We are hooking up a unit that was relocated. In the piping they have a
refrigerant heat exchanger from liquid to suction.
Air cooled Copeland, inside unit outside they want us to convert.
I stated that they have to put a fan on the compressor, put a suction line
accumulator on it, crankcase heater and fan cycling since it gets zero up
here in Ohio. BTW, its 404A
Question is, Didn't Jim Lavell (Spelling) once say he didn't like heat
exchangers on the new refrigerants? Should I take it out?
What's the rules for heat exchangers?
I think Jim may have stated that it could be a problem with those with
glides but I can't remember. Heck, I'm not sure if it was Jim that mentioned
it either, but I know I heard it.
