GF83.50-P-3002SX Rear Air Conditioning Evaporator, Component Description
- with CODE (582) Rear air conditioner
Component Identification
Location
The evaporator is located in the rear AC housing.
Task
The evaporator is used to cool and dehumidify the interior compartment air.
Design
Disk evaporator made from soldered semicircular disks with corrugated ribs.
Function
The refrigerant, which is under high pressure, is fed into the evaporator.
The refrigerant evaporates, thereby absorbing the quantity of heat required for evaporation from the air flowing past the evaporator. The soldered
semicircular disks with corrugated ribs provide a large evaporation surface and guarantee rapid heat exchange. The humidity which condenses during the
air cooling process is diverted by way of condensed water drainage hoses into the open. The refrigerant supply is controlled by the rear AC refrigerant
shutoff valve (Y67) which is actuated by the AAC [KLA] control unit (N22/1).
