    Dry Rooms



    Hi everyone. This is my first post and new to this forum.
    I have a dry curing room I was servicing and the room won't come down to temperature.
    The room is 21 cubic meters and 3 - 5 deg. Set point
    The data on evap coil is 1.548 Frig/h 1,8 kw @ -12.5/+45 deg c (6139 Btu)
    2.236 Frig/h 2,6 kw @ -5/+40 deg c (8867 Btu)
    Suction pipe is 1/2" and liquid line is 3/8" and about 45' long going back to a rack system
    Tx valve - danfoss TES 5 with 0.5 orfice (I believe that is 3 ton) R404a
    The room can not hold temp and superheated is high with tx valve wide open. I believe suction line is undersized but will this cause this problem and what else can it be.
    Any help will be appreciated. Thank you

    Problem with liquid feed, suction line seems OK.

    What are your operating pressures? Superheat and subcooling temperatures?
