hi folks, quick question here regarding my walk-in cooler...
I've been battling my new walk-in cooler for almost a year, having all kinds of problems maintaining temps, compressor coming on and off too much, and the evaporator icing up like crazy (air defrost system).
I'm in western panama, so getting good tech help is tough. I finally got a hold of a guy with actual training in hvac and engineering and he's saying the root problem is they sold me a compressor that's way too big, not only for the walk-in, but for the evaporator inside said walk-in.
stats: compressor is approx 22,000 btu's
evaporator is approx 13,000 btu's
walk-in is just a 9x9x9 foot cube, insulated except for floor (tile), under roof, ambient temp 65F (high up in the mountains), not opening
the door often at all, therefore not a big load requirement
i'm told that you can have a larger capacity evaporator than compressor and it's not such a big deal.
however, you can't have a smaller evaporator than compressor (which is what i have). i suppose the metaphor would be sticking a high horse power engine in a car without dealing with the transmission. the transmission then blows up one day.
before i go raise hell at the refrigeration store, i'd like to confirm this diagnosis. any input is much appreciated. thanks!
