Commissioning of CHP Systems - White Paper, April 2008

This 2008 white paper explores commissioning practices of Combined Heat and Power (CHP) systems applied within the built environment. CHP systems are more complex involving increased attention to atmospheric emissions and electric grid interconnection and sophisticated control logic. This paper details four example case studies. A San Francisco hotel was retrofitted with a “packaged” microturbine generator/double-effect chiller plant; a Los Angeles casino was retrofitted with an advanced reciprocating engine, hot water heat recovery, and a single-effect absorption chiller; a Brooklyn laundry was retrofitted with two reciprocating engine generators and a hot water recovery system; and a state-of-the-art hospital in Austin, Texas, was retrofitted with a combustion turbine, heat recovery steam generator, absorption and electric chillers, and thermal storage.
