FRESH AIR SUPPLY VENTILATION
Operation
∗
Refer to the operation manual for details.
Features
The air supply ventilation system using only fresh air.
Any contaminated outdoor air is purified in two stages of indoor unit and outdoor unit. Fresh
air from which bacteria were removed is supplied into the room.
1. Purifying air in the outdoor unit
Thermal catalyst containing in the humidifying rotor analyzes unpleasant odor and also
removes exhaust gases (NO
X
, SO
X
).
Manganese catalyst used to treat the automotive exhaust gas is adopted for the thermal
catalyst.
2. Purifying air in the indoor unit
The air supply filter is placed at the humidifying hose outlet of the indoor unit side.
The air supply filter removes about 97% pollen and dust.
3. Controlling temperature
The fresh air passed through the air supply filter is cooled (or heated) in the indoor unit and
supplied into the room.
You can keep comfortable temperature and also replace air because the ventilation is
performed while temperature is controlled.
Pollen, exhaust gas and odor that could not be removed by the thermal catalyst and air supply
filter will be decomposed by photocatalyst.
