Mathematical modeling and thermal performance analysis of unglazed transpired solar collectors

In antiquity, people already knew the principles of solar architecture, designing their houses to the south to take advantage of the sun in all seasons. Today, solar architecture is undergoing a true revolution because of the development, among other things, of special facades involved in the processes of heating, ventilation, thermal isolation, shading, electricity generation and lighting of homes: these are called “solar facades”. This paper aims to review the remarkable developments that have occurred during the first decade of this century in this field.

The application of air layers in building envelopes: A review

A prototype photovoltaic/thermal system integrated with transpired collector

Utilisation of solar radiation to heat air for various purposes, e.g. ventilation, pre heat, process air heat and their applications has attracted more and more interests. Wide range of applications adapted for different climates and in different building types ranging from houses to large industrial buildings. Recently in many European countries, USA and Canada this concept developed rapidly. Transpired solar collectors (TSCs) have proven reliable for various applications, e.g. heating spaces, providing warm ventilation air, supplying domestic hot water in summer, etc.Present paper consists of introduction to various types of TSCs, working principle, research literature for performance and modelling. Further various models have also been discussed and compared. The literature has shown that the most critical factors affecting TSC efficiency are wind velocity, flow rate, porosity, absorptivity and porosity.
