Compressor systems, case information, piping setup, controls setup
just a few sites:
Lot's of good info here. http://hvac-talk.com/vbb/forumdisplay.php?f=56
With the EPA taking on almost gestapo-like power, the technology will be changing. Also, the newer controllers are getting VERY slick. It won't be too much longer before the store mgr will have an iPhone App that alerts him to "Failed Defrost, No Amp Draw, System 1C Ice Cream, Case 3". Think I'm kidding? This is what will make JPs concern about cheaper technicians a reality. So the question now is how do we stay relevant? These changes are coming, and coming quickly.
We need to pray for the over engineering engineers to do their job, and this will keep us all on our toes(job security). Staying up with the latest technologies and becoming heavily involved with the field R&D we might be able to help drive the way our future turns out.
The info I have been getting on the latest CO2 systems is disturbing at best, so called racks that are contained in a 6x6x6 box doesnt leave a lot of room for break downs or repairs. Sounds like maybe controls are going to be where the expertise is needed. Oh yea and pex pipe to cases with a stat and solenoid. (plumbers). Anybody else hear of these?????????
Is the C02 in the pex? Ya pretty soon well see blinking lights for error codes and any guy can find the problem. Finding good help now a days is hard.
I know of at least 4 supermarkets this summer that will be getting the CO2 systems Im referring to. And I was wrong its 4x4x4. CO2 in pex to cases, dont have alot of details but as I get more info ill share. No defrost and No humidity controls!!!!!!!
Isn't PEX plastic?
I'm foreseeing pipe bomb like explosions with shards of plastic once the primary refrigerant circuit goes down.
