Man y’all guy rock!! It’s good you all do this even for refreshers that people have forgotten about it over the years!! Thank y’all!! I’ll be listening to the pod casts.. never listen to pod cast but y’all guys make it interesting!!!
This is a great tool for both experienced and from my perspective, somewhat new people. But I do have a question, anyone know the title of the jazz at the beginning? Thanks
one of the guys I work with had an AC unit with a weird symptoms. This is about a 4 ton American Standard 460 VAC AC PKG RTU. R22, 12 years old. Not cooling the space. Suction line is warm, like 84F, ambient is 90F, room temp is 75F, pressures are about 92/280PSIG. Superheat is very high sub cooling is in the over 20, LLT is about 82 -ish. He said the return air temp is about 80.... He recovered the charge and weighed it in. The compressor amp draw is 3.8a with an RLA of 5.9. Im thinking the compressor is weak with that amp draw and such a warm suction line. He tried to slow down the blower (belt driver ) It didn't seem to make much difference he said. Any ideas that stand out to you? Oh, its a scroll... it seems to me to be starved and that high back pressure and not that high of a load. Unless he gave me inaccurate data. Mike
