Why Right Now is the Time to Install CHP

Why y CHP CHP N Now • Great Spark Spreads • Reduced Facility Operating Costs • State and Federal Incentives • Resiliency • “Green” - Reduce Carbon Footprint

Overvie Ov iew Fleet Map Company Overview Co-Energy America is a leading developer of combined heat and power (CHP) systems, specializing in the design-build and maintenance of 35 kW, 60 kW, 80 kW, 150 kW and 250 kW units. Systems can be configured up to 1MW+. Since 1998 we have designed and installed over 95 CHP units at schools, hotels, apartment buildings, assisted living facilities and other commercial properties totaling nearly 14 MW of continuous power throughout New England. Continuing to serve every customer since 1998

Absor orption on C Chill ller The refrigerant is water; the working medium that experiences a phase change that causes the cooling effect. The second fluid that drives the process is a salt, generally lithium bromide. Heat is used to separate the two fluids; when they are brought back together in a near vacuum environment the water experiences a phase change to remix with the salt at a very low temperature. At normal atmospheric pressure, water vaporizes cold enough to produce ~42°F chilled water. Hot Water Cold Water In Out 185°F 42°F

Desiccan ant D Dehumid idification ion Desiccant wheel is filled with hygroscopic gel that is used to remove moisture from the air. As moist air enters the desiccant wheel this gel absorbs the moister from the air. Cool, dry air is returned to the space. Hot water from CHP is used to heat the desiccant wheel which in turn releases the moisture. Warm, moist air is vented away from building. Hot Water In 185°F
