| Popis: | A Theoretical and practical study was conducted to analyze the performance of a closed type parabolic trough collector CTPTC. The study was conducted in northern Iraq at longitude 43o.53 and latitude 35º.25. Use water as a working fluid at a mass flow rate of 0.00083,0.0011 0.00138, 0.00166, Kg/sec, with a concentration ratio of 10, 14 and 22. The maximum value of experimental efficiency of 42% in the summer and 29% in the Winter. The theoretical study was conducted according to ASHRAE 93-1986 (RA-91). The hypothetical results show that theoretical efficiency starts at 30% and increases relatively with increasing mass flow and decreases with temperature and the concentration ratio to reach a maximum value of 50%in the summer and a maximum value of 68% in the Winter. |
