“…91,92 The solar adsorption cooling consists mainly of solar collector array, heat storage tank, chillers, pumps, fan coil unit, cooling tower, and several valves as shown in Figure 2(b). The chiller mechanism is explained in Alghoul et al, 84 Ge et al 92 and Wang and Oliveira. 93 The adsorption chiller has been designed using one bed, two beds, or multi-beds.…”

Solar thermal cooling is the best alternative solution to overcome the problems associated with using nonrenewable resources. There are several thermal cooling methods developed differing from each other according to the thermodynamic cycle and type of refrigerant used. Recent developments in absorption and adsorption solar cooling systems are presented. Summarized thermodynamic modeling for both absorption and adsorption solar cooling systems is given. Brief thermal analysis among the types of solar collectors is presented. System efficiencies and optimization analysis are presented. The influences of geometrical, system configurations, and physical parameters on the performance of solar thermal sorption cooling system are investigated. The basis for the design of absorption and adsorption solar cooling systems is provided. Several case studies in different climatic conditions are presented. Economic feasibility for both systems is discussed. Comparison between the absorption and adsorption solar cooling system is summarized.

“…Two main parameters can be used to evaluate the performance of adsorption refrigeration: the coefficient of performance (COP) and specific cooling power (SCP). The COP value of the intermittent adsorption refrigerator varies from 0.01 to 0.2 depending on the collector efficiency (Alghoul et al, 2007;Anyanwu, 2004). The coefficient of performance is defined as the ratio of the total heat extracted by evaporation of the desorbed mass of the methanol (kJ) to the total incident global irradiance from sunrise to sunset can be written as in equation (Li et al, 2005;Parash et al, 2016) (6) where ∫ i(t) dt is total incident global irradiance .…”

This study investigates the performance of a solar adsorption refrigerator using activated alumina and methanol adsorption pair. The experiments were carried out for 24-hour. The refrigeration was completed during seven cycles with varying weather conditions. A flat plate type collector was used with an area of 0.25 m 2 and tilt angle of 30 o . Theoretical calculations show that, the maximum collector efficiency is 47.15% when the maximum solar radiation obtained is 936.9 W/m 2 . In this research, the maximum value of the COP is 0.0991 when the total solar energy is 16.485 MJ/m 2 and the minimum value obtained is 0.0919 when the total solar energy is 7.609 MJ/m 2 . The experiment results show that the adsorption pair system can deliver an evaporator temperature of about 9.92°C and the cooling load can be achieved by a heat source with a temperature range of 83.95°C and 95.39 o C.

“…Intermittent vapor absorption refrigeration plants work on a 24 h cycle comprising heating and refrigeration processes matched to the diurnal operation of the sun: undergoing heating process during the day and producing 'cooling' at night [99]. Porous solids, termed adsorbents, can physically and reversibly adsorb large volumes of a vapor, termed the adsorbate.…”
