The current study presents a numerical and real-time performance analysis of a parabolic trough collector (PTC) system designed\nfor solar air-conditioning applications. Initially, a thermodynamic model of PTC is developed using engineering equation solver\n(EES) having a capacity of around 3 kW. Then, an experimental PTC system setup is established with a concentration ratio of\n9.93 using evacuated tube receivers. The experimental study is conducted under the climate of Taxila, Pakistan in accordance\nwith ASHRAE 93-1986 standard. Furthermore, PTC system is integrated with a solid desiccant dehumidifier (SDD) to study the\neffect of various operating parameters such as direct solar radiation and inlet fluid temperature and its impact on\ndehumidification share. The experimental maximum temperature gain is around 5.2�°C, with the peak efficiency of 62% on a\nsunny day. Similarly, maximum thermal energy gain on sunny and cloudy days is 3.07kW and 2.33 kW, respectively.\nAfterwards, same comprehensive EES model of PTC with some modifications is used for annual transient analysis in TRNSYS\nfor five different climates of Pakistan. Quetta revealed peak solar insolation of 656W/m2 and peak thermal energy 1139 MJ with\n46% efficiency. The comparison shows good agreement between simulated and experimental results with root mean square error\nof around 9%.
