Two cooling methods are installed in the cooler synchrotron COSY. The electron cooler is used for stacking and cooling of proton beams with energies between 45 MeV and 180 MeV. After last year’s commissioning the stochastic cooling system became a standard tool for beam cooling in the momentum range of 1.5-3.3 GeV/c. The stochastic cooling pickups also serve for precision measurements of the ch...
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...
A novel solar-based combined system which is consisting of a concentrated PV, a double effect LiBr-H2O absorption chiller, and a Proton Exchange Membrane (PEM) is proposed for hydrogen production. A portion of the received energy is recovered to run a double effect absorption chiller and the rest is turned into electricity, being consumed in the PEM electrolyzer for hydrogen producti...
Although water-cooled chillers are more energy efficient than air-cooled chillers, a majority of chilled water systems use air-cooled chillers. In cold weather climates, air-cooled chillers are capable of functioning in low ambient temperatures with few operational concerns, where as water-cooled chiller systems must be equipped to prevent cooling tower freezing. The integrated chiller system a...
یکی از روشهای متداول برای جلوگیری از تغییر شکل و خواص قطعات در تماس با گازهای داغ، از قبیل پره توربین و دیواره محفظه احتراق، استفاده از تکنیک سرمایش لایه ای (film cooling) می باشد. در روش سرمایش لایه ای شکافی (slot film cooling) سیال خنک کن مانع مانع از انتقال حرارت بین گازهای داغ و سطح فلز می شود. در این حالت می توان تحلیل جریان را به صورت دوبعدی انجام داد. اما در روش سرمایش لایه ای تک سوراخه ...
