Energy saving
z
All DC design•
Heat exchange efciency increased and larger air ow by adoption of new type turbo fan•
Advancement in comfort
z
Quiet operation was realized by adoption of new type turbo fan•
Improvement of air stream•
Adoption of high efficiency turbo fan
High efciency achieved by equaling the performance of the wing and air passing the heat
exchanger
Improvement of the flap
Making space between the ceiling, the air ows far wide and ceiling does not get dirty.
