Week 2 Air Conditioning & Compressors

This week we started on Air Conditioning and the cycle in which the different types of refrigerant flows from the A/C Compressor to your condenser, expansion valve, evaporator and eventually starting over at the compressor. this process is was fuels the cold air into the cabin through the air ducts from the blower and motor.

Intake of a duel pistol compressor, center circles are the discharge from small metal plates that lift up on the compression of the pistons discharge. The other holes around the 2 center protruding are the intake holes that suck in the refrigerant.

This picture instructor Mick is showing us that this clutch field coil got hot and so it melted the seal and threw oil and refrigerant around the clutch pulley and everything else in the engine bay. Does running A/C add a lot of load to your engine while idling and while normal driving?
