5.10 Cooling system and exhaust air
ACS
Relaxing gently while tanning. ACS controls the intensity of the
exhaust air – depending on the temperature. Sensor systems
in the apparatus measure the exhaust air temperature and set
the revolutions of the fan accordingly. That means that with low
temperatures the fan speed is low as well.
ACS also controls the body ventilator, i.e. the fan speed is
slowly increased at the beginning of the tanning session. As
soon as the customer increases or decreases the fan speed by
hand, this automatism is switched off.
Principle of the
cooling system
The following pictures illustrate the cooling system of the
sunbed.
Ambient air (if there is no air-conditioning) or cooled air mixed
with ambient air (if there is air-conditioning) (Illustr. 5-22 and
Illustr. 5-23) is blown by the body ventilator through ten nozzles
into the tanning room of the sunbed (blue).
Through the upper filter, the fan draws in air to cool the tubes
and burners in the upper part; through the front filter cooling air
is drawn in for the lower part (tubes). The exhaust air is then
blown off through the exhaust flue (green).
