The study investigated the cycle optimization of four-hex, silica gel-water adsorption with re-heat cycle, which is desorber (upper–hex) and adsorber (lower-hex) always interact with condenser and evaporator, to exploit low heat source temperature. A photovoltaic system designed and implemented in order to produced hot water which is used as solar driven or heat source in the adsorption refrigeration cycle. In this paper, the working principle of re-heat cycle introduced and a simulation model of re-heat adsorption cycles has developed as well. The optimization of the cycle time including adsorption/desorption time, mass recovery time and pre-heating/pre-cooling time, with chilled water outlet temperature fixed has observed during simulation. The proposed cycle was compared with the four-hex without re-heat cycle in terms of COP and cooling capacity and will be the performance indicator of the cycle. The result shows that the performance of re-heat cycle is superior to that of four- hex without re-heat especially for low heat source temperature. For low heat source temperature (55-65oC) both COP and cooling capacity of re-heat cycle with optimization raised significantly compared to the high heat source temperature (70- 80 oC)
