Heating function
As the comfort module is able to quickly mix the primary
air with room the air, PARASOL Zenith is ideal to manage
both cooling and heating. Heating spaces with air heated
above room temperature discharged from the ceiling is a
good alternative to conventional radiator heating solu-
tions. The benefits achieved include lower installation
costs, simpler installation and perimeter walls free from
piping and radiators.
Regardless of the type of heating system installed it is
important to consider the operative temperature in a
room. Most people are comfortable when the operative
temperature in winter is in between 20–24°C, and the
optimal comfort requirements are normally met when the
room temperature is 22°C. This means that for a room
with a cold perimeter wall, the air temperature must be
higher than 22°C to compensate for the chilling effect of
the wall. In new buildings with normal insulated perim-
eter walls and normal standards of window glazing, the
difference between the room air temperature and the
operative temperature is small. But for older buildings
with worse windows, it may be necessary to raise the air
temperature to compensate for the chilling effect. Dif-
ferent operating scenarios can be simulated easily using
the Swegon ESBO software to calculate the heat balance
where both the room air temperature and operative tem-
perature are specified.

Supplying heated air from the ceiling results in some
stratification of the air. With a maximum supply flow
temperature of 40°C, the stratification is non-existent,
while at 60°C it can be around 4 K in the occupied zone.
This only applies during the warming-up phase, when the
room is unused and there is no internal load. When the
room is being used and lighting, computers and people
are present, the stratification is reduced or disappears
depending on the heating load.
Laboratory studies, computer simulations and refer-
ence projects all show that a good indoor climate will
be achieved by means of the PARASOL Zenith comfort
module whatever the time of year.
