A systematic review on parametric dependencies of transpired solar collector performance

Zero or low-carbon buildings can be achieved through novel technology solutions and integrating renewable energy into the buildings. One method of reducing the fossil fuel dependency of buildings and limiting greenhouse gas emissions is integrating the solar thermal system into the built environment. Recently, transpired solar collector has been identified as 1 of the most efficient solar thermal conversion technologies where a very high efficiency can be achieved. The proposed review paper investigates the performance of transpired solar collectors (TSCs) and discusses the relevant case studies in this context. This paper introduces the background and concept of TSCs. It mainly focuses on the study of parametric dependency of the performance of TSCs. The paper also investigates various mathematical models, experimental study, and numerical simulations particularly CFD used for TSC performance analysis. This proposed paper concluded that wind speed and airflow rate are the most dominant factor in TSC performance but solar irradiation, hole diameter, hole geometry, and pitch size have limited effect on TSC performance; also, profile with longer pitch tends to lower the collector efficiency and heat transfer coefficient. However, profile with shorter pitch tends to reduce the wind effect.
