Condenser
Where is high temperature vapor found
At the discharge of the compressor or confenser
Why is oil added to the refrigerant
To lubricate of the compressor
Keep refrigerant migrating
Recycle and filtered refrigerant can be used where
By the same owner in the same type of equipment

The purpose of the condenser in a refrigerant system is to
Cool the refrigerant gas
Change the refrigerant vapor a liquid state
Filter out the moisture
Change the refrigerant vapor to a liquid state
