r414b in to a r22 unit will it work

[jtalo11]

I want to know what may happen if i put r414b into a new r22 condenser, we install a new deil and added r414b into it work good. so i order a new unit for a walk in ref but can't get r22 without epa les, going for it but need to get this walk-in unit runing now or lose money every day and i had a guy come look but wants about $1,000 to charge. I have 27 lb left of r414b and no r22 any help.

R 414b is normally used to retrofit an R-12 system it has a lower density then R-22 so the new compressor may loose about 30% efficiency at 20 *F evaporator and this could make the condenser too big but if you use it you need to pay attention to the following:
. TXV valve adjustment / superheat setting (use Vapor side of PT chart)
· Pressure controls (cut in / cut out)
· Pressure related switches or controls – difference from R-22 pressures
· Irregular frost formation with high glide blends
