Ventilation in Humid Climates

Good video Bryan

[@dantripps9695]

Thank you for the video. I am living in Portugal. I have a very old apartment. No tight seal… wood windows on stone and plaster window sills. The humidity levels outside in the winter here are around 80-90%, and temps are in the 40s at night and the 60s in the day. There is mold growing on my cloths and walls. Can I have a Zoom call with you? I need to know if a dehumidifier would be helpful (remember, no tight seal in this place), or if a portable convection heater would be good… or both.

We use a ventalation Hoeywell dehumidifier with a honeywell 8000 tstat and a two stage zoned furnace at the company Im at in SC. We alsonhave high humidity and dew point temps

The company I work for does a lot of new construction & most of the builders are Energy Star which requires fresh air. We vent the fresh air pipe into the return (before) now most of our installs are into a coffin box. The fresh air essentially gets conditioned before it goes into the home. We are using a Honeywell controller which requires the tech to input home size, amount of bedrooms & com desired. We were wiring them up to only let in fresh air if the system had a call (heating/cooling). Then Energy Star said no that's not correct it needs to bring in fresh air even if theirs not a demand. I'm sure you can figure what happened then! (Tampa Bay area) What are your thoughts on this? We basically now just wait until 30 days after homeowner is in home & wire it to only bring in fresh air if theirs a heating/cooling call.

So, how about my condo here in Florida 14th floor. If I am going to be away for 90 days, should I leave my window cracked?

Is it possible to be cold and humid at the same time?

[@TheYellowAznBoiZ]

I'm not that smart with the topic but the basic is yes, but colder air hold less moisture than hot air due to it being more compact or whatever, so a 100% humid cold day wont feel as bad as a 100% humid hot day since cold air hold less

Very pertinent information. I sure hope everybody appreciates the amount of time you put into trial and error, research and true testing. I sure do. Keep up the great work!

You can be at 100% humidity at every temperature as a graph of dew point. A given volume holds less and less H2O at 100% relative humidity as you drop the temperature. Wind chill effect on skin can depend on the individual. Pretty much has Zee Dic said.

it sure is in Portland OR. 65 degrees seems to be the divide and 55 degrees feels like a dry 45 degrees. Just imagine getting out of the shower in a 55 degree room.

It's 6:am and my home is 69 degrees inside right now its going to be 107 where in live in Southern California today and it was 106 yesterday and never did I turn on my AC not even for a minute. Our humidity outside is 17% and my Bonair 5900 evaporative cooler is blowing like an AC. As long as some fool doesn't spark a brush fire we won't need to use our AC. Thats a 36 degree temperature swing without useing AC.

Why haven’t someone come up with pulsing the air handler’s heat strips to allow long run times to reduce humidity in the home? The ultimate whole home dehumidifying solution, and no extra unit needed.

Bryant Evolution extreme systems do have this ability but that wont bring in fresh air in a controlled way like a dehumidifier will.

[@adb99999999999]

@@synackack evolution extreme and infinity 26 (and 19, for that matter) will ramp down the compressor for better dehumidification but they won’t run electric heat for dehumidification purposes
