The reason for the compressor pressure ratio effect is that an increase in this parameter increases the outlet temperature and decreases the mass flow rate injected to the combustion chamber. As the first term in the total cost rate (equation 6.2) is directly associated with the mass flow rate of the fuel, any decrease in this term results in a decrease in the objective function. This is why the scattered distribution for the compressor pressure ratio achieves a maximum value within its range. Figs. 6.40a and 6. 40b show the effect of HRSG low and high pressures on both objective functions. An increase in these design parameters is seen to have a positive effect on system exergy efficiency and a negative effect on total cost rate of the system. An increase in HRSG high pressure results in an increase in the steam turbine work and increase in HRSG low pressure, and leads to an increase in absorption chiller cooling load. According to equation (6.1), increases in both ̇ and ̇ result in an increase in system exergy efficiency. However, an increase in HRSG pressures results in an increase in HRSG purchase and maintenance cost, which leads to an increase in last term of equation (6.2). Since, an increase in HRSG pressures has positive and negative effects on the objective functions, they have scattered distributions within their allowable ranges. Fig. 6.40c and 6.40d show the effect of HRSG pinch point temperatures on both objective functions. It is seen that an increase in pinch point temperature results in a decrease in system exergy efficiency. This is due to the fact that the higher the pinch point temperature, the lower the energy being utilized in HRSG which leads to a reduction of steam turbine power output. On the other side, an increase in pinch point temperature while fixing other design parameters, results in a decrease in heat transfer area for the HRSG component. This is why the total cost rate of the system decreases.Fig. 6.41a represents the effect of steam turbine isentropic efficiency (ηST) on both objective functions. An increase in ηST results in an increase in system exergy efficiency and increase in total cost of the system. Increasing this parameter results in an increase in the steam turbine power output, which directly leads to an increase in the exergy efficiency. It is also seen that increasing this parameter leads to an increase in steam turbine purchase and maintenance cost. Since an increase in this parameter has positive and negative effects on both objective functions, the variation of this design parameter within its allowable range exhibits a scattered distribution as shown in Fig. 6.37a. 151PDF Image | Energy Systems for Multigeneration Purposes
