(2) Ventilation
G
For general offices, a ceiling embedded-type Lossnay will be installed in the ceiling. The inside of the ceiling will be
used as a return chamber for exhaust, and the air from the Lossnay will be supplied to the air-conditioning return duct
and mixed with the air in the air conditioning passage. (Exhaust air is taken in from the entire area, and supply air is
introduced into the air conditioner to increase the ventilation effectiveness for large rooms.)
G
For board rooms, conference rooms and salons, a ceiling embedded-type Lossnay will be installed in the ceiling. The
stale air will be duct exhausted from the discharge grille installed in the centre of the ceiling. The supply air will be
discharged into the ceiling, where after mixing with the return air from the air conditioner it is supplied to the air
conditioner.
G
The air in the toilet, kitchenette, and lift hall, etc., will be exhausted with a straight centrifugal fan in each room. The OA
supply for this section will use the air supplied from the Lossnay. (The OA volume will be obtained by setting the
Lossnay supply fan in the general office to the extra-high notch.)
Installation state of air conditioning system for board rooms,
conference rooms, salons - the air supplied from the Lossnay is blown
into the ceiling, and the stale air is removed from the discharge grille.
