I agree that those before me overcharged the unit. I also agree that 70+ is above design specs for heat... but that's what I got when I was dispatched on the call.
I recovered charge from the system in the cooling mode until I had about 10 LLSH. Suction pressures and sl temps looked good, temp split was about 20.
when i went into heat, llsh was about 20. the frost line was NOT before the txv, it was at the distributor, more than 2" downstream of the txv. the 2' of tube BETWEEN the txv (where the metering should have been happening) and the distributor (where the metering obviously was happing) was 62 d. the distributor body was below 28.
cost is not an issue for the customer... this is full warrantee, cost is only an issue for Trane and/or the owner of the company. the issue is getting this puppy fixed quickly, reliably, and once and for all. those before me have already changed the indoor txv, the indoor coil, and the liquid line (justifiably, at least the ll, it is a very saline environment and it was leaking "like a sponge". )
if I need to, i will replace the OD txv, the distributor, and the check valve. I hate to do that if it is only a strainer. what I will not do is cut the system open to see if there is a strainer there if I don't have the parts I need to fix it. it is working, (albeit marginally) at this time, and I try to adhere to the hippocratic oath... first, do no harm.
so
is there, in fact, a strainer between the OD TXV and the OD distributor? or any guess why else I might be metering refrigerant not AT the TXV, but 2" downstream?
