High School using Joint ORNL/SEMCO Developed Integrated CHP System
Submitted
by: Jim Sand, Cooling, Heating and Power
ORNL’s Jim
Sand has teamed with SEMCO Inc.’s John Fischer, of Columbia,
Missouri, C&M Engineering, and Southern Engineering in an R&D effort
that will integrate a 200 kW reciprocating engine generator with 4 integrated
active desiccant rooftop systems processing 24,000 cfm of ventilation air
for a school in Floyd County, Georgia. Heat recovered from the natural gas
IC generator set will be used for desiccant wheel regeneration during the
cooling/dehumidification season and for space heating in cooler winter months.
These SEMCO units are the source of cooling, dehumidification, fresh air
ventilation, and heat for the school classrooms they serve, so they will
be on 100% of the occupied hours and quite possibly employed in a re-circulation
mode during unoccupied periods. This R&D work will demonstrate what
should prove to be a very cost effective, energy efficient approach to integrating
three important technologies: natural gas power generation, hybrid active
desiccant air conditioning, and exhaust air total energy recovery. The hybrid,
active desiccant HVAC product being driven with electrical and thermal energy
from the DG source is a packaged rooftop product resulting from earlier
DOE/ORNL product development R&D (ORNL/Sub-01-4000010402). The
Administration of Floyd county schools has issued a December 8, 2004,
News Release describing the innovative features of this new HVAC approach
in the school’s design (see
attached file).
