Hello everybody. I'm new to the forum so please be gentle!
Been in the office too long, I'm looking for help with the quickest method of recovering refrigerant from a large a/c system. This consists of 2 D/X coils with separate cond units on a roof 2 floors above. I have heard of the push-pull method, not sure what it entails, if someone could enlighten me would be most grateful. Any help appreciated. Cheers.:confused:

Push pull or liquid recovery method involves pushing the vapor and pulling the liquid. When no more liquid is present in the circuit, then recover the vapor the normal way:

Have you thought about a custom cooler that cools the recovery cylinder very cold so refrigerant quickly migrates inside? In that case, connect the recovery unit (not running) as for vapor recovery but also have a liquid hose as with liquid recovery.
When the liquid recovery by cooling the cylinder has completed, close the liquid valve and start the recovery unit, keeping the cooler running.
The bucket of ice water was patented a while ago
It doesn't work in winter time for air cooled equipment. It works quite well in Siberia. When the ambient air is -60°C, the pipes inside the air conditioners are almost vacuum and the liquid is stored in the remote condenser.
Only ever had to worry about AC not food refrigeration. They would not know the AC was dead until summer.
I thought the ozone layer absorb all the lost refrigerant :D :D :D :D :D :D :D :D

Push Pull is an effective method for recovery but modern reclaim units that can pull liquid or vapour will save you all the hassel.
