Chiller had high SUPERHEAT cause of this

Күн бұрынTrying to finish the final repairs for this compressor replacement to call final startup good. You never want to just assume things are good when replacing compressor because there's almost always something that killed it. I also show the EXV calibration procedure for this York air cooled chiller. Easy test any hvac technician can do to test the condition of the EEV. I was also able to fully test the recovery ability of the NAVAC NRDC4M recovery machine with fantastic results!

One of the last times I worked on a YVAA i was able to pump 220 lbs in less than an hour by just letting the compressor do all the work. I hooked up to the liquid line and let the circuit run until it went off on low pressure. Was able to recover the entire charge (270lbs) in less than 5 hours.

NAVAC four-cylinder I tested it with R410 I placed the NAVAC unit in front of a hot Condenser 115°F plus air and a recovery cylinder in the hot air flow intentionally and it still had no problem recovering refrigerant and filled the cylinder like it didn’t even know it was in 100° + heat

Ive tried telling my guys for years, wires and hoses don't know WHAT COLOR THEY ARE! But it does help guys in the beginning.

Does it add that much cost to just replace known failure points (EEVs, sensors) while the unit is being repaired. Is it something customers will not go for because of the increased cost. It had to cost a few thousand to remove refrigerant and replace the valve.

Looks like a stepper regulator valve that failed, replaced one of those before on some older heatcraft unit.. could be wrong though.

Haven't worked on many York chillers. They seem to be problematic. Where I'm from most Trane, carrier or AAON
@HVACTIME Жыл бұрын
They have the same issues the rest of them do. Just comes down to age and stress. I have a lot of York chillers so it looks like a lot of failures on my channel.

Sure it works but is an extremely inefficient way to do it especially when dealing with large tanks.

Keep learning bro, you can be a great tech someday if you want it enough. If you're not willing to use up a good portion of your free time to learn it, then you will just remain an ok tech. Good luck
