...Andre Bolt; Branson Chea; Ibrahim Dincer; Martin Agelin-Chaab; Marc Rosen In this paper, a multigeneration system is proposed, which utilizes geothermal energy and a lithium-bromide absorption cooling cycle. The proposed system is capable of providing electricity, heating, cooling, and domestic hot...

...Bengt Sunden; Zan Wu Control of heat transfer is important in wind power systems. In cold climate, the problems of icing and de-icing of the turbine blades need to be handled by efficient heat transfer technologies. Heat-generating components like electric generator, gear box, and frequency...

...Harumi Toriyama; Yutaka Asako The effect of a permanent magnet on ventilation of an air duct through compost has been investigated numerically. Some composts yield heat over 60 ° C in the fermentation process. This exothermic reaction produces a considerable amount of heat, which could...

...Lubomir A. Ribarov; David S. Liscinsky Cooling, heating, and power (CHP) energy systems provide higher fuel efficiency than conventional systems, resulting in reduced fuel consumption, reduced emissions, and other environmental benefits. Until recently the focus of CHP system development has been...

...Sriram Somasundaram, Program Manager, Technology Systems Analysis, Fellow ASME; David W. Winiarski; David B. Belzer PNNL, under direction from DOE, conducted a screening analysis to determine the energy savings potential from the efficiency levels for commercial HVAC and water-heating equipment...

... under both rapid heating and slow heating conditions were measured using a high-volatile bituminous coal and a medium-volatile bituminous coal. The significant difference in reactivity between rapid heating chars and slow heating chars, and the decrease of char reactivity at high temperature were...

... . The single fuel particle underwent devolatilization and char combustion while it was fluidized in the bed of silica sand. The fluidized bed of silica sand around the fuel particles provided an even temperature distribution around the fuel particle and a good heat transfer to the fuel particle. With the FTIR...
