| Abstract | Popularity of solar cooling techniques is increasing due to its environmental friendliness and its use of renewable energy, leading to reduction in capital investment cost. In this study, hourly simulation will be done on a model of small solar powered 4.7kWth absorption chiller, and a model of PV-driven 7.1kWth electrical chiller. For absorption chiller, 2 scenarios will be considered, one where the hot water is left in collectors to cool down during OFF hours, and another where hot water from the collectors will be drained back to store the thermal energy. Furthermore lifecycle costs were calculated for economic comparison of the systems. Simulation results show that the modeled systems are able to provide cooling, and the lifecycle costing shows, that for small size systems, grid operated chiller is more economically feasible than a solar powered absorption chiller and PV-driven electric chiller. |
