Abstract

An experimental investigation of parabolic dish solar cooker for exergy analysis is presented in this study. The experiments were carried out using 3 litres of water as cooking fluid. Commercially available parabolic dish domestic concentrator (SK14) was used to focus the solar radiations whereas a blackened cooking vessel was used as a receiver. The average ambient temperature recorded for the experiment was 305.8 K and the mean ambient velocity of air was recorded as 2.03 m/s. The exergy efficiency varied from 1.79 to 2.47% for average solar radiation of 750 W/m2. The Therefore, performance is acceptable and recommended to use as affordable way of cooking using solar energy.
一种家用太阳能抛物面炊具的火用分析
本文对抛物面式太阳能炊具进行了试验研究。实验是用3升水作为烹饪液进行的。商用抛物面碟式家用聚光器(SK14)被用来聚焦太阳辐射,而一个变黑的烹饪容器被用作接收器。实验记录的平均环境温度为305.8 K,平均环境空气速度为2.03 m/s。当平均太阳辐射为750 W/m2时,其㶲效率为1.79% ~ 2.47%。因此,性能是可以接受的,建议使用经济实惠的方式使用太阳能烹饪。
