In tropical and subtropical regions, air-conditioning is employed throughout the year, which poses a significant challenge to the designer in reducing its energy consumption. Buildings in these regions would have latent load that is large enough throughout ...
Impingement cooling is widely used in the cooling of turbine airfoils at critical regions where high heat transfer rates are required due to the large local convection coefficients that can be achieved. An accurate determination of local heat transfer dist ...
This report presents the work done in the frame of a Minor in Energy project in the school of Mechanical Engineering at the Swiss Institute of Technology of Lausanne (EPFL), in order to obtain 10 ECTS credits. It is to install, instrument and test an exhau ...
Small-scale turbomachines in domestic heat pumps reach high efficiency and provide oil-free solutions, which improve heat-exchanger performance and offer major advantages in the design of advanced thermodynamic cycles. An appropriate turbocompressor for do ...
This study investigates the potential for energy and water sustainability in hot and humid climates by utilizing the condensate captured from large dedicated air handling units (AHUs) for pre-cooling outdoor air in another AHU and subsequently offsetting c ...
Process integration methods allow one optimizing industrial processes. The main goals are decreasing energy demand and operating costs as well as reducing pollutants emissions. High fuel costs promote installations of heat pumps. In a heat pump, process wa ...
