Evaporator Core: Description and Operation
Evaporator
The evaporator is located in the climate unit. It consists of a heat exchanger (cabin air/refrigerant), through which the refrigerant flows in a pipe system
with cooling fins.
The incoming refrigerant expands and boils (evaporates) in the evaporator pipe system and absorbs heat from the pipes and cooling fins. The cooling fins
are heated in turn by the incoming/recirculated cabin air. The incoming cabin air is then cooled to approx. 5-10 °C and can cool the cabin to the desired
temperature.
When the heat is absorbed, condensation forms on the evaporator pipes and cooling fins. This condensation is drained away through two drain hoses
under the car. Rather large amounts of water can collect under a stationary car in certain climate conditions.
