EVAPORATOR CONSTRUCTION/OPERATION

BUE071161810N01

• A mixture of refrigerant and oil enters the bottom of the evaporator through the evaporator inlet tube and is routed so it flows through the partitioned first four plate/fin sections.

• The next four plate/fin sections are partitioned to force the refrigerant to flow toward the other end of the evaporator.

• The next five plate/fin sections are partitioned to force the refrigerant to flow toward the bottom of the evaporator.

• Refrigerant then continues through to the remaining five plate/fin sections and then moves out of the evaporator through the evaporator outlet tube.

• This W-pass flow pattern transfers the flow of refrigerant and oil through the evaporator.
