Copeland Scroll 7.5hp, 3 Phase Compressor, med temp
55 gal reservoir made from blue water barrel, uninsulated as of yet
Bell & Gossett BP422 Heat Exchanger
3/4hp pump
we cant get the glycol below 37ish. and its not even "glycol" yet, still 100% water.
compressor is rated 58k btu at 20F. right now there's 1" lines running from HX to reservoir, uninsulated as of yet, but only about a 25' run. cant imagine we're losing THAT much heat to ambient. ran unit for about 20-30 minutes, went from 70 ambient down to 40s pretty quickly, then stalled around 37-38.
the ac tech says he thinks the compressor is bad, but im worried he's taking the easy way out by advising we get a new compressor. its a little difficult to get into a super technical discussion with him (granma didnt teach me HVAC spanish), but he went from initially not knowing why it wouldnt get cold enough to now saying that the compressor doesnt sound right and its probly going bad.
its entirely possible that this is the case, but before we shell out for new compressor im hoping to see if there's any thing we can do to double check.
electrician insists its wired correctly and is fully powered. (dont recall if its 208 or 230)
gas is fully charged
compressor does not seem to be leaking gas
no refrigerant leaking from HX into water that we can tell (it would be oily right?)
all the pumps and condensor fans seem to be working fine
37F is pretty cold vs 70F ambient, so its obviously working- but only partially. which is why i just wanna be sure we're not missing something small or silly before we get a new unit. should we try and throttle down the recirc pump? would the uninsulated recirc lines really lose that much heat? drain/change refrigerant gas?
any advice greatly appreciated.
