<p>Dear All</p>
<p>I'm going to control a cooling system such as my building temperature does not rise above 25 C . In case of using single speed fan , I can use a thermostat to sense temperature and turn on the fan whenever it is above 25 C . using variable speed fan results
in lower energy consumption if it is controlled properly. If I use a variable speed fan, could you explain me how it should be controlled? when it should work at part-load and when itworks at full-load and how I can implement it in TRNSYS?</p>
<p>Thank you </p>
