| Abstract | This study presents the work done to investigate the performance of hybrid
photovoltaic/thermal air heating system in six different modes of operation, namely: (a)
Natural circulation, single-pass, no cover, (b) Natural circulation, unidirectional double-pass,
(c) Forced circulation, single-pass, with stagnant air in the lower passage, (d) Forced
circulation, single-pass, with stagnant air in the passage, (e) Forced circulation, unidirectional
single-pass and (t) Forced circulation, reverse directional double-pass.
An experimental set-up was fabricated using both rectangular and circular cells and tests were
conducted at these modes. The total cell area used was 2.288 1112. Altogether twenty
experiments were done and the observation of results was presented in terms of outlet air
temperature, temperature of photovoltaic cells, absorber plate and the various efficiencies
(thermal, electrical and total).
The test results indicate that Mode V, which is the unidirectional double-pass system with
forced air circulation, gave greatest efficiencies compared to other modes: 50% and 5.09%,
respectively for thermal and electrical efficiencies.
The experimental results were compared by model and simulation results for these modes. The
comparison of temperature and efficiencies was found to be good.
The applicability of this system for actual use for drying and electricity generation has been
studied and the modes most suitable for these types of applications proposed. |
