Development of an Automatic Temperature Sensitive Air Control Device for Use with Passive Solar Gain Collectors

Summary

The energy benefits of advanced passive solar gain collectors such as Trombe Walls and conservatories are known to be improved where controlled air movement is provided. The aim of this research is to develop a low technology component which is simple, inexpensive and reliable and which is capable of sensing when energy benefits are obtainable and carry out action to secure those benefits. Control devices currently available are sophisticated, relatively expensive and have attendant installation and maintenance problems which could be solved by alternative self contained controls requiring no external power supply.

The project programme will commence with an appraisal of possible solutions to achieve the objectives mentioned above from which a prototype or prototypes will be developed, tested and rated on a “simulation” test apparatus. The final stage includes refining of the product to ensure its commercial and practical viability. During all stages, the performance can be compared with that of a local solar project utilising similar prototypes already developed by Waterloo Grille Company and the Essex County Council.
