Research project

Transpired solar collectors (TSCs) are simple façade-integrated solar air-heating systems that can collect heat resulting from solar radiation. TSCs are typically able to deliver air 10-15°C warmer than ambient external temperature. This warm air can either be ducted directly into buildings or be used as preheat for HVAC (heating, ventilation, air conditioning) systems. An opportunity exists to optimise and enhance the thermal efficiency of these almost maintenance-free systems in order to be used in both residential and industrial buildings.

The aim of the research is to develop an accurate numerical model of the complex fluid flows and heat transfer mechanisms in TSCs and to use this model to improve critical aspects of the systems’ performance and efficiency. The model relies on computational fluid dynamic (CFD) based approaches. Then the model will be used to investigate parametric studies on the variables which are believed to be effective on the thermal performance of the system including suction ration, wind angle, sun position, radiation intensity, etc.
