Efficient Outdoor Air Introduction with Heat Exchanger and Cooling/Heating Operation
Indoor unit with outdoor air treatment
The temperature can be brought close to room temperature with minimal cooling capacity
through the use of outdoor air
2. DESIGN FLEXIBILITY
High Static Pressure
Modifications to the fan, including the use of multiple arc blades, a thinner scroll and optimized
fan scroll angle, help to boost efficiency.
Dramatically higher static pressure is achieved due to improved fan performance. This reduces
limitations on unit location and allows more flexibility in duct design.

Higher static pressure and reduced noise
The use of multiple, overlapping arc shaped fan
blades makes it possible to optimize the chord
lenght and blade outlet angle. This results in
higher static pressure and quieter operation
over the entire operating range.
Rotating currents for reduced loss
The use of a thinner scroll allows rectification of
rotating currents within the scroll.
Higher static pressure
The fan diameter has been
increased and blade width
optimized, resulting in higher
static pressure.
Higher static pressure and reduced pressure loss
In addition to increasing the scroll
wrap angle and boosting the static
pressure, the outflow angle has been
optimized to reduce pressure loss in
the outflow area.

Indoor Unit Connectability
The indoor unit is connectable up to 130% of outdoor unit capacity
