In contrast to standard vapor compression cooling systems, diffusion absorption refrigeration (DAR) systems are heat-driven and contain no moving parts. Solar can extract heat from a chamber without electricity, enabling food medicine be cooled in remote places where there is high solar radiation with unavailable or unreliable electricity. This work aims model the performance of solar-driven DA...

energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...

in this research multiple-regression analysis with stepwise selection method was employed for investigating the effectof vertical building envelopes solar radiation (evr) on cooling energy consumption (e cooling) in residential sector.the high capacity of solar energy in semi-arid climate (shiraz) can provide a part of buildings required energy. dependson house orientations in two directions of...

A solar driven cooling system consisting of a single effect H2O-LiBr absorbtion cooling module (ACS), a parabolic trough collector (PTC), and a storage tank (ST) module is analyzed during one full day operation. The pressurized water is used to transfer heat from PTC to ST and to feed the ACS desorber. The system is constrained to operate at the maximum ACS exergetic efficiency, under a time de...

In this paper a glass façade system is proposed, which controls the energy flows within the transparent building envelope [1]. Yearly energy consumptions of an office space are calculated in Munich and Dubai [2]. The office space is calculated with a theoretical glazing share of 100% within the south-west oriented façade area. A standard solar-control glazing unit (SCGU) is adopted as benchmark...
