Printer-Friendly ModeSVSU unveils aqua-thermal system
October 5, 2009 —
SVSU is installing Michigan’s largest aqua-thermal heating and cooling system for a new, under-construction campus facility that uses 37 percent less energy each year than a traditional boiler-chiller system.
The 20+ miles of coil
In the summer, the system will remove heat from the building and release it into the 2.2 million gallon pond; in the winter, the process is reversed. The system will supply all the heating and cooling of the new Heath and Human Services building (scheduled to open Aug. 2010), and can supply the Regional Education Center in moderate weather.
The Underground Concrete Vault
This vault houses 28 separate 2” piping manifolds, which distribute supply and return pipes to each of the 28 grids in the pond. The manifolds are arranged to balance flow to each grid and will allow flushing and cleaning of each grid individually without shutting down the entire system.
