The cooling tower is used in the HVAC system to
reduce the water temperature after heat exchange
takes place in the chiller component. The water is
supplied to the cooling tower at around 35°C, it
travels down through the ventilated core of the
tower and cooled to around 28°C. whilst the temp
drop is not high it is sufficient in transferring heat
out of the cycle. Maintenance, monitoring and
cleaning of the cooling towers is vital in ensuring
quality running conditions. [refer previous pages]

PLANT ROOM + BOILER
The plant zone contains boilers
and other plant units including
exhaust fans, kitchen equipment etc.
The boilers are responsible for heating
water to a high temperature to be used
for various functions around the building.
The HVAC system primarily uses the
HHW [boiler water] in the AHU to heat
supply air, however other applications
include supply heat for the hot water
services etc.

PUMP ROOM
The size of the Exhibition centre
means that there is a large distance
between the chillers and the AHU’s.
The pump room is therefore a vital
element in insuring the heat/chilled
water supply to the AHU.
The flow and return pipe circuit run
via the pipe riser in the Clarendon
zone behind lift one to the top floor.
They also travel the length of the
exhibition area in the basement
service area.

PUMP SWITCHBOARD
*note. The pump room occupies a large area. Firstly due to the number
of pumps and secondly to allow circulation room and areas for
maintenance and access to the pumps and surrounding service rooms.
