Checking the ancillary conditions
■ Maximum floor area reached
Calculate the floor area reached per unit using the
selected number of units. If it exceeds the maximum
value listed in Table E4, increase the number of units.
■ Compliance with minimum and maximum distances
Check the resulting distances based on the space
requirements and arrangement of the units, using the
information in Table E8.
Floor area per unit = 72 · 50 / 10 = 360 m²
Max. floor area reached = 661 m²
→ OK
Minimum and maximum distances can be complied with
when units are arranged symmetrically.
→ OK
Definitive number of units
With a larger number of units, there is more flexibility of
operation. However, the costs are also higher. For an
optimal solution, compare both the costs and ventilation
quality of the system.
Select 10 TWC-9s with coil type C. They ensure cost-effec-
tive and energy-saving operation.
