“…Rodriguez Hidalgo et al [2] described an experimental research conducted on a 50 m 2 flat-plate solar collectors driven single-effect commercial LiBr/H 2 O absorption machine through a hot-water storage tank that produces 6-10 kW cooling power, with a generator driving power input of 10-15 kW, achieving a mean cooling period of 6.5 h of complete solar autonomy. The performance analysis and experimental results of 40 RT (1 RT D 3.517 kW which is the energy removal rate required to freeze one ton of water at 0°C in one day) cooling capacity water-lithium bromide absorption chillers for an office building run by 300 m 2 flat plate collectors, 20 m 3 of hot water reservoir and an oil-fired supplementary thermal energy source have been described by Ayyash et al [3].…”

Conventional cooling technologies that utilize harmful refrigerants consume more energy and cause peak loads leading to negative environmental impacts. As the world grapples with the energy and environmental crisis, there is an urgent need to develop and promote environmentally benign sustainable cooling technologies. Solar cooling is one such promising technology, given the fact that solar energy is the cheapest and most widely available renewable energy that matches the cooling load requirements. However thermal storage systems are essential to overcome the disadvantage of the intermittent nature of solar energy and variations in the cooling demand. The enhanced utilization of solar energy and other consequences of thermal storage integrated systems have gained the attention of researchers in recent years. The concept of combined sensible and latent heat storage system is successfully introduced in several applications and it has many advantages. This paper presents the performance of the solar collector system and the charging characteristics of a PCM based latent heat thermal storage unit, which is designed to provide continuous supply of heat for the operation of 1 kW vapor absorption refrigeration unit. Investigations on PCM integrated thermal storage system have revealed improvement in heat storage capacity, lower heat loss and an increased solar collector efficiency due to better thermal stratification.
