Who know the practical way of removing air from R22 system? Now I recycle the refrigrant and recharge it. I think it's not effecient.

Hi LC,
you're right, it's un-economical to keep reclaiming and recharging refrigerant, for you and your client.
As I understand, if there's air getting into your clients sealed refrigeration system, I'd say start looking for a leak.

@clearchris: Neither can I recomend this practise, our job should be to minimalise refrigerant expelled to the ozone.

... Air can't contaminate a refrigerant, it only can remain as an incondensable on the top of it.

@Peter_1: True, air is made up of lots different parts, that may remain uncondensible and un-noticed, but the moisture carried in the air can affect the hydroscopic oils and cause problems.

Hope this helps!
