7 ABSORPTION COOLING THEORY Evaporator with water as a refrigerant Refrigerant water sprays on copper tubes of chilled water system Changes state (boils) and absorbs large amounts of energy Water evaporates at 212 F at 14.7 psia Water evaporates at 40 F at psia CFC refrigerant changes state and absorbs large amounts of energy for ex. R134 evaporates at 40º at 35 psig REJECT HEAT CONDENSER EXPANSION DEVICE EVAPORATOR HEAT ENERGY GENERATOR ABSORBER PUMP 1/29/2015 CHP ASSOCIATION 7 PAGE 7 ABSORB HEAT REJECT HEAT

23 CCHP TURNS ON 2/20/2014 Hi folks, Congratulations to everyone on 2 huge milestones today: we got National Grid s sign off and passed ConEdison s witness test! The generators started up successfully, and we will be working tomorrow to dial in synchronicity on all systems. I appreciate everyone s hard work to get to this point. Please let me know if you have any questions. Thanks! J'aime Mitchell, LEED Green Associate Associate Coordinator of Construction Green Mission Specialist 56,000-square-foot structure is 60 percent more energy efficient than the building code requires. That's right: 60 percent more efficient, making it one of the most energy efficient supermarkets in the nation, Whole Foods says.( source greenbiz.com ) 1/29/2015 CHP ASSOCIATION PAGE 23
