BLOWER ASSEMBLY AND HEATER UNIT
The blower assembly and heater unit increases air
volume, reduces noise and improves air-conditioning
performance and the car interior air environment.
•
Installation of two-way blow full air mix heater
•
Incorporation of heater and cleaning unit
•
Increase in the outside air intake duct area size of
the blower assembly and optimization of the
shape
.
TWO-WAY BLOW FULL AIR MIX HEATER
In the heater unit, there are two currents of air, one which
passes through the heater core, and one which does not pass
through the core. One air mix door is used for temperature con-
trol. The two-way blow full mix heater with low ventilation resis-
tance has increased air volume and has reduced noise.
CONDENSER
The heat exchange efficiency has been improved with a sub-
cooling type condenser added with a sub-cooled section. The
reduction of line unions by incorporating the condenser and
receiver reduces a possibility of gas leakage and increases
service performance.
