A large-diameter aluminum-alloy finned-tube absorbent bed collector was designed and optimized by enhancing the heat and mass transfer in the collector. The collection efficiency of the adsorbent bed collector was between 31.64% and 42.7%, and the temperature distribution in the absorbent bed...

Solar space cooling is important in the countries of the Arabian Peninsula where nearly half of the total produced electricity is used for air conditioning of residential commercial and public buildings. In Kuwait, large proportion of funds were allocated for research in solar cooling...

This paper presents a systematic energetic, economical, and environmental assessment on a solar cooling system for a medium-sized office building in Los Angeles, California by means of system modeling. The studied solar cooling system primarily consists of evacuated tube solar collectors, a hot...

Since July 2008, a Solar Desiccant Evaporative Cooling (DEC) system has been operating as a test plant at the solar laboratory of the Dipartimento di Energia (ex DREAM) of the University of Palermo. The system is composed of an air handling unit (AHU) designed for ventilation of the laboratory...

The transient state heat transfer formulation has been used to determine the air conditioning cooling load for two selected one room buildings in Khartoum: one made from brickwork and the other from wood. This formulation has been achieved by applying an explicit finite difference numerical...

This paper presents an experimental work relating the thermodynamic efficiency of jet compressors to the compression ratio of the corresponding cooling cycle. The working fluid used in the experimental work was R-114 for both motive and suction sides. Two jet compressors, designed to operate at...

This paper presents a novel and innovative solar cooling, air-conditioning process for individual buildings, which uses common flat plate collectors. The principle of the process is based on an original coupling between an engine cycle and a reverse cycle, which are respectively a Rankine-like...

Simulation study of a solar adsorption refrigeration system using a wing type compound parabolic concentrator (CPC) is presented. The system consists of the wing type collector set at optimum angles, adsorption bed, a condenser and a refrigerator. The wing type collector captures the solar...

In this paper a review of solar cooling and refrigeration technologies is presented. A discussion on the main reasons why these technologies are not presently economically feasible is carried out. and two installations in Mexico are analysed.
