ABSTRACT:
A refrigerant recycling system includes a recycled refrigerant tank for storing recycled refrigerant, and first and second valves connected in series between the recycled refrigerant tank and atmosphere. In purging non-condensables from the recycled refrigerant tank to atmosphere, a programmed microcontroller holds the first valve open for exposing the pressure transducer to the pressure in the recycled refrigerant tank, and opens the second valve when the measured pressure exceeds a predetermined pressure for purging non-condensables to atmosphere, holding the second valve open until the measured pressure drops below the predetermined pressure. The pressure checking and purging steps are repeated after a short period, as often as necessary until the measured pressure is less than or equal to the predetermined pressure while the second valve is closed and then, after a longer delay, the system goes through one more pressure check and, if necessary, purging operation.
