Assessing the performance of the evacuated tube solar collector using smart curtain through (PSO based PID)‎ controller and nano fluids

Abstract EN

This research revealed control on Nano fluid temperature in the evacuated tube solar collector system, where Nano fluids used in ETSC as working fluid to increase heating system thermal efficiency.

Smart curtain was used to shadow the evacuated tube solar collector and to control the temperature of the Nano fluid in heating or cooling condition which is moved by the stepper motor which is programmed to move through the Arduino board using an artificial intelligence method such as (PSO based PID) controller method .

Where the curtain's main idea is to control the polarization of the sun's radiation, the work of the curtain refers to the parameters: the first parameter is the Nano fluid temperature and the second is sun radiation falling on the collector, and one output parameter is defined by (distance parameter).
