Abstract

Commerical solar absorption systems are now available for residential space cooling purposes. We have undertaken a cost analysis, based on a detailed simulation procedure, of a two-ton system to cool a proposed residence in Kufra, Libya. The meteorological data used for this study are measured daily insolation, ambient temperature and humidity records for an entire cooling season. The performance curves of the absorption chiller, cooling tower and collector, reported by the manufacturer have been modelled. These are used for the determination of hourly generator and storage temperatures. Finally, various energy transfers and seasonal solar fractions are obtained. Analysis is made by comparing the actual costs of a solar absorption cooler with those of a conventional vapour-compression machine. The results showed that the solar system is still more expensive than the conventional system. However, the potential of the absorption system to offset twice the cooling load of its rated capacity, which is manifest in dry, arid conditions, makes it economically competitive in addition to conserving 50 per cent of fossil fuels.
