They're using a R410A condenser. the indoor metering device is what ever size piston the condenser calls for, or a R410A TXV. Voltage is what ever the building has. R410A units come in the same voltages as R22 condensers did.
Converting R22 systems to R410A
I read a articular that was posted about converting system from R22 to R410A .Where they talking about replacing the meting device in the air handler or the evaporator coil & if so, where did they find a device for 410A? Also how much changes has there been from R22 systems to the
R410A systems, 3 phase 208\230 volt ?

Thanks for the feed back. Can I purchase a metering device & make my own conversion?They're using a R410A condenser. the indoor metering device is what ever size piston the condenser calls for, or a R410A TXV.

Have you try Freon 421A, as a alternative to R22?yes. Done fairly often.
No I haven't.Have you try Freon 421A, as a alternative to R22?
What about other Freons for drop-ins for R22?
NU 22B, but still has a 5% capacity loss. So don't like it for units there were sized right. haven't tried MO99 yet, and probably won't since it too has a capacity loss.
OK thanks
Sound like, they taking about metering device (TX valve , capillary or piston ) type device, this R410 devices are specifically design to handle high pressure.
as for the converting from R22 to R410 its very expensive work , all depend on the system capacity if the system less then 10Ton it cheaper to replace complete system.
