    Ice formed on capillary tube



    I'm wondering that ice formed on the outlet section (Just before evaporator inlet) of the capillary tube is normal. Anyone please comment on this situation.

    No, not normal on an AC system although you can sometimes get frosting.

    Other than short of gas, any others posibilities? The high side gauge is quite high as 305 psig for R404A.

    It's Chiller system. One condensing unit for two different refrigerated cabinets with different loads and temperatures.
