R-420A

[dnt]

Anyone used the R-420A blend as a replacement refrigerant in a R12 cap tube domestic refrigerator? Results?

[Dad]

Have not used it yet.

thanks for link luster I will call them and see if they recommend their product for domestic refrigerators. Looking at the P/T chart it will need to run about 0.5 psig low side so should work OK I think. I will post results in a few days after conversion.

Why is it that a good r-22 alternative (like that one is) hasn't appeared?

Never mind.I would not understand the answer anyway.

R407C is an excellent HFC R-22 replacement refrigerant.

That was interesting rayr.Thanks.

I hate to be critical but,a few things seemed out of place.
Do they have an ASHRAE number for that stuff,or are we to just take there word for it?How much have they sold,how many people are using it?


Will they pay me to try it out for 'um?

It is flammable,but it smells nice...what's not to like?

this stuff not legal to use, it's flammable
check epa gov site for list of those fined for
using halocarbon rtefrig

dnt,
The company I work with has been using this refrigerant now for over a year and a half exclusively for R-12 and R-409 and any other temp. Have found it to have a lower head pressure than the others (other then 12). And out here it is very important.
Have even (when pushed) toped off other gases till we can recover and change it out completely (to R-420).
Charge to 85-90% of name plate. On the really small units (6-10 oz) use the full charge. ( It is hard to not charge in the full weight).

Have been very happy with this gas.
Yuma,

Yep stuff is good, excellent cooling with slightly lower head and suction pressure I am a bit concerned with the compressor temp it was running about 130 to 140f on compressor shell at 90 ambient with R12 and the same with the R420A it is still pulling 2.9 amps same as with R12 but it is a old unit maybe that is just the way the hermetics were made 25 years ago? Anyway I appreciate the comments I will let her run a while and see how it does I have the supco data logger in the freezer compartment now set up for a one week test.

I would not use it in a stationary system,but auto ac would be safer. A leak under the hood would be blown away by the radiator fan.

[fonephat]

A product called Energy Release can be used in automotive systems and stationary systems also. will improve compressor perfomance.

I've been using r420 in cars and domestic refers for about 3-4 years now. Very close to r-12, works great.
