R-22 substitues for our older Systems

[risctaker]

Has anyone successfully refilled their R22 AC Systems with either R-417a or R422d? Both are listed as direct R22 replacements with the only caveat being a slight reduction on cooling performance. Given the inaccessibility of R22, both of these substitutes appear to be readily available with R422d being offered on eBay at approx. $10/lb. Would sure help forestall the expensive upgrade of the entire boat.

OK Problem solved. After MUCH research and speaking with marine AC experts, R422D will work in our original R22 systems with no modifications needed. Just follow the guidelines that call for a complete evacuation of the R22 and (if needed) a new drier then fill to approx 85-90%% of the R22 capacity and we're good to go.

Thanks for the info.

A friend told me that he was paid over $400/lb for R22 that was reclaimed from systems in one of his commercial buildings. I had no idea it was going for that kind of money.

At that rate maybe you could sell the R22 in the current system and get enough to pay for a whole new system.

$1400 for a 30 lb can.

Scary

Where you both live? It's going for 500-700 for 30lb on ebay. www.ebay.com/itm/30-lb-Sealed-R22-/322563033247

Just use propane. Yes I'm serious. Some say it even works better. I may try it on my old ice machine that needs a new TXV.

The new blends have propanols and methane gasses that do not burn. Is there a way to make propane safe for that? Probably not.

Would I use propane on a customers system? No.

Would I use it on my crap....sure!

Instead of buying rum in the Bahamas.... my last two 30lb cans were $115 a pop.

Be carful using propane. Apart from obvious risk it is against federal law to use in a residential system. Of course being a boat it becomes a grey area as regards residential. Ray
