...-called cavity depth). When the sizes of the inlet and outlet openings are the same, the effects on the decrease of cell temperature are limited. By enlarging the bottom (inlet) opening, the impact of ventilation in the cavity behind is more significant and the cell temperature decreases. Cavity depth...

...A. Ganguly; S. Ghosh In this paper, the performance analysis of a floriculture greenhouse having a fan-pad ventilation system is presented. The greenhouse is powered by integrated solar photovoltaic–electrolyser–fuel cell system. Electrical energy is generated in an array of roof mounted solar...

... flux through the outlet vent equals that of the buoyancy source. Both rooms remain stratified with two-layer weak stratification in this case, with a mean density that decreases as the size of the outlet increases. The implications for ventilation are discussed. Bolster , D. , and Linden...

...Lara V. Greden; Leon R. Glicksman; Gabriel Lopez-Betanzos The variable, uncertain nature of climate imposes risk in using solar and building technologies, such as natural ventilation (NV). To maximize the potential benefit from NV while reducing risk, a building could be designed for NV along...
