york used to put the drier right at discharge on compressor. there are driers rated to handle this but the capacity of the drier drops.
I've had a York package unit blow the glass outta the compressor in Afghanistan bc the filter drier was on the discharge line and it was completely blocked... 165 degree odt and condenser coils dont play nice together
trane compressor had been changed out by someone who didnt know what they were doing installed liquid line filter drier 6 inches from compressor discharge also cut down the discharge from 1/2 inch into a 163s drier. I got the call for no cooling condenser fan motor had locked up compressor pumped so hard before it went out on overload that it blew the teflon seal out of the roto-lock must have blown a cup of oil out into the unit. please dont install liquid line filter driers in the hot gas discharge line.
I've had a lot of leaks on those internally installed (non-copper) filter driers inside condensers on these specific York system in this specific development that are about 6-7 years old. When i check the charge and its quite low the filter drier is the first place i check on these systems then the evap coil.
Why can't you pump down a micro channel style condenser as long as it is not more than the factory charge?
Move the filter drier inside and install approx. 6" from the txv. No rusting and better protection of metering devices.
not to hi-jack thread but where do you put the liquid line filter drier in a unit with a bi-flow metering device? from the factory i have never seen on installed.
You install a bi-flow drier...on the liquid line. When there is no factory installed drier I like to put them inside close to the air handler. They will function fine anywhere on the liq line but the paint wont fall off and rust when theyre inside.
I am referring to the type of metering device that meters in both directions, one expansion valve for cool same expansion valve for heat. its only on units that would have had a very short liquid line. Water source heat pumps and package units mostly. in this case the liquid line is only really the liquid line in one mode. where to put it?
