“…External irreversibility found in heat conduction, mass transfer, friction, eddy and others. Moreover, internal irreversibility such as (heat engine cycle/generatorabsorber and refrigeration cycle/evaporator-condenser) has higher impact on reducing the performance [50]. Fathi et al studied the impact of irreversibility in solar absorption refrigerator by using four reservoir models each of them has internal and external irreversibilities operated at the maximum cooling load [51].…”

“…Also, internal irreversibility such as heat engine cycle/generator-absorber and refrigeration cycle/evaporator-condenser has higher impact on reducing the performance. 61 Fathi et al 62 studied the impact of irreversibility on solar absorption refrigerator by using four reservoir models; each of them has internal and external irreversibilities operated at the maximum cooling load. They compared their modeling results with single-stage system using semi-empirical model.…”

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.

“…The corresponding optimum values of the internal temperatures t i calculated from Eqs. (6) to (9) are communicated to the model of the absorption cycle (described in Section 5) which calculates the corresponding new values of T i , a d and x cr h b cr /(b a þ b cr ) along with other results. The new value of j is then calculated from Eq.…”
