A/C System Basic Climate Control
Compressor
•
The compressor has the task of increasing the refrigerant pressure, as well as circulating
the refrigerant through the system. During this process the temperature of the refrigerant
rises. To do this it is driven by the engine via a belt. To make sure that the compressor is
not driven all the time, and that no unnecessary load is generated, there is a magnetic
clutch to decouple the compressor load from the engine (see the section ‘Control’). The
compressor is one of the two components that separate the high-pressure side of the
A/C system from the low-pressure side.

•
The compressor is mounted on the engine. To allow for the motion of the engine, the
refrigerant lines to and from the compressor are flexible.

The different types of compressors used in Mazda vehicles are explained on the
following pages.
