This paper addresses the problem of reducing energy consumption in buildings by using a new hybrid solar-assisted air conditioning (HSAC) system taking into account indoor air quality. Based on the refined models of system components, the influence of integrated vacuum solar collector and solar storage tank on the system performance is discussed in terms of energy savings and human comfort. For this purpose, the system is retrofitted with several sensors and datalogger devices to record the system performance data. The mathematical models and experimentally-collected data are coded into a transient simulation tool. The integrated simulation tool is validated through testing conditions during a summer period. Results are provided to show the capability of significantly reducing electricity consumption while ensuring comfort enhancement by using the proposed system.
