The thermal performance of proposed model deals with combined double bed vapor adsorption refrigeration system and 9MW of Rankine thermal cycle .The provision of evacuated tube type solar collector (ETC) is available with adsorption system to support the system for continuous cooling effect. The energy-exergy analysis refers live operational data of thermal power plant, and proposed cooling system is adopted as per thermal gain from condenser and solar heater for adsorbent-adsorbate pair of adsorption system. Major units of combined plant (boiler, turbines, condenser, pump, solar collector, adsorption bed etc.) have been investigated in thermodynamic analysis. The main objective of energyexergy modeling is to identify the magnitude of process, cause of losses and rectifying the components. The source temperatures available for both beds of Vapor Adsorption Refrigeration systems (VAdRS) from condenser exhaust and ETC solar system. The adsorbent and adsorbate pair for double bed VAdRS has been recommended by activated carbon as adsorbent and methanol and R134a as adsorbate respectively. This analysis shows the combination of adsorbentadsorbate pair is suitable for low grade heat recovery with solar thermal integration for continuous cooling effect generation and applicable for space cooling purpose. The major findings of present work, the maximum irreversibility found in boiler as 47% in thermal power plant and solar generator as 12% of adsorption machine, whereas overall cooling effect from adsorption system is increasing by 15% in double bed combination. EES software is used for all analysis.
