Check out SenseAir Co2 sensors as well.
I did turn off the fresh air intake from the dehumidifier today. I will see what it smells like, what the Co2 measures and what it feels like when I get home.
Why I prefer to use the...
Ok, So I did some testing.
Used my 6" insulated flex duct that is bringing in fresh air from my soffit connected it to the Fantech FB6 filter-box with a MERV 13 filter in it.
Cold day and windy...
I haven't received my filterbox yet but I did do a test by unhooking the dryer duct from the 4" vent and turned on my 140cfm Broan bathroom fan (which actually pulls around 100-105cfm measured)...
another good one.
PDF file from Building Science web site about ventilation in all types of climates.
They also say not to ventilate more than 7.5cfm per 100sq.ft in a hot humid climate. According to ASHRAE 62.2 2010
I had messed that one up..
(7.5x4)+(1800 x 0.01)= 30+18= 48 cfm
48cfm/65cfm= 0.738 rounded up to .74 that is 74%
48cfm/75cfm= 0.64 that is 64%
So if 48 cfm is supposed to be delivered constantly to meet ASHRAE than a...
The blending of the fresh air with inside air can be accomplished by drilling a hole in the Fantech FB6 filter and install another duct that would pull inside air through it via a inline fan.
Its pretty tight dont know about submarine tight. Hehe..... I guess I will try it and if it doesnt work out at all I can get an inline fan to suck that air inside 67W still beats 150W. :-)
Just read this article about balancing an exhaust only ventilation system with a "passive" fresh air intake.
I was thinking...
Did not buy a ozone generator. I thought I bought the best filter out there, it was installed when house was built. Found out after the fact that introduces ozone.. :-/ it's turned off right...
Thank you for that information I will order a test kit.
Any kit in particular you would recommend?
Oh and here is a link that study and others http://ihcp.jrc.ec.europa.eu/our_activities/health-env/indoor_air_quality/eca/eca-report-no-11
Has anyone noticed that when using electronic air cleaners in a foam insulated home the smell of ozone? Does the Ozone concentration increase when these units are operated 24/7 in house that is...
interesting read on classification of indoor and out door air quality in europe.
See chart of classification of indoor Co2 levels..
Fan uses 150W (tested with kill a watt EZ). Seems to be accurate... tested measuring CFL light at 12W and hairdryer at 1875W.
This is interesting.
Just for the record where is your house located?
On slab or crawlspace foundation?
How is it insulated?
Was everything caulked to seal it up from base-plate to between all...
The damper and thermostat seems to be pulling around 18W
I will get this watt meter replaced as I just found out it's not reliable for any items pulling less than 120W. :-(
The watts are measured with the Dehumidifiers power chord connected to a watt-meter I bought at Lowes. Tested with fan only running and damper open 182W usage when adding dehumidifier 800w usage. I...
I have come to this realization.
The fresh air intake on the dehumidifer is a 6" flex duct about 8' long with a motorized damper that opens when thermostat says to ventilate. I realize now that I...
I wanted to share my whole experience with this new house build.
1. I got the HVAC system and foam installation engineered by Energywise Structures for my 1800sq/ft house. They provided...
yes I took the advice to use a dehumidifer with fresh air intake to make my house more comfortable to live in. Before I had no fresh air intake and VOC's would have a very strong smell...
I got the dehumidifier installed with the fresh air intake according to Ex: B on page 5 in this link. http://www.forwardthinking.honeywell.com/related_links/dehumidification/dh90/install/69_2407.pdf...
