Regassing Copeland R22 Compressor

[Tophertony]

I make vapor phase systems for PC cooling but I have never made a water chiller before, which is what I am about to do. Essentially, it uses a hx to transfer heat from denatured alcohol mixture to refrigerant. Drawing is included.

Anyways, I want to use some r22 compressors I have but I want to regas them to use r404a or similar gas. I dont know what all I have to watch out for, or if the compressor can handle this type of refrigerant in a LBP setting.

Also, instead of a typical air cooled condenser, I will also be employing a water cooled condensing loop. Load will probably be about 400-600w in all.

Specifications:

• Model #JRL4-0100-PAA-900
• 1 HP
• 11,000 BtuH
• 115 VAC
• 60 hz
• Single phase
• R-22
• High Temp
• Mounting centers - 4 13/16"W X 8"L

It might just be me not being able to read your drawing.

BUT....

Are you using the water you cooled down to cool the hot gas from the compressor?

BTW, what's the black Xs there to indicate?

Regarding your question;
Yes it's possible but not simple, your best bet is to find a local friendly fridge guy to do it for you.
