Operation (Continued)
1. Reduces cooling load
3. Office equipment room cooling
If the air outside is cooler than the air inside the building during
the cooling season (such as early morning or at night), “By-pass”
ventilation will draw in the cooler outside air and reduce the cool-
ing load on the system.
During cold season, outdoor air can be drawn in and used as is
to cool rooms where the temperature has risen due to the use of
office equipment.
(Only when interlocked with City Multi and Mr. Slim indoor unit)
2. Night purge
“By-pass” ventilation can be used to release hot air from inside
the building that has accumulated in buildings a business district
during the hot summer season.
