Sprinter 2500 V6-3.0L DSL Turbo VIN 45 (2007)
Evaporator Core: Description and Operation
Rear A/C Evaporator - Operation
OPERATION
Refrigerant enters the rear A/C evaporator from the rear A/C expansion valve as a low-temperature, low-pressure mixture of liquid and gas. As air flows
over the fins of the rear A/C evaporator, the humidity in the air condenses on the fins, and the heat from the air is absorbed by the refrigerant. Heat
absorption causes the refrigerant to boil and vaporize. The refrigerant becomes a low-pressure gas when it leaves the rear A/C evaporator.
NOTE: Replacement of the refrigerant line O-ring seals is required anytime a refrigerant line is disconnected. Failure to replace the rubber O-ring seals
may result in a refrigerant system leak.
The rear A/C evaporator cannot be repaired and must be replaced if leaking or damaged.
