A three-dimensional numerical analysis was conducted to examine the effect on performance of un-balanced heating/cooling water supply and nonuniform pressure distribution in the beds, issues observed in an experiment by our colleague during the development of a 35 kW prototype finned-tube type adsorption chiller. Case studies were conducted with reference values of v=1m/s, Pc=4144 Pc=4144Pa and Pe=1447 Pa, and the differences in Δv=0.25 Δv=0.25m/s, Δ c =415 ΔPc=415Pa and ΔP e =145 ΔPe=145Pa. A remarkable increase in COP was found for the cases of un-balanced heating water supply and nonuniform pressure distribution when the bed was connected to the evaporator. However, after integration of multi-modules, the effect was smoothed out, which removed the worry about the degradation in the overall COP. The effect of un-balanced cooling water supply and nonuniform pressure distribution when the bed was connected to the condenser was not discernible. In all cases, the change in SCP was negligible.
