Activated carbon (AC) of type Maxsorb III/HFC-134a pair has been examined as an adsorbent/refrigerant pair. FORTRAN simulation program is developed to analyze the influence of operating conditions (hot and cooling water temperatures and adsorption/desorption cycle times) on the cycle performance in terms of cooling capacity and COP. The main advantage of this two-stage chiller is that it can be operational with smaller regenerating temperature lifts than other heat-driven single-stage chillers. Simulation results shows that the two-stage chiller can be operated effectively with heat sources of 50{\^A}oC and 70{\^A}oC in combination with a coolant at 30{\^A}oC. {\^A}{\copyright} Published under licence by IOP Publishing Ltd.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84881106560&doi=10.1088\%2f1755-1315\%2f16\%2f1\%2f012084&partnerID=40&md5=b882e8ad4f469c63c1cca9cf6fa4e10f}, keywords = {Activated carbon; Adsorption; Cooling water; Waste heat, Adsorption chiller; Adsorption/desorption; Cooling water temperature; Cycle performance; Low-grade waste heat; Operating condition; Simulation program; Thermally driven, Cooling systems, activated carbon; adsorption; cooling; energy efficiency; performance assessment; regeneration; theoretical study} }
