2 questions?


1.C-H.C. use what lubricant?


2. The discharge on my compressor is 3/16 can i use a 1/4 condenser?


thanks mohit

[the_new_guy]

one more thing,

Is it better to put low side access on service port or with a t on the suction line?

[the_new_guy]

ok i found the oil out,

the compressor is using ''compressor oil (vegetable)''.

is it the same as mineral oil?

To use 404a will i have to change oil(if its not the same as mineral)?

Will it work with 402a(if not with 404a)?

thanks

I use POE oil for mine.

[the_new_guy]

i was supposed to get a compressor with poe but there was some misunderstanding and i got this compressor.

[the_new_guy]

ok got most of the answers

i just need to know with which gases will vegetable compressor oil work? r404a?r402a? r290?

Vegitible oil will turn to gum and KILL your compressor VERY fast!!<<<

R-290 is compatible with nearly All refridgerant OIls (Minerol, POE, PAG)
Now I'm not shure but been told R-22 Will work with Minerol Oil, but I'd get a second opinion on that befor trying it

R-134a goes with POE oil

45/55% Mass weight R-290 & R-134a will work in a Minerol oil compressor fairly well and give fairly good temps.

A 80/20% Mass weitght mix of R-134a & R-600a Will out perform R-12 and run within range of Minerol oil for a small system due to the gass volocities alone will insure good oil return!

[the_new_guy]

how about a r404a r290 blend to work with mineral?

[Xeon th MG Pony]

beter off just using pur R-290 by the looks of it, you'll need at least 20% and at that point it will out perform the 404a mix as it would be so diluted if I'm reading my tables right...

Ya, you'd be beter off to use R-290 then bother with a mix, but if you're dead set on 404a NO you'll need POE oil. I don't believe you'll gain any thing by mixing them, perhaps even lose performance.

Again, Check with other more experianced members to be shure.

cool thanks
