Hey Ed, When Can We Blow Air on People?


Posted on:

In this edition of "Hey Ed", Ed discusses when, if at all, it is acceptable to blow air on people.

Hey Ed, with airflow, when can we blow air on people? How about never! One of the things that I’ve seen over the years, that I have always found very perplexing, is designs that people have done that intentionally blows air at people. That’s something that we simply don’t want to do. In residential applications, very rarely does the fan run continuously so if you had air blowing on you and then not air blowing on you, then air blowing on you and then not blowing on you, you’ll be very aware of that. If you were to look at the definition from Webster, comfort is defined as not being aware of your surroundings, if you have air intermittently blowing on you, would you be aware of that? I think you would and it goes against the definition of comfort so I am a big advocate of making sure that my systems never blow air on people and that’s the way I see it!
