The Compressor used is piston type compressor.
This compressor has two identical scrolls arranged
at 180º around a offset center; one of them is fixed
(fixed scroll) and the other (orbit scroll) is turned at a
constant attitude, so that the space made between
the scrolls symmetrically around the rotating shaft
moves from outside toward the center while reducing
its volume; this is the principle of compression.
The moving scroll rolls and slides in small circular
movement with a small friction loss, ensuring smooth
operation even during start-up.
COMPRESSOR RELAY
Compressor relay is located in the MDU (
Main
distribution Unit)
located in the engine compartment
which is used to operate the compressor magnetic
clutch. The magnetic clutch continues to operate as
long as air conditioner is under operation. Once the
air conditioner is put in OFF condition, the
compressor relay gets cut off and the magnetic
clutch gets disengaged from the compressor. The
cut-in and cut-off of relay is governed by the
ENGINE ECU.
