Summer off-peak performance enhancement for rows of fixed solar thermal collectors using flat reflective surfaces

摘要: Abstract Collectors for building-scale solar thermal systems are generally fixed, so that energy capture is optimized over the course of a year, but not optimal on any given day. In particular, abundant sunlight available during summer mornings and late afternoons captured. Moreover, ancillary (pumps, piping, etc.) designed to operate at peak, meaning they underutilized majority time. this study, reflective surfaces used reflect morning onto fixed collectors. The orientation reflectors using simulation. simulation results corroborated by experimental data from 150 kWt system located roof University New Mexico’s Mechanical Engineering in Albuquerque, Mexico. study also considers economic performance benefits deriving combination with It found correctly predicts performance, reduction cost cooling approximately 20% can be obtained installation mirrors, without adding extra components system. Perhaps most important outcome booster mirrors extremely sensitive local climatic conditions constraints placed positioning reflectors, making it impossible generalize findings one particular location. Thus, computer essential designing optimizing reflectors.
