| dc.description.abstract | Solar energy is one among the abundantly available renewable energy resources. The simplest and most direct application of this energy is the conversion of solar radiation into heat, which can be used in water heating systems. One of the weaknesses of this solar energy supply is its intermittent characteristic. Therefore, solar energy needs integrated with thermal energy storage. This work presents the system design, fabrication and experimental analysis of Compound Parabolic Solar Collector (CPSC) integrated with phase change material (PCM). The collector is used to heat the water and the PCM used to store the heat during the day and convert heat water during the night time. Bees wax was selected as PCM based on the melting temperature range, availability and other properties. A compound parabolic solar collector of aperture area of 0.82m×1.5m with concentration ratio of 3.86 has been designed and the experimental analysis with and without phase change material was conducted. The experimental tests have been carried out in open field located at Bahir Dar Institute of Technology during selected days of the months of June 2017. The water temperature, glass temperature, absorber plate temperature, ambient temperature, PCM temperature, and solar intensity was measured and recorded every 30 minute. The experiment test started from 8.00 AM to 4:00 PM. The results show that the maximum temperature of the collector integrated with PCM at 12:00 AM was 74°C. During the experiment the maximum temperature of bees wax produced by collector was observed 60°C. The daily average efficiency of a solar collector with PCM and without PCM was 56.31% and 50.1% respectively. Based on experimental results, by adding of bees wax in the solar collector could able to increase efficiency of solar water heating systems. | en_US |
