    Frown R22 Replacement

    What are all of you doing for a replacement for R22?

    In what way? If it is an R-22 system that needs charging I use R22. If the system needs replacing then I go to a 410 system, assuming HVAC.

    ok, did not see any thing first troul around will look again. Boss is looking into replacing some outdate equipment around campus and ask me my imput, 410A was the only replacement I could think of right off hand. Was interrested if there was any new refrigerant that may be a long term replacement. Lot of the guys I work with do not like the high pressures of 410A.

    I remember techs saying the same thing when we went from R12 to R22 for A/Cs.

    If your campus has more cash than they know what to do with, go with new 410A units.

    Worry later about tree huggers getting 410A phased out.

    If the equipment is still good.... there are replacement (NOT drop in, NEVER mix R-22 with something else). Most require recover, N2 flush, new LL drier, replace schraders, then charge with new. Some play acceptably with MO, some need POE. Most operate similar to 22, yet at 85-95% capacity.

    There are lots of threads on this recently, I think I have posted at around 5 or 6.

    Personally... Install 410 equipment. Solves lots of problems and is a better value for the customer. Higher pressures are not a big deal... just follow proper safety procedures we should be doing on 22...

    Yeah, they said the same thing when R22 came in and started replacing R12. I don't know what is available commercially but the new big refrigerant should be CO2.

    Was wondering why we don't use more ammonia systems? Seems like this would be more enviromentally freindly.

    Not trying to be smart. But a r-22 unit shouldn't have anything else used in it. If a system needs r-22 on a regular basis, its probably time to replace it with a R-410a system.

    at least when you breathe ammonia you know to get out of the area. Breathing R22 isn't any better.

    The problem with an amonia system is that breathing anhydrous ammonia will in all likelyhood, ummm put you in the hospital or kill you. Nasty stuff if you aren't carefull with it. I wouldn't want an ammonia system in a residential situation.

    407c is also used in many systems. The pressures are close to R-22. I was told by a Supply House that 410a will start being phased out in the next 5 years due to its cause of the greenhouse effect.
