Trigeneration Systems: A Review

Abstract

Trigeneration is combined generation of electricity, heat and cooling energy is being possible because of the commercial availability of absorption chillers. The components of trigeneration systems are prime movers i.e. diesel generator or natural gas engine, waste heat recovery boiler and vapour absorption system. Sizing of trigeneration systems is about selecting the trigeneration configuration and its system components and arriving at their capacities. Many studies were analysis studies and they do not size the system components. They restrict themselves to one or other kind of analysis thereby limiting their applicability. The first law analysis and economic analysis of trigeneration systems are the basic tools, evolved methods like exergy analysis and thermoeconomics analysis are being more rigorously applied. Some studies gives Environmental concerns like emissions. This paper reviews recent literature about trigeneration systems in which physical trigeneration systems are analysed and reports the analysis tools employed.
