Selection of coil type
From Table B6, select the required coil type based on the
output necessary to cover the fabric heat losses per unit.
Select coil type B with 55 kW heat output to cover the fabric
heat losses at LPHW 80/60 °C and fresh air temperature
-5 °C.
Checking the ancillary conditions
■ Maximum mounting height
Select a different coil type or unit size if the actual
mounting height (= distance between the floor and
the bottom edge of the unit) is greater than maximum
mounting height H
max
(see Table B6).
■ 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 B4, increase the number of units.
■ Compliance with minimum and maximum distances
Check the resulting distances based on the hall geometry
and arrangement of the units, using the information in
Table B7.
Actual mounting height = 7.2 m
Max. mounting height H
max
= 12.5 m
→ OK
Floor area per unit = 52 · 45 / 4 = 585 m²
Max. floor area reached = 797 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 4 LHW-9s with heating coil type B. They ensure
cost-effective and energy-saving operation.
