Evaluation of Evaporative Cooling for Heat Transfer in the Condenser of Window-Air Conditioners
There is a demand for reduced power consumption in the vapor compression refrigeration cycle. Coefficient of performance of window-air conditioners considerably decreases and power consumption increases under very hot conditions. These problems have encouragecl studies aimed at improving the performance of window-air-conditioners by enhancing the heat transfer rate in the condenser. In this ar...

متن کاملReview of engine cooling technologies for modern engines
The performance of the conventional engine-cooling system has always been constrained by the passive nature of the system and the need to provide the required heat-rejection capability at high-power conditions. This leads to considerable losses in the cooling system at part-load conditions where vehicles operate most of the time. A set of design and operating features from advanced enginecoolin...
متن کاملImproving the Cooling Process of Heavy-Duty Engines through Three Dimensional Simulation of Fluid Flow in its Coolant Centrifugal Pump
This paper investigates 3D simulation of fluid flow in a centrifugal pump from the Detroit Diesel company to extract possible engine cooling trends. The velocity and pressure profile of water, the coolant, is analyzed and the characteristic curves of the pump are derived. This provides a useful evaluation of the pump performance at all working conditions. For this aim, a computational fluid dy...
متن کاملAir cooling of a microelectronic chip
A single-mask process is used to fabricate metal microchannels of 5–10 μm in width, 10–40 μm in height and millimeters in length, monolithically (i.e., no bonding) on the chip front side. Taking advantage of the small size and the diverging cross-section allowed for these microchannels, we explore the air cooling of a microelectronic chip, addressing the limitations of the liquid cooling with t...
