* A chiller capable of producing water temperatures of low 40s on the evaporator side and above 135° on the condenser side.

3
* Wherever there is a simultaneous demand for hot water and chilled water.

4
Serves app. 1 million square feet Dorms, classrooms and research labs Half a million square feet in research labs Once through air has to be de-humidified Accomplished by chilling air to 55 and reheating to maintain comfort conditions Year round heating demand

5
* 3600 tons of conventional cooling * 1300 horsepower Natural gas/fuel oil boilers

6
Two 500 hp natural gas fire tube boilers Most efficient fire tube boilers in the state 180 degree water, 190 degree stack temperature

7
Low Delta T syndrome Characterized by: Over pumping primary system Higher chilled water supply temperatures Forcing additional chillers on before chillers are fully loaded.

10
Lowest first cost option Solved Boiler condensing Reduced run time on boiler by 3 Reduced maintenance on boiler Essentially solved low Delta T syndrome

11
Allowed Us To Condition Our New Student Center From Our Existing Central Plant No Square Footage Needed for Boiler in New Building No Air-Cooled Chiller Near Building (Noise) Lowest Design/Construction Option Total Project Cost ~ $550,000 Added Cooling and Heating Redundancy ~ 400 Tons of Cooling (4,800,000 BTUH) ~ 180 Boiler Horsepower (6,000,000 BTUH) Most Economical Way For Us to Make Hot Water

COP is the ratio of the heating or cooling provided over energy consumed * Electric Boiler/Water Heater ~100% Efficient * 1 KWH = 3,412 BTUs * COP = ~1 22

23
COP is the ratio of the heating or cooling provided over energy consumed * Natural Gas Boiler Combustion Efficiencies * Fire Tube Boiler – 83 to 85% * COP =.85 23

24
* What Would The Formula To Calculate COP Look Like If We Had An Application For Using Both Hot Water (Product) and Chilled Water (Byproduct) Simultaneously ? 24
