MODELLING AND ANALYSIS OF BUILDING SYSTEMS THAT INTEGRATE COGENERATION AND DISTRICT HEATING AND COOLING

Marc A. Rosen, Wey H. Leong, Minh N. Le

Abstract: The modelling and analysis of building systems that integrate cogeneration and district heating and cooling are described. The analysis work uses exergy methods, in addition to the more conventional energy analysis, to evaluate overall and component efficiencies and to identify and assess thermodynamic losses. Exergy analysis is a relatively new analysis technique that provides enhanced understanding of the characteristics of energy systems and can assist design and improvement efforts. The modelling efforts focus on simplified models that can be assessed relatively straightforwardly and facilitate the application of simulation tools. The use of thermal energy storage and the impact of heat losses in the ground are considered. The latter can be significant for the system components that can be on-or below-ground, including the buildings, any present thermal storage and the district heating and/or cooling piping. The results should assist in the enhancement of simulation techniques for building energy systems.
