Got an old D-B unit with a junk TX. Anyone know how to read the nomenclature? What's the tonnage? I'm tempted to say 1600 btu on the condensing unit? Never seen a model number with an ampersand...

Straight A/C, thank goodness. Adequate insulation. Reg valve is cranked down pretty hard...I guess we watch and see.

5 ton air handler on 5 ton semi hermetic compressor. Haven't checked airflow, but of course, all this was designed by the building engineer. :whistle:
I agree thoroughly...48 degrees is mighty...

Can someone give me some general tips for setting water reg valves on water cooled units? Specifically, what sort of delta T are we looking for? What sort of condensing temps/pressures? My...

I've been confused about this...
We have several "in and out" water source heat pumps and straight A/C units here. water temps are generally about 53*. Prior to the creation of the 410-A water...
Not exactly sure if I'm posting this to the right forum, but does anyone know of any job opportunities in the Caribbean? Occasionally you hear of work in the Bahamas or Virgin Islands, but I don't...
He's a bit of a chewer, so I don't want him to electrocute himself. We've been known to have -50 nights, and when it's that cold, of course, he comes in. I've built him a nice house...
This is for all my cold-weather buds.
Aside from leaving your best friends inside all winter, any ideas on how to keep them warm? Right now we're trying to cohabitate with our 100 lb. husky, but he...

I guess when I said not a terribly long lineset I should have clarified...the condensing unit is probably at least 70' from the evap. I'd say about 100' of suction pipe, and all back downhill to the...

Just trying to eliminate the possibilities at this point. We did some adjustment on the crankcase pressure reg, to let more refrigerant through, and already I can tell a difference in...

3-phase copelamatic. It only trips on oil pressure when the box and coil are getting down to 0.
Just discovered that Zerol makes an AB in a lighter weight. Would it be wise to try to change to the...

I'm thinking you are probably right. I've spoken with tech support at ICOR about the pipe size, etc...and he says no prob, but I'm skeptical at this point, and they're trying to sell their product. ...

Had a freezer lose its charge and about 90% oil over the weekend. Of course, the refrigerant and/or oil were not labeled. So I cleared out the semi-herm Copeland of all the oil I could,...
