Thermoeconomic optimization of a heat pump system

Thermoeconomic Lifecycle Cost Optimization of an Annular Fin Heat Exchanger

In this paper the design of annular fin heat exchanger based on economic optimization has been carried out. The optimization process targeted minimizing the lifecycle cost of annular fin heat exchanger that has the same frontal area, effectiveness and heat load of available practical standard geometry exchangers. The lifecycle cost includes both capital and operating costs. Beside the pumping c...

Thermoeconomic analysis of a low-temperature multi-effect thermal desalination system coupled with an absorption heat pump

This study presents a thermal and economic performance analysis of a LT-MEE (low-temperature multieffect evaporation) water desalination system coupled with an LiBreH2O ABHP (absorption heat pump). A 60e78% water production increase over a stand-alone LT-MEE run at the same heat source conditions can be obtained owing to the coupling. A detailed thermodynamic sensitivity analysis of the ABHP-ME...

Finite-Time Thermoeconomic Optimization of a Solar-Driven Heat Engine Model

In the present paper, the thermoeconomic optimization of an irreversible solar-driven heat engine model has been carried out by using finite-time/finite-size thermodynamic theory. In our study we take into account losses due to heat transfer across finite time temperature differences, heat leakage between thermal reservoirs and internal irreversibilities in terms of a parameter which comes from...

Modeling Convective Heat Transfer in a Geothermal Heat Pump System

Optimization Of A Heat Pump For Satellite Cooling

In recent years the heat fluxes that must be removed from terrestrial electrical systems have been steadily increasing. The same increase in electrical component heat flux can also be seen in satellite and aerospace applications. As a result, it has proven necessary to develop heat pump systems that can operate in low-gravity environments with high reliability and efficiency to cool electrical ...
