TL;DR: In this paper, aqueous suspension based on alkaline functionalized carbon nanotubes was used as an absorber fluid in a direct sunlight harvesting device, where the intrinsic hydrophobic nature of carbon nanotsubes was overcome using a new dispersion procedure to prepare nanofluids.

TL;DR: In this paper, the cooling performance of two-stage indirect/direct evaporative cooling system is experimentally investigated in the various simulated climatic conditions, and the results show that more than 60% power saving could be obtained by this system in comparison with mechanical vapor compression systems with just 55% increase in water consumption with respect to direct evaporation cooling systems.

TL;DR: In this article, the performance of an indirect evaporative cooling system (IEC) to pre-cool air for a conventional mechanical cooling system has been investigated for four cities of Iran.

TL;DR: In this paper, a Direct Absorption Solar Collector (DASC) which used nanofluids with appropriate optical and heat transfer properties as absorbing medium, has been recently proposed.

TL;DR: In this article, the optical and thermophysical properties of CuO nanofluid as the working fluid of low temperature direct absorption solar collector which is prepared by dispersing the CuO nanoparticles into mixture of distilled water and ethylene glycol as the base fluid is investigated at the different temperatures for different volume fractions.
