EXTRACTOR FAN FREEFree early morning cooling An often overlooked additional advantage of extractor fans is theirĪbility to provide ‘free’ early morning cooling.īy connecting a timeswitch to the extractor fan, cold early morning air Once the temperature exceeds this, theįan will start, removing the hot air. EXTRACTOR FAN INSTALLControlling the extractor fan The simplest way to control the extractor fan is to install a thermostat Installed at the cooler North end of the building, with the extract fans at the To create air movement through the roof space the air inlets should be To calculate their size in square feet, multiply the airflow of theĪrea of air inlets (sq.ft.) = airflow x 0.0033 If the roof is dark: Airflow of extractor fan (CFM) = Airflow ofĮxtractor fan (CFM) x 1.15 Air inlets To allow fresh cooler air to enter the roof space, air inlets must be If the outside surface of the roof is dark coloured (darkĬolours absorb the suns heat very efficiently) add 15%:Īirflow of extractor fan (CFM) = length of roof (ft.) x width of roof What size fan is needed? To calculate the size of extractor fan, work out the area of the roofĪnd multiply by 0.7. The most effective way to lower the temperature inside buildings is toįit extractor fans to expel the superheated air from the roof space. The sun heats theĪir in the roof space to over 60C (140F) in turn this superheated air heatsīoth the structure of the building and the cooler air below. In commercialīuildings such as factories and workshops, the warm air generated by machineryĪnd workers rises into the roof space where it is trapped.
