Do you suppose some people just never think about where all that air has to go?
My dryer's not working very well. Well m'am if you had the vent cap replaced or actually installed and the vent pipe cleaned or replaced it might work a little better.

Never knock on Death's door. Ring the bell and run, he hates that.

WOW !!!!
That was a fire waiting to happen.
I get a kick out of owners reactions when we do appliance disconnects and they get to see a mess just like this.
Here's your sign...
....and you know there are THOUSANDS out there just like it!
I thought they ALL looked like that. Most people don't have a clue...
Changed one like that this summer. They were complaining the a/c wasn't cooling like it used to. 100% of the dryer heat/humidity was staying in the house, and they were washing 4 loads a day!
Dryers are a huge drag on your AC system. They pull in conditioned air and blow it out the vent. I bet 50-60 cfm at least!
Probably worse than conventional fireplaces.
heh, and the vent is now well insulated too... too well...
Maybe it's time for more manufacturers to make ventless heat pump clothes dryers.
And I guess there's a condensing unit underneath just so you can say it's a heat pump.
LG already makes one that uses a heat pump, and it does take a while to start up on a cold day. On average, it uses about half the energy of a regular dryer during one drying cycle. Only problem is that it uses R22 (I think, haven't really checked) and already operates at high pressures so once R22 is phased out, they'll have to find a HFC that still operates at reasonable pressures. (Just got an idea: why not pull a partial vacuum (25inHg should be attainable with a simple pump) first so water boils at a lower temperature, thereby reducing the refrigerant temperatures and pressures?)I actually have a home-brew one of these going here. Works quite well, but it takes quite awhile for it to work. BUT, the energy savings is tremendous.
BTW, what refrigerant are you using for your homemade unit?
Just using R-22... basically I was given a bunch of dead dehumidifiers and decided there had to be a use for them, esp. after seeing the condensing-type clothes dryers in the UK which use water for cooling/condensing. An old GE dryer, some redoing of the copper, and some ducting (made it a sealed system) and it works. I'm sure it's nowhere near the best it could be, but the clothes do get just as dry as the Bosch condensing machines I used in the UK.
Dumb question, but what is "low grain refrigerant"? I've noticed all of the dehumidifiers used by the dry-out companies claim to use this, whatever it may be. Links on the 'net just show me equipment which use it, but doesn't go into any detail on what it really is.
What are the operating pressures when fully warmed up? The LG unit I talked about has design high side pressure in excess of 500PSI. (I think it listed 630PSI but I'm not sure.) I'm pretty sure it can actually reach that pressure since it often trips on high pressure (thereby starting an automatic coil clean cycle) when operating during a hot summer.
Once R22 gets phased out, I have no idea what they're going to use. (R410a will probably operate at pressures in excess of 1000PSI in a clothes dryer so it's not a practical option. But if a simple vacuum pump first pulls 28" of vacuum so water boils at a lower temperature...)
I got a jennifer lopez dryer
The way we build has a greater impact on our comfort, energy consumption and IAQ than any HVAC system we install.
