    r417a vs r22 in chiller application



    Hi sirs
    We design a 39kw chiller per the r22 condition and then charge the r417a. We find the cooling capacity is much lower the designed. There's no data tell us what the exact difference between r417a and r22 in chiller application. Who have the related experience ? Pls help!

    regards
    LC

    Why you don't charge R407?
