Project Scope
Stellar Energy designed, fabricated and installed two modular
chiller plants for Zayed University's district cooling system,
which provides air conditioning for all of the University's
buildings. By prepackaging the chiller plants in a fabrication
facility - instead of building it on site - the construction
timetable was shortened considerably. In addition to providing
engineering, procurement and construction services, Stellar Energy
is also supplying operations & maintenance (O&M)
services.
Stellar Energy installed all piping inside and outside of the
chiller module within the district cooling plant, connecting the
piping to the client's termination point at the entrance of the
plant. Stellar Energy also installed all the cabling from the
switchgears to the internal loads.
The system features a parallel chiller arrangement. The pumping
arrangement is primary secondary, with Stellar Energy's chiller
module serving as the primary system, and two service buildings
housing secondary chilled water pumps. The primary pumps are
constant speed, whereas the condenser pumps are variable speed.
