K 2500 Truck 4WD V8-65L DSL Turbo VIN S (1998) | Heating and Air Conditioning | Evaporator Core
Evaporator Core: Description and Operation
The evaporator cools and dehumidifies the air before it enters the vehicle. High pressure liquid refrigerant flows through the orifice tube (front system)
or TXV (rear system) into the low-pressure area of the evaporator. The heat in the air passing through the evaporator core is lost to the cooler surface of
the core, thereby cooling the air. As the process of heat loss from the air to the evaporator core surface is taking place, any moisture (humidity) in the air
condenses on the outside surface of the evaporator core and is drained off as water.
