A review and recent developments in photocatalytic water-splitting using TiO2 for hydrogen production
TL;DR: In this article, the up-to-date development of the above-mentioned technologies applied to TiO 2 photocatalytic hydrogen production is reviewed, based on the studies reported in the literature, metal ion-implantation and dye sensitization are very effective methods to extend the activating spectrum to the visible range.
Journal ArticleDOI
Technology development in the solar absorption air-conditioning systems
Z.F Li,K. Sumathy +1 more
TL;DR: In this paper, the authors reviewed past efforts in the field of solar powered air-conditioning systems with the absorption pair of lithium bromide and water and found that the generator inlet temperature of the chiller is the most important parameter in the design and fabrication of a solar-powered air conditioning system, while collector choice, system design and arrangement are other impacting factors for the system operation.
Journal ArticleDOI
Solar transparent insulation materials: a review
N.D. Kaushika,K. Sumathy +1 more
TL;DR: In this article, the authors present a status report on solar transparent insulation materials (TIM), which covers a survey of the literature, various physical and other properties of TIM devices, their classifications, applications, fabrication procedures, availability and cost trends.
Journal ArticleDOI
Study on a direct-expansion solar-assisted heat pump water heating system
Y.H. Kuang,K. Sumathy,Ruzhu Wang +2 more
TL;DR: In this paper, an analytical and experimental studies were performed on a directexpansion solar-assisted heat pump (DX-SAHP) water heating system, in which a 2 m2 bare flat collector acts as a source as well as an evaporator for the refrigerant.
Journal ArticleDOI
Theoretical study on a cross-flow direct evaporative cooler using honeycomb paper as packing material
Yanjun Dai,K. Sumathy +1 more
TL;DR: In this article, a cross-flow direct evaporative cooler, in which the wet durable honeycomb paper constitutes as the packing material, is investigated, and the system is expected to act as both humidifier and evaporation cooler to create a comfortable indoor environment in arid regions.
