Design and Development of Prototype Cylindrical Parabolic Solar Collector for Water Heating Application

Abstract

Concentrating collectors absorbs solar energy and convert it into heat for generating hot water, steam at required temperature, which can be further used for solar thermal applications. The developing countries like India where solar energy is abundantly available; there is need to develop technology for harnessing solar energy for power production, but the main problem associated with concentrating solar power technology is the high cost of installation and low output efficiency. To solve this problem, a prototype cylindrical parabolic solar collector having aperture area of 1.89 m2 is designed and developed using low cost highly reflecting and absorbing material to reduce initial cost of project and improve thermal efficiency. ASHRAE Standard 93, 1986 was used to evaluate the thermal performance and it was observed that this system can generate hot water at an average temperature of 500C per day with an average efficiency of 49% which is considerable higher than flat plate solar collectors. Hot water produced by this system can be useful for domestic, agricultural, industrial process heat applications.Article History: Received Sept 19, 2015; Received in revised form Dec 23, 2015; Accepted February 2, 2016; Available online How to Cite This Article: Bhujangrao, K.H.

Thermal Performance Analysis of Parabolic Trough Solar Concentrator with Helical Tube Receiver

“…The experimental results were recorded every 1 hour and the thermal performance was presented in Figs. (8)(9)(10)(11)(12)(13)(14) for different days at the same flow rate of water. Fig.…”

“…The results in Figs. (9)(10)(11) show that when using the helical tube, the output temperature, useful heat gain and thermal efficiency increase by 27.3%, 29.6% and 35.2%, respectively as compared with the straight tube. Therefore, it can be concluded that the helical tube with tracking system is more efficient than the straight tube.…”

Design of Solar Water Heater Using Collector Cylindric Parabolic and Coil Heater as Absorber at Focus Point

“…where N is the number of coils turns The concentration ratio is an important parameter to describe the amount of solar energy that can be concentrated by a parabolic cylinder collector. The geometric concentration ratio is defined as the ratio between the area of the collector opening and the surface area of the coil pipe (absorber), calculated using the following equation [17]:…”

SWHEI: A New Approach to Measure Policy Effectiveness for Solar Water Heaters

“…This indicator, the Solar Water Heater Effectiveness Indicator, or SWHEI, is based on equipment deployment (installed capacity per capita, installed capacity growth) and the solar energy potential of each country. The indicator is constructed using A significant body of research focuses on the technoeconomic and life-cycle analysis of SWH technologies (Li, Tzameret, & Onyina, 2012;Chang K. , Lin, Lee, & Chung, 2008;Chang K. , Lin, Lee, & Chung, 2009;Huang, Castán Broto, & Liu, 2018;Baccouche, 2014;Handayani & Ariyanti, 2012;Kulkarni, 2016;UNEP, 2015). However, there are fewer research papers related to measuring the effectiveness of public policies that are aimed at increasing the deployment of renewable energy, much less that of SWH (Puig & Morgan, 2013;Chang, Ho, & Hsu, 2013;Held, Ragwitz, & Haas, 2006).…”
