The heating system is a high-performance and
low-
noise full-air-mix system that provides a two-layer
stratified airflow. It features an independent
face-lev-
el
air flow and cool air by-passing functions.
The air conditioning system is essentially the same
as the conventional ones, but they incorporate a
new CFC-free refrigerant
(R134a)
system that uses
hydro fluorocarbon (HFC) containing hydrogen
atoms as the refrigerant gas to meet the CFC control
regulations that call for protection of the ozone layer.

Cool air by-passing function capable of sending fresh air
to the face even with the heater unit in operation.
3.
Independent face-level air flow function capable of sending
air constantly from the side ventilators.
4. Scroll type variable delivery air compressor that offers
improved cooling performance and quietness. <Turbo>
