Hvac School - For Techs, By Techs

If you're a fan of fans, this is the podcast for you! In this short podcast episode, Bryan shares how installing ceiling fans can be a smart HVAC design strategy (even though he wasn't a fan of fans!). Ceiling fans break the "don't blow air on people" rule we usually refer to in duct design, but they can solve quite a few basic comfort problems, especially in homes with lower loads than we've historically seen. They're great for creating high-velocity airstreams and mixing air. Low-load homes have systems with lower tonnages; they don't move as much air and could use a little bit of help from a ceiling fan. Air mixing is also poor in homes that have a greater distance between the air and the ceiling. Stratification of the air causes comfort problems due to temperature differences, and hot or cold surfaces can also contribute to these issues for similar reasons. Moisture and eventual growth are also concerns when we allow rooms to have those temperature differences (especially on the ceiling, as water vapor is
