Abstract
This work constitutes the thermal analysis of parabolic trough solar collector (PTC) in order to obtain its necessary geometry as function, mainly, of the required thermal load and temperature. For this, a mathematical model was developed and an algorithm for numerical simulation performed in Matlab® software, was generated. The model was tested with theoretical and experimental studies getting a PTC length maximum deviation of 7.44 %. In addition, it was analyzed the PTC geometry sensitivity according to vacuum condition, solar radiation, heat transfer fluid mass flow rate, thermal load, reflector width and heat transfer fluid type. Finally, the model was applied to a 1 RT ammonia-water absorption refrigeration cycle obtaining a necessary length of 11.7 m for 1 m reflector width.
