Passive downdraught evaporative cooling. 1, Concept and precedents

This is the first of a series of four papers that describe a 3-year EU-funded research project into the application of passive downdraught evaporative cooling to non- domestic buildings. In this paper various evaporative cooling techniques are reviewed. By spraying fine drop lets of water at the top...
