In the hopes of ventilating nasty odors and airborne contaminants, I recently installed the Bionaire BW2300 in one of my kitchen windows. This is the only one I have installed in my home at the moment. I leave it on 24/7 with the AC running at 82 degrees. Outside temperatures during the day hover around the 90s. So far the AC turns on and off intermittently for 5 - 10 minutes every half hour. (Trying to reduce my energy bills as well. Last month was $190.)
This morning I discovered that -- in combination with the exhaust fan -- the overall room temperature falls 2 degrees if I place a circulating fan between the short corridor that separates my living room and kitchen. I positioned it in a way that air is being pushed toward the exhaust fan.
Now my idea is to place between 1 - 3 Vornado 270s in the small corridor as well as the main hallway. The main hallway separates the living room from the three bedrooms. So it's basically t-shaped with the central AC located at the point where the "two lines of the T" intersect and form right angles.
I don't know what I'm doing, but based on my experiences so far I'm guessing it'd be beneficial to position each of these fans so that air travels from the hallway, into the living room, and then through the kitchen to the exhaust fan. That's from one end of my home (vicinity of the central AC) to the other (kitchen/patio).
So what do you think about my idea of using multiple fans to draw and force air from one end of my home to the other end? My goal is to use the exhaust fan to vent excess heat and to improve air quality.
Additional information: I have only one exhaust fan for security reasons, so I can't position a window intake/exhaust fan anywhere else. Circulating fans are fine. In addition, my family has seen a noticeable disruption in the air flow when the front door is opened (opposite end of home). The rotation of the exhaust fan's blades slows down momentarily.
