Purpose
The evaporator cools the passing air.
Function
The evaporator vaporizes the atomized refrigerant flowing internally, and the air passing through the evaporator is cooled by the release of latent heat. The moisture in the air is condensed at this time and dehumidified air is blown into the cabin.
Construction
The evaporator consists of the tube which passes refrigerant, and the heat radiation fin.
The cooling medium flow pattern shown in the figure has been adopted for the evaporator.
Operation
The atomized refrigerant sent from the expansion valve is captured by heat from the outside. As a result, the evaporator is cooled.
The air blown by the blower motor is cooled by heat exchange when it passes the heat radiation fin of the heater core.
Fail-safe
Function not equipped.
Interior Care
WARNING
Do not spray water in the cabin:
Splashing water on electrical parts such as the audio unit and switches is dangerous
as it could cause a malfunction or a fire.
