Introduc on
Capturing Heat
The Combined Heat and Power Exhibi on Project is developing a func onal micro-scale demonstra on of a combined
heat and power system in order to increase awareness and
understanding of combined heat and power technology.
Combined heat and power (CHP) technology captures and u lizes waste heat from electrical genera on processes. Harnessing waste heat can result in use of up to 80% of the
energy released, greatly improving the efficiency and sustainability of the process.
The hot water heat exchanger cools exhaust from 1200ºF exi ng the generator to the 600ºF required by the absorp on
chiller. The chiller itself requires only 65W to operate. The
hot air heat exchanger is located a er the chiller as air can
be heated easily using already cooled exhaust.
Customized prefabricated heat exchangers are very costly
and crea ng high-performance heat exchangers is challenging. In order to meet unique geometric constraints while
achieving efficient heat transfer, this system uses sec ons of
a modified radiator heat exchanger installed in custom sheet
metal housings in order to heat air and water. A radially
finned heat sink was similarly modified to fit around the absorp on chiller boiler tube (render shown at right).
System Integra on
The “waste” heat can be used to heat air or water. It can even be used to cool air or water by means of absorp on chilling. Providing hea ng and cooling with the energy from
an exhaust flow also reduces the demand for electrical energy
for such needs. Our project is developing a system that will
use the heat from a generator’s exhaust to produce interacve hea ng and cooling effects to demonstrate the u lity of
CHP technology.
Cooling with Heat: How it Works
Key Points




Thermodynamics allows cooling with heat
Harnessing waste heat from electrical genera on is viable, economical, and efficient
The CHP system is now opera ng at Messiah College and is expected to save $800,000 per year.

Partnerships
The Collaboratory is partnering with UGI Performance Soluons and Messiah College. UGI Performance Solu ons is a
leader in industrial combined heat and power installa ons
and has recently worked with Messiah College to install such a
system on campus.
