Everyone
knows that saying and the majority made already painful experience with assumed
bargain.
However,
what happens in recent months with the power rating for some cooling ceiling
systems has nothing to do with honesty and physics.
The
aim of all systems should be to keep the surface temperature of the ceiling panel as evenly as possible on a minimum permissible
temperature.
But
that only works with optimized heat exchanger surface.
Here
are some tips for planners, architects and builders to facilitate the comparison
of tenders.
How
big is the direct contact area between the cooling ceiling and the ceiling panel?
+
Number of rows?
+
Profile
width? Profile length? (Contact area
= profile length x profile width)
+
Distance between the tube rows? (Division)
How
are the benefits measured, which are shown in the DIN certificate?
+
Number of rows?
+
Profile width? Profile length? (Contact
area = profile length x profile width)
+
Distance between the tube rows? (Division)
What
was offered?
+
Performance relative to the activated surface?
+ Performance
relative to the active surface?
+
Performance
relative to the ceiling area?
+
Performance
relative to the base area?
How
is the long-term contact between the chilled ceiling elements and the ceiling
surface ensured?
Emits
the element solvent?
Is a final infrared
examination provided?
It
is far from wishing to complicate the chilled ceiling technology. But with
relatively few specific comparisons, everyboby separate the wheat from the chaff.
