COMPONENT FUNCTION WITHIN SYSTEM
IPDM E/R controls the magnetic clutch and ECV (electrical control valve) according to the requests from the A/C amp. and ECM, and changes the A/C compressor drive and refrigerant discharge amount.
INDIVIDUAL COMPONENT FUNCTION
For controlling the A/C compressor, a magnetic clutch
that drives the A/C compressor is used, together with an ECV
that changes the refrigerant discharge amount.
Magnetic Clutch
The magnetic clutch turns ON/OFF, transmitting the rotational motion of the engine to the A/C compressor.
ECV (Electrical Control Valve)
Changing the cam plate angle, it changes the piston stroke and controls the refrigerant discharge amount.
