9.4 Case Studies
9.4.1 Thermally Driven Multigeneration System
This is a case study based on work done by Dincer and Zamfirescu (2012) which illustrates the benefit of multigeneration systems with an incremental number of outputs. The energy supply is heat at intermediate-temperature level, derived from waste heat recovery. Therefore, renewable energy is used. The configurations of considered systems are according to Figures 9.1–9.3.
Equations (9.1) and (9.2) are used for energy and exergy efficiencies calculation for the considered system under some reasonable assumptions, described below. Because the system uses only renewable energy it is not meaningful to analyze the specific emissions factor defined by Equation (9.3). Rather, the system will ...
