[Reference] Dewing test conditions
Indoor side: 27°C dry bulb temperature
24°C wet bulb temperature
Air volume: Low air volume, operation time 4 hours
Installation under high-humidity atmosphere
In some cases including the rainy season, especially inside of the ceiling may become high-humidity atmosphere
(dew-point temperature: 23°C or higher).
1. Installation to inside of the ceiling with tiles on the roof
2. Installation to inside of the ceiling with slated roof
3. Installation to a place where inside of the ceiling is used for pathway to intake the outside air
• In the above cases, additionally attach the thermal insulator (Glass wool, etc.) to all positions of the air
conditioner, which come to contact with the high-humidity atmosphere. In this case, arrange the side plate
(Service plate) so
that it is easily removed.
• Apply also a sufficient thermal
insulation to the duct and connecting
part of the duct.
