    Carrier 30GH245

    Hello !

    I write for first time in this forum .

    I have wonder if someone can tell me the answer.

    I have a Carrier Air cooled chiller , Model 30GH245
    800 KW cooling power , with 8 reciprocating semi-hermetic compressors 06E. 2 circuits and Refrigerant R22.

    Can this chiller be using for ice rink somehow ?
    The ice rink need about -4 , -5 degrees .

    Thanks in advance !

    I believe that unit is only rated to mid to 30's in it normal configuration and I,ve never seen one used for lower than 40 degree supply.

    You need to check with your local reps for a unit designed for low temp apps.

    In addition to this chiller not being designed for this, R22 is not a low enough pressure refrgerant to use in such an application. Not to mention it will soon be a very costly commodity.

    I use to have a York system for a ice rink that used R22. It was not a glycol system. The temp was only about 20 degrees. Other glycol systems I have seen had the ice temp of about 25 degrees. Those were ammonia units.

    You would HAVE to run glycol since your below freezing!!!!!!!!!!!!!!
    The unit itself is not designed for those temps. Even if the unit has factory options for lower temps they are only down to around mid teens if I'm remembering correctly. Thats not even considering the problems you would have with oil return. There are units that operate on R22 at -15 evap temps but they are designed for those apps.
    I would say the answer to your original question is simply no!
