Fundamentals Basic Climate Control
Getting Comfortable
•
To change the level of comfort in a building there are several possibilities: open a
window, turn on a fan, adjust the thermostat, take some clothes off, or put some clothes
on. While it’s possible to do all of these things in a vehicle, there are of course practical
limitations. When driving in the rain, opening a window becomes impractical. The driver
of the vehicle might also find it difficult to keeping taking clothes off, and putting clothes
on.

So a vehicle has a climate control system to allow the driver to create a comfortable
climate. To allow the driver to do this it has to be possible to change the two main factors
that affect our comfort: temperature and humidity. At the same time the air needs to be
cleaned, and the direction and speed of the air stream must be controllable.

The air entering the vehicle can be warmed, or the warmth can be taken from it. There is
no way to create ‘cold’. It is important to keep in mind that
heat always travels from
warm to cold . The two following examples illustrate this fact.
