im fairly new to refrigeration, 6 years exp with comfortcooling and heating. slowly ive been working on more and more med temp refrigeration. im having difficultly with a warehouse evaporator blowing water. there are 6 evaporators in this particular building, 2 evaporators per condensing unit. access is difficult, the evaps are 18 feet up.the system with the problem, only one of the evaporators is blowing water, i checked what seemed to be the obvious, cleaned the coils, checked the condesate drain for proper drainage. system is fully charged, 30 superheat at the compressor, 5 degrees subcooling out of the receiver. when i go back i plan on taking a hard look at the txv, superheat leaving the evaporator at issue, sublcooling at the txv, even refrigerant distribution from the txv, temp drops accross the coil. none of the other 5 evaps are doing this, the other evap on the same circuit is not "raining". im asking for any other insite on what to look for before i tackle this. thanks. would my pschometric chart explain why this is happening?
