Theoretical investigation of the Effect of mass flowrate on PTC performance

Abstract

The objective of this paper is to study the performance of TPC. A theoretical study was conducted to examine the Effect of mass flow on PTC performance. It was done at the Renewable Energy Unit in Hawija, Iraq. Use water as working fluid WF at a mass flow rate of 0.00083.0.0011 0.00138, and 0.00166 Kg/s. The concentration ratio of 10, 14, 18 and 22 are used. This theoretical investigation was carried out by ASHRAE 93-1986 (RA-91). The results indicate that the theoretical efficiency starts at 40% in summer and increases relatively as mass flow increases to a maximum value of 6% in Winter. Moreover, the results demonstrated that efficiency is inversely related to concentration ratio and temperature. The performances of TPC in spring and autumn are convergent.
