In this chapter, we discuss the basic elements of thermoeconomics, which include cost balances, means for costing exergy transfers, and several moeconomic variables used in the evaluation and optimization of the design of thermal systems.
Before continuing with the discussion of the remaining two ther- moeconomic variables and we consider the effects of changes in the exergy destruction or exergy loss in one component on the exergy input to the overall system.
When applying this methodology, recognize that the values of all moeconomic variables depend on the component types: heat exchanger, com- pressor, turbine, pump, chemical reactor, and so forth.
ANALYSIS The accompanying table (on page 442) summarizes the ther- moeconomic variables calculated for each component of the cogeneration system using the data from Example 8.1 and the definitions from Tables 3.3 and 8.2.
