Evaporator Core: Description and Operation

GF83.40-P-2189RI Evaporator, Component Description

Component Identification:

Location
The evaporator is located in the air conditioning housing underneath the dashboard.

Task
The evaporator is used to cool and dehumidify the interior air.

Design
The evaporator consists of soldered semicircular disks with corrugated ribs.

Function
The liquid refrigerant under high pressure is injected into the evaporator through the expansion valve.
The refrigerant evaporates, thereby absorbing heat and moisture from the air blowing by the evaporator.
The soldered semicircular disks with corrugated ribs provide a large evaporation surface and ensure rapid heat exchange.
The humidity which condenses during the air cooling process is diverted by way of condensed water drainage hoses into the open.
