saw that capacity of compressor (in same evp. Temperature) at Tcondenser 30 & 40 with R404A is higher than R22 but at Tcondenser = 50C capacity of compressor with R22 is higher than R404A !

Does it have any explanation ? Why at Tcondenser = 50C this time capacity of compressor with R22 is higher than R404A ??

Sincerely yours.
