1.2 OPERATION OF THE UNIT
Evaporative cooling is a completely natural way of producing refreshing cool air that have
been specifically designed for the cooling of industrial and commercial building.
It is designed for outdoor installation with down, top and side discharge and also as
internal suspended cooler.
Cooling is provide by Evaporative heat exchange which take advantage of the principles of
the latent heat of evaporation where tremendous heat is exchanged when water
evaporates. It makes use of the free latent energy in the atmosphere.
Water is brought into the cooler from the mains water supplì and is pumped up to the top
of the unit using circulation pump. The water is then dispersed over the Celdek pads using
a water distribution system which allows the water to flow continually over the pad.
The pads become satured, air is drawn through the pads and the water evaporate causing
the air to cool. The cool air is then ducted round the building to provide cooling by means
of an axial fan.
The control system comprises of a main control panel which controls all components by
communicating with a wall mounted control box and a set of external inputs (like
thermostat, humidistat, timer, alarm, etc)
1.3 CONSTRUCTIVE CHARACTERISTICS
Evaporative Cooler AD 14 is supplied with:
-
The cooling pads
are cellulosa based 680x850x100 mm thickness
-
Axial fan 1 to 5 speeds
and high static pressure
-
Control board with microprocessor
is the heart of control system and
connected to a unique level probe system empties completely the sump whenever
the system goes out of cooling mode, so that no stagnant water remains in the
system and when the water approaches the scale index. It is supplied with 30m
cable
-
Circulation pump
is pumping the water
from the sump over the pads via a water
distribution
system. 50W, 30 l/min
-
4 water level probes
to check water level into the sump. They also check
through electronic board the quantity and quality of the water.
-
Water supply valve and drain valve
controlled by electronic board
-
Wall mounted control box
could
be connected to thermostat to give automatic
control. Facility to connect to timer, humidistat and fire alarm contact.
-
Water sump and side panels
are injection moulded structural from
polypropylene. The cabinet is UV stabilized and corrosion free.
