Design data Example
■ Geometry of the room
■ Fabric heat losses
■ Room temperature
■ Extract air temperature
■ Comfort requirements (acoustic)
Geometry ..................................50 × 70 × 12 m
Fabric heat losses .....................350 kW
Room temperature ....................20 °C
Extract air temperature..............22 °C
Comfort requirements ...............Standard
Comfort requirements
Define the fan speed in accordance with the acoustic requirements:
■
Low noise level
→
Fan speed 1
■
Normal noise level
→
Fan speed 2
Standard
→
Fan speed 2
Mounting height
■ Calculate the actual mounting height (= distance between the floor and the bottom edge of
the units).
H = Hall height – distance from ceiling – unit height
■ Compare the actual mounting height with the minimum and maximum mounting height
(see Table B9 and HK-Select).
DGV-6/30 → OK
DGV-6/60 → OK
DGV-9/60 → OK
Minimum number of units
■ Determine the minimum number of units for each unit type. Take into account the following criteria:
– Floor area covered
– Heat output
– Unit clearances
