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...

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...

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.

Renewable energy based technologies can be introduced for building cooling applications. Most studies on solar absorption cooling use fossil energy based auxiliary heaters. This paper presents experimental studies of a solar-biomass hybrid air conditioning system. The system performances at...

Solar sorption refrigeration technologies are regarded as a promising way to meet the growing refrigeration needs in Africa, for thermal comfort, foods and crops, vaccines and medicines conservation. Sorption technologies projects and studies have been reported in Africa since the late 1970s....
