In this study, the thermal performance of an internal heat exchanger-organic flash cycle system driven by geothermal water was investigated. The R600a/R601a mixtures were selected as working fluid. effects mole fraction on absorption capacity heater, temperature rise cold fluid in exchanger, net power output, efficiency, and electricity generation costs analyzed. outputs, costs, efficiency simp...

The anion exchanger Pendrin, which is encoded by SLC26A4 (human)/Slc26a4 (mouse) gene, is localized on the apical membrane of non-acid-secreting intercalated (IC) cells in the kidney cortical collecting duct (CCD). To examine its role in the mediation of bicarbonate secretion in vivo and the apical Cl(-)/HCO(3)(-) exchanger in the kidney CCD, mice with genetic deletion of pendrin were generated...

This report describes initial efforts to map the ankyrin-binding site of the cytoplasmic domain of the human erythrocyte anion exchanger. The conclusions are that this site is likely to involve a fairly extended sequence in the midregion of the cytoplasmic domain and requires interactions that are not provided by isolated peptides. The region of the sequence involving residues 174-186 is likely...

this paper presents a simple methodology for cost estimation of a near optimal heat exchanger network, which comprises mixed materials of construction. intraditional pinch technology and mathematical programming it is usually assumed that all heat exchangers in a network obey a single cost model. this implies that all heat exchangers  in a network are of the same type and use the same materials...

The performance of the two types of vapor-injection (VI) cycles in a heat pump system is compared. The vaporinjection cycle using an internal heat exchanger (IHX) has a choice to select the branching point of the injection stream. The two VI cycles are different in terms of branching points of the injection stream. Different branching points of the injection stream influence the heating capacit...

In this work, numerical simulation calculations were performed to investigate the minimum ground temperature that occurs when extracting thermal energy in a horizontal heat exchanger system Central European climate. The influence of conductivity, flux extracted from ground, periodic interruptions operation exchanger, supply relative humidity ambient air, evaporation rate coefficient, and convec...
