Ventilation with natural cooling saves energy costs May 1st 2007 Evaporative air-cooling systems,
such as Breezair from Seeley
International, have wall-mounted
climate control panels with control
modes. In auto mode they monitor
the temperature and personal
comfort setting, automatically
increasing or decreasing the fan
speed to maintain comfort. The fan
speed can be varied manually in
manual mode and the system can
be programmed in timer mode to
be switched on and off within a 24
hour period.
The cool/vent mode gives the
choice of operating the system as
a cooler or ventilator as required.
Within industrial environments
this means that winter ventilation
can still be used to remove
vapours, odours and/or heat.
The very nature of evaporative
cooling lends itself to
environmentally friendly, energy
efficient operation.
Unlike a refrigeration system or
heat pump, energy consumption is
very low, because the cooling
effect is the result of sensible heat
being transferred to latent heat
through the evaporation of water.
Evaporative cooling energy
consumption is primarily for
operation of the fan. Evaporatively
cooling a typical building is
claimed to require approximately a
quarter of the energy consumed by
an equivalent refrigeration system,
and without the use of ozone
depleting chemicals. More articles from Seeley International Ltd: |
