Free cooling of PV cells is a common research topic; it lowers the operating temperature cells, resulting in higher electricity production. This article investigated free techniques for wide range thermal properties PCM layer installed on backside cell. Two options were assumed: micro-encapsulated which heat transferred by conduction only, and macro-encapsulated transfer enhanced convection. Th...

Environmental temperatures that exceed body temperature (Tb) force endothermic animals to rely solely on evaporative cooling to dissipate heat. However, evaporative heat dissipation can be drastically reduced by environmental humidity, imposing a thermoregulatory challenge. The goal of this study was to investigate the effects of humidity on the thermoregulation of desert birds and to compare t...

Free cooling techniques can be used to substantially reduce energy costs. During cold weather, the outside ambient temperature can help in saving energy in refrigeration systems. The low temperature of the cooling ambient air supply enables free cooling technique to store fresh fruits and vegetables. This energy-efficiency measure can save enough compressor electric power to pay for modulating ...

Gas turbine inlet air-cooling (TIAC) is an established technology for augmenting gas output and efficiency, especially in hot regions. TIAC using evaporative cooling suitable hot, dry regions; however, the limited by ambient wet-bulb temperature. This study investigates two-stage under harsh weather of Riyadh city. The system consists indirect direct stages. In stage, air precooled water cooled...
