Welsh Water is firmly committed to energy conservation and promoting
energy efficiency. So when ATS was tasked with designing an energy
efficient ventilation solution at the Cardiff Bay plant, the ATS
PUREFLO system was the obvious choice.
The
huge amount of heat emitted from the variable speed drives in the motor
control centre was a particular concern for the client. High
temperatures in these rooms could potentially cause the motor control
centre panel to trip-out causing loss of pumps in the works.
To
manage these high temperatures and to prevent process gases affecting
the operation of the control systems ATS installed the PUREFLO air
displacement system.
PUREFLO
terminals supply cool air at floor level. The cool air forces existing
levels of warm air to rise. These local heat sources create upward
convection currents, accelerating the movement of warm air to the roof,
where it is exhausted.
During
the winter cycle, surplus heat recovered from the motor control centre
provides frost protection to the centrifuge building. Emitted heat is
captured via canopies located above banks of control panels and
supplied to the adjacent centrifuge area via a ductwork system. In the
summer this surplus heat is discharged to the atmosphere.
PUREFLO
ventilates the low level areas where the panels and the operators are
located, thereby using less air and less energy than traditional
systems.
The diversity of
ventilation solutions installed throughout the works reflects the
complexity of atmospheric contaminants prevalent in the various stages
of wastewater treatment, and Air Technology solution's based approach.
