The potential applications and advantages of powering solar air-conditioning systems using concentrator augmented solar collectors

► The ETHPA recorded a 4.53% higher optical efficiency compared to the CAETHPA. ► An overall improvement of 24% in heat loss coefficient was realised by the CAETHPA compared to the ETHPA. ► Crossover in efficiency occurs at abscissa values of 0.10 Km2 W−1 in favour of the CAETHPA compared to the ETHPA system. ► The total energy collected represents a 17% improvement recorded by the CAETHPA compared to the ETHPA. ► The use of a CAETHPA is a more economical alternative for meeting the heating and cooling demands.
