Is There Such A Thing As An Indoor Air Conditioner That Needs No Ventilation?
We have crank out windows and cannot figure out a way to install a window air conditioning unit. Is there such a thing as an indoor air conditioner that needs no ventilation?

There are refrigerated air conditioners made to fit casement windows (the crank kind) but they are not easy to find.
any refrigerated a/c needs drainage to the outside of the house. Your home refrigerator is like an a/c but the amount of condensate (water) produced is so small that it drains into a pan at the bottom of the refrigerator and evaporates into the room air. If you lived in a swamp then it might need a drain.
There is one unit that only needs a fourinch wide opening…it is made by mitsubisi and is expensive and requires professional installation. By expensive I mean over $1000 for the unit plus installation. If you live in a very dry climate there are portable evaporative coolers but they have to be emptied daily and there is the possibility of overflow.
If you own the house you might consider replacing one window. That is expensive too…in the $400 range depending upon the size but less total than the misubisi unit
ask dealers if they can order a unit made for casement windows. I used to have one but that was over 25 years ago.
No…no such thing. You can get some units where a small hose fits out of a window. These are small “room” units, however and I don’t know how efficient they are or how well they work. With a/c, not only are you cooling the air, but you are also extracting humidity from it. As long as that is happening that humid air and condensation need somwhere to go. If you live in a very dry, desert-type enviornment (utah, nevada, etc) you can buy a portable swamp cooler (aka evaporative cooler) and you don’t need to exhause those…but you do need to fill them with water. If you live in an area with more than 40% relative humidity, however, a swamp cooler won’t do anything but make things more humid.
Not to my knowledge. Today’s ACs produce a temperature differential in two closed loops. One loop is cold, the other is hot. The AC is placed outside so that the heat can be vented into the atmosphere, and the cold loop is vented into the ductwork in your home.
