Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Help Support :

I would love to get my hands on that Pepsi bottle machine. I wonder what size it dispensed, 10 or 12oz.? Or possibly 6.5oz, I highly doubt it though.
 
*LOL* smoking in the laundromant? The dryers will suck that smoke and odor right through one's clean unmentioanables.

I never understood why one needs an exhaust fan sucking more air out of the laundromat. The dryers do that already. What one needs is an unresticted place for air to enter!

Neat pics!
 
Don't forget about the Gabberts Store at 800 Nicollet Avenue in Downtown Minneapolis, taken November 29, 1957.

A 51 story office tower now stands in its place!

Exahust Fan

You've not been in a laundromat on a hot and humid summer's day have you?

Air conditioning isn't an option (would be foolish with all those dryers going), so one has to do something.

Local laundromat leaves the back service door open, and front door as well, along with the fan going, and still wouldn't go there on a hot day.

Problem is the same really for all sorts of commercial laundries, probably worse where ironers and other other heat generating equipment, and or steam boilers are running as well.

If one examines photographs of laundries, old and new, you will see fans (or very large windows). In the days before electricity and or fans, it was HELL to work in a laundry during warm months of the year. And since labour protection laws, and unions weren't that strong, you either put up with it or quit.
 
Not a Laundromat - but what are these machines?

The photo of a basement shot of a newly constructed home in Edina, MN has Norge Timelines in it...the dryer is a newer model than the washer. That home has some heavy duty plumbing and heating.
 
Dryer intake question.

The highest efficiency gas furnaces these days have 2 flue pipes. One for exhaust, and one for intake. This way, they aren't using the air they have already heated for combustion and exhaust. Many installers only route the exhaust out of the building, and leave the intake inside. This lowers the efficiency of the heating system considerably. Also, these types of furnaces can be installed in small closets without ventilation and louvered doors. The louvers on the doors are there so a less efficient furnace can suck enough air for combustion. If the furnace gets its air from the outside, it no longer needs to be in a well-ventilated closet. Failing to connect the intake pipe to the outside when the furnace is installed in a poorly ventilated space can cause there to be insufficient oxygen for proper combustion, leading to carbon monoxide.

The reason for this ramble is: has anyone ever marketed a dryer which takes its intake air from outside? It would seem to make sense, that way the dryer isn't blowing the heated or cooled air out of a building. The only downside I can think of would be the possible need for a filter to get rid of dust from the intake air. Of course, if the indoor air in our buildings is more polluted than the outside air, it may be an improvement, even lacking a filter.

Just some disorganized thoughts,

It is zero degrees here.....

Not sure, but think that it does.

Every dryer owner's manual I've read states that drying time can be affected by the temperature of incoming air. Which when you think about it does make sense, since incoming cold air must be heated longer in order to generate temperatures needed to satisfy the thermostat/heat laundry.

One does suppose the change in efficency would probably be small on a high powered gas or 220v dryer, versus say small 110v appliances, which struggle with puny heating anyway.

Humidity vs. temperature.

Cold air is capable of holding less moisture than warm air. I think a greater potential problem might be when the weather is warm and humid (Savannah, GA anyone?).

I think if cold, and relatively dry air, is heated so it could hold more moisture, it could perform very well in a dryer.

Your thoughts?
