Need ventilation solutions for my condo. Ceiling fans?(20 posts)

Need ventilation solutions for my condo. Ceiling fans?Kristin
Aug 29, 2003 10:19 AM
Someone said something about the fact that ceiling fans don't actually help with circulation. At the time, I was about ready to have 2 fans installed. I need some kinda solution.

Here's my deal. I own a 2nd floor internal unit. In the winter I barely need to use the heat at all. Since April, I've needed to run the AC 24/7. I have two west facing windows in my place. One in the bedroom and one sliding door in the living room. The two rooms are separated by a hallway. Currently, I no air flows through to condo from the outside. Its pretty stifling, and even on a cool night with the windows open, I must run the AC to keep the temps below 85 degrees. What can I do to create and air exchange through my place from the windows?

Here's my floorplan incase that helps:

I had luck with a window fan this year. My AC was making too much noise and the window fan did the trick nicely. I really did not even miss the AC. Saved on energy costs as well!!!

Found that it made a big difference in a room where even opening a patio door didn't help.

To move air through, it seems like you'll need to open your slider and your bedroom window, and have a fan at one or the other. You can have a window fan blowing into your bedroom, with the benefit that it'll blow over you (& vent out the slider). The down side could be some some noise. For less direct air flw in the bedroom you can have a regular fan blowing out the slider, to quietly draw cool air in your bedroom window. Belt and suspenders you can have fans in both places - one pushing the other pulling

People put fans facing inward when they want the inside cooled down or ceiling fans for that matter.

What you need to do, and I'm not the designer, is find a fan or fan unit and place it as high as possible and facing out of the house.

Then, when you turn it on, it takes the warmest air inthe house and send it out, creating a vacuum in the house, which then pulls cooler air from outside the house.

You don't even need windows open because the air that will fill the vacuum can seep in through the cracks under the doors, etc.

Swirling the warm air around creates a windchill, but kicking out the warmest air, lets fresh cooler air into the house. Sounds good to me.
you have no cross ventilation.dr hoo

I think your best bet would be to put a screen door on your entry, that way you can get some cross flow going. That, plus a good air moving fan, should allow you a relatively rapid air exchange.

But given your lay out, this might not do the trick in terms of comfort level. You live in a brick oven.
No no...that would be badKristin

Its like a hundred degrees in the hallway. I want to keep that air out. Also, the association would not like it much if I installed a screen door. Big no no. You are correct, I live in an oven. I can thaw frozen steaks on the counter at an alarming rate.
ah, thought the door might lead to outside.dr hoo
Aug 29, 2003 11:17 AM
there is not a lot you can do with airflow. With 2-3 fans you can get something moving through at a good rate, assuming the wind is not blowing directly into your windows. Still, it will not be very effective. I think you best bet is just to go for the AC. Baring that, stick an infan in one room and an outfan in the other. That should help a bit, most days.

And of course close your blinds/curtains in the afternoons.

I don't see where the problem is. Deal with the heat, girl. Sounds like anyplace else would be an obstruction to enjoying more cow.

OK ... sorry I don't have anything constructive to say. Enjoy the weekend.

Pretty cool. They mount inside your attic door or you can punch a hole in the ceiling too. Your attic must have vents in the awnings or in the roof in order to exhaust the air that the fan draws from the living area of the house/condo.
LOL. When was the last time you saw a condo w/and attic?Kristin
Aug 29, 2003 11:43 AM
That's funny. I supose I could punch a hole thru my living room ceiling into my upstairs neighbors ceiling, but he might not like that very much. I think I might have some problems with the resale value if I do that as well.
Sounds like it would do wonders for your re-sale value. (nm)czardonic

Kristin it looks as if a window fan is your best optionLive Steam
Aug 29, 2003 12:21 PM
You are limited by the modification you can make to the structure, etc. You will have to experiment with placement and air flow direction to get the optimal results. A ceiling fan isn't a bad idea to help pull the warm air away from the ceiling and exhaust it out with the window fan.
Thanks to everyone for the useful repliesKristin

I think I may look into getting a fan that I can mount high in my bedroom window to pull air out and a floor fan in my living room to pull air in. More stuff. Ugh. Its fun trying to squeeze everything into a 700 sf space.

Firstly, you wrote that on a cool night with the windows open you have to run the AC to keep temps below 85. This is a big NO-NO! If you run AC, keep windows closed.

Secondly, you may want to make sure your AC is working properly. You say you run the AC 24/7. If that's the case, it should be near freezing in there. Are you sure it ain't broke?

FWIW I need to run AC pretty much all the time. The coolest it gets outside at night is about 76. Add the humidity of summer and it would be pretty painful to have the AC off and the windows open, regardless of how much airflow was coming in.
Haahaaaa. I guess I should have stated the obviousKristin

Central Air. My furnace & AC are less than 1 year old and its a very nice setup. The blower doesn't actually run 24/7, only when the temp rises above the programmed figure. I basically meant that if I switch the thrermostate from "cool" to "off," within 1 hour the tempurature would rise to 95 degrees. (That's in the summer, of course. In the winter it stays at around 73 degrees, except on the coldest days.) Problem is, gas is included in my assessment. Electric is not. And I don't really run the air with my windows open. I was using that as an example.
Well OK then...Fez

West views are probably the worst as far as getting hot in the summer. Chicago heatwaves don't help.

FWIW, I have a south view. Definitely not as hot as a west view in the summertime. Still, I pretty much have accepted that I run the AC whenever I am home. I have good air circulation, but it would never be comfortable enough not to run the AC.

I have my AC set at 73-74 in the summer. Any higher and it won't be comfortable inside. I can't rely on the windows/fan until the outside temp drops below 68. That's still a few weeks away.

Fans and good air circ definitely help, but don't expect it to replace the AC this time of year.
