d) Preventing the free-access floor from being collapsed because of the opening
Horizontal forces applied to the free-access floor during earthquakes or when heavy
equipment is carried in could cause the floor panel to shift, depending on the structure
of the free-access floor and the shape of the floor panel opening, leading to free-
access floor collapse. When such an opening is built, the free-access floor should be
reinforced with bolts or brackets to guard against possible collapse.
(4) Installation of a floor panel for a building air conditioner
A floor panel must be installed only for buildings air conditioned by underfloor
ventilation. When underfloor ventilation and room air conditioning are jointly used,
the floor panel is not required.
a) Underfloor ventilation
If only underfloor ventilation is used to air condition the computer room, floor
panels with an airflow control damper or airflow control panels must be installed to
allow cold air to rise up from under the free-access floor to circulate outward into
the room. This is proceeded to enable the air thus circulated may cool the heat
penetrating the computer room, and heat generated by room lighting and by the
operators' bodies.
