Photovoltaic systems are increasingly being used in residential buildings. The absorbed heat of PV panels is normally dissipated to the ambient air via a natural convection and radiation.

The photovoltaic thermal (PV/T) driven desiccant air cooling process could be a good solution to the conventional air cooling cycle in terms of energy saving, where the latent cooling load would be removed adiabatically. However, problems exist where the required desiccant regeneration temperature (60oC - 80oC) often exceeds the outlet fluid temperature from standard PV/T collectors.

High-temperature absorption chillers (double-effect and triple-effect) have a higher coefficient of performance (COP) than single-effect chillers. This can reduce the collector’s footprint and cost in a solar-cooling plant. Though single-effect, absorption chiller-based solar-cooling systems have been studied for the past 20 years, very little information is available on the performance benefits of high-temperature solar-cooling systems.
