Dryers Use Dirty Air From Inside the Cabinet and Floor Around the Machine

Paulo,

Most dyers can be retrofitted now ,even old ones.The 4" cabinet knockouts are a perfect  fit.Most have/had these.

My F&P SmartLoad runs the cooldown until the exhaust temp is 95°F.  It wouldn't shut off at an ambient of 110°F unless there's a failsafe time-out.

yet odd, in manufactured homes(mobile homes), behind the dryer is an air intake vent to allow the exchange of air, at least in the general area, without sacrificing that much conditioned air...these homes are sealed tighter than most wood build homes.....this vent is needed for other vented items like bathroom vents and range hood vents....even opening and closing a main door can cause a sort of vacuum to the interior...

I don't run the dryer in the main bathroom when heat or A/C is on, only on days where we have the windows open......and when using the units in the basement, I crack a window open, and close the door to the laundry room.....

one dryer is bad enough, but running 3 or 4 at a time is a substantial amount of conditioned air that is being exchanged....

Good point on the F&P. Thermistor circuit board controlled with no adjustments???How would it work in alabama on someones back porch on dog days?

That smartload dryer has a few drying options to include manually set timing.That's what I would use when it's 100 degrees .

Martin ,

You are 100% correct.That is considered make up air required for that mobile home's application per the federal government--Yes thats right,The feds .

I guess a clothesline would solve everything

Outside temps in the summer  reach 110+  all the time, but in my non-air conditioned garage it never gets more than mid 90's. The garage is insulated and sheet-rocked like the house. The garage door is thick and insulated and seals very well. Still if I could get the dryer to draw air from the garage it would be economical. I suppose if I closed the laundry room door a very small percentage of air might be pulled from outside through the laundry room vent fan...probably not enough to make any difference. I have a feeling that installing a vent in the door that goes to the garage would be taboo. By law it has to be a "fire door".

Palm springs with it's 70 degree average temperature would make me care less about a dryer.Hot days??Why not a clothes line .

Duke:

I understand that part, retrofitting the dryers. Seems easy for electric dryers (one could connect the external air duct straight into the heater).

I am wondering if just leaving the duct open to the cabinet in case of a gas dryer wouldn't cause problems like outside air coming into the home when not desired. I was thinking of the similar case of furnaces where the make up air comes straight into the burner and leaves thru the exhaust, and there is no exchange with the home air.

I'm also completely ignorant if one needs dampers or extra equipment in the case. Which is why I thought it would be helpful if the dryer manufacturers just offered the product ready to connect to two vents and we wouldn't have to worry about it.
