Expert Control Strategies for Solar Cooling systems
… sector amounted at 36%. Space heating and cooling is the most significant component of household energy demand. The European Directive to promote renewable heating and cooling requires that 25% of EU heating and cooling to be supplied by renewables in 2020. In the building sector, a high …

A THERMO-ECONOMIC STUDY OF SOLAR COOLING/HOT WATER SYSTEMS
Solar air-conditioning appears to be uneconomical as the collectors tend to remain "idle" for significant operating periods owing to high collector output temperature requirements for absorption cooling. The performance could be improved by incorporating a water heating loop in the basic cooling …

The architectural implications of passive solar cooling systems in hot-arid climates
… first is its unusually hot-arid climate (thus cooling interior spaces becomes a crucial design consideration). and the second is its multi-dimensional urban identity. The city is a mixture of African, Arab, and European influences and resembles at the same time an oasis in the middle of the …

Solar desiccant evaporative cooling with multivalent use of solar thermal heat
Solar DEC (Desiccant and Evaporative Cooling) air-conditioning is a renewable technological approach to the future air-conditioning of buildings driven with solar-thermal heat. The principal acceptance of solar airconditioning has led to system prototypes mainly across Europe, however the diffusion …
