A thermoeconomic analysis of a completely RPS powered by solar and geothermal sources is proposed.
5886 Exergy destruction kW 119. Functional diagram of the geothermal heat pump installation. In these units, the deviation between reactor outlet temperature and equilibrium temperature lies between 10 and 20 K.
The corresponding part of negentropy that each component uses is part of the resources, in this case virtual, that the component uses. Particular attention must be given to the kth component if the relative cost difference and cost rates are higher. A cost balance, on the other hand, expresses that the cost rate associated with the product of the system C P ; the cost rate equals the total rate of expenditures made to generate the product, namely, the fuel cost rate C F.
If the f k value is low, try to increase the capital investment for the selected component by increasing the component efficiency. The results from exergy analysis provide a base for an exergoeconomic analysis, an exergy-aided method to determine appropriate costs.
2, we will develop this method in more detail, applying it to a Rankine cycle. The function of the atmosphere is to redistribute this flow of gases, so that the boiler uses a flow of fresh air. Moreover, a parametric analysis is proposed in order to better understand the plant operating conditions once some key parameters have been varied, namely the environmental conditions, the temperature of the geothermal fluid entering the plant, the mass flow rate of geothermal fluid, and the scheduled time operation of the DHC network.
Remove any subprocesses that increase the exergy destruction or exergy loss without affecting the decreasing of capital investment or fuel costs for other components. Likewise, as in ECT, TFA also builds a functional model. 2 Aggregation level for applying exergy costing The level at which the cost balances are formulated affects the results of a thermoeconomic analysis. Each flow can be a thermodynamic flow or an economic flow, depending on the objective of the analysis.
After framing the aforementioned important variables and set of rules, the thermoeconomic evaluation of an energy system can be performed without compromising cost effectiveness. Its function is to transfer to the environment the entropy accumulated by the operation of the other components in the refrigerator.
Thus, the cost of the condenser is distributed Thermoeconomic analysis of environmental vapor power systems the other components of the installation, depending on the contribution of the other components to the production of entropy.
This is the type of model with which we usually work since it corresponds to what in the terminology of engineering we call a schematic diagram. In other words, in each iteration of the optimization, the relative cost difference must be lower than the first iteration. Even in such cases, we should make proper guesses to avoid the aggregation of the systems because it gives a lot of misleading information.
Thermoeconomic Analysis A thermoeconomic analysis performed for an absorption refrigeration system using the exhaust gas of a hydrogen-fueled diesel engine as energy source showed that engine combustion is the process with the highest exergy destruction, and that it is feasible to operate the system at intermediate and high engine loads Herrera et al.
the geothermal configuration, powered only by geothermal source case B.
Therefore, the components are connected by means of flows that can be subdivided into resource flows and product flows.
This concept of negentropy that has been explained with reference to a condenser is applicable to any dissipative equipment.
