... out within the MENA region on solar cooling technologies is presented. The solar cooling cycles reviewed are the adsorption, absorption, solid desiccant, liquid desiccant, ejector, and solar electric-driven cycles. The interest over time and across countries in each of these cycles is also discussed...

...Abdul Khaliq; Rajesh Kumar; Ibrahim Dincer; Farrukh Khalid In this paper, energy and exergy analyses of a new solar-driven triple-staged refrigeration cycle using Duratherm 600 oil as the heat transfer fluid are performed. The proposed cycle is an integration of absorption refrigeration cycle (ARC...

... factor for energy consumption reduction strategies and alternatives in the data centers. This paper presents a theoretical analysis of an absorption chiller driven by solar thermal energy as cooling plant alternative for data centers. Source primary energy consumption is used to compare the performance...

..., and use of the waste heat to operate a thermal process (absorption cooling). Appropriate optical and thermal energy losses are taken into account in all cases. The receiver temperature and the sunlight concentration level serve as free parameters. It is shown that concentrating the solar radiation...

...K. Gommed; G. Grossman, Faculty of Mechanical Engineering Technion,; F. Ziegler In earlier work, a novel open absorption cycle was proposed, capable of producing both cooling and dehumidification for air conditioning, utilizing low-grade heat. The system, referred to as DER (Dehumidifier-Evaporator...

... to the temperature of the heat source. The second term in the quotient of Eq. ( 1 ) arises from the absorption of the heat of vaporization of the liquid and is given by, ρ v . Δ H vap / ρ 1 − ρ v . The third term, p 1 / ρ 1 , in Eq. ( 1 ) arises from...

...Alejandro London˜o-Hurtado; Alejandro Rivera-Alvarez A model has been developed to study the behavior of Volumetric Absorption Solar Collectors (VASC) and the influence of the design parameters on the performance of the collector. The model’s approach is based on the use of several dimensionless...
