Abstract Conventional desalination technologies like multi stage flashing, multi-effect desalination (MED) using steam as motive fluid can be made sustainable by obtaining the motive steam from solar thermal systems. In this study, a transient simulation has been performed to determine the dissimilitude in pressure drop and dryness fraction, of working fluid in absorber tube due to variation in solar irradiance. A one-dimensional (1D) mathematical model has been developed using matlab for assessing the thermal performance and heat transfer characteristics of a direct steam generating (DSG) parabolic trough collector (PTC) system. It was observed that maximum pressure drop does not occur at maximum quality indicating the working conditions impair the system performance. The developed model was used to overcome this by varying both pressure and mass flowrate of working fluid in accordance to the radiation, results indicated reduction in pressure drop during the same time period for the same exit quality.

The current study presents a numerical and real-time performance analysis of a parabolic trough collector (PTC) system designed for solar air-conditioning applications. Initially, a thermodynamic model of PTC is developed using engineering equation solver (EES) having a capacity of around 3 kW. Then, an experimental PTC system setup is established with a concentration ratio of 9.93 using evacuated tube receivers. The experimental study is conducted under the climate of Taxila, Pakistan in accordance with ASHRAE 93-1986 standard. Furthermore, PTC system is integrated with a solid desiccant dehumidifier (SDD) to study the effect of various operating parameters such as direct solar radiation and inlet fluid temperature and its impact on dehumidification share. The experimental maximum temperature gain is around 5.2°C, with the peak efficiency of 62% on a sunny day. Similarly, maximum thermal energy gain on sunny and cloudy days is 3.07 kW and 2.33 kW, respectively. Afterwards, same comprehensive EES model of PTC with some modifications is used for annual transient analysis in TRNSYS for five different climates of Pakistan. Quetta revealed peak solar insolation of 656 W/m2 and peak thermal energy 1139 MJ with 46% efficiency. The comparison shows good agreement between simulated and experimental results with root mean square error of around 9%.
