Updated If you're looking for a portable air conditioners without a hose or window exhaust, then what you want is an evaporative air cooler (also called a swamp cooler or wet air cooler) which is basically a device that cools the air by evaporating water. Here are some good ones. These require water and with some units, you can even add in ice in order to cool the air down even faster. It works by sucking in the warm air in the room and cooling it down before blowing it back out. This results in a temperature drop.These air coolers won't cool your room down as much as regular air conditioners so if your home/room gets really hot, it's best to get a regular AC unit. The good thing about the air coolers is that it uses less electricity than ACs since they don't use energy hogging components like compressors. This means you get to save money because as you probably already know, traditional ACs can run the electricity bill up by a lot.There are a lot of evaporative air coolers to choose from varying in strength and coverage in terms of how much square feet of the room it will cool down, how much water it can hold, and other options like varies speeds.

These can be used indoor or outdoor and have caster wheels under them for easy portability.There are different models for different room sizes such as the one pictured below, made for medium to large sized rooms.I'd say if you're looking for something that will cool your room down more than a fan would but not take up so much energy or require you to stick part of the unit outside or run a hose outside, then an evaporative air cooler is the way to go.Learn more about evaporative air coolersManufacturer of pictured item: HoneywellWritten There are no ventless air conditioning units currently available, but there is an alternative called an Evaporative Air Cooler. These units cool the air by evaporating moisture through a material that is kept wet by being partially immersed in a tank of water within the unit.A fan blows air through the material, evaporating the moisture, and creating cold air that can reduces the temperature in the room. Because there is no refrigeration process, there is no exhaust air, and therefore, no vent is needed.

It also uses less power than an AC unit, so you could save some money on your electricity bill in the long run.This Honeywell model is pretty solid. Written So far as I know there is no such thing as a portable or room sized air conditioner that works without exhausting the heat removed from room air to some outside space, usually the great outdoors. There are larger units, commercial units, non portable, that can dump excess heat into water in a tank or other reservoir, with the water eventually being replaced with cold water via plumbing.So called swamp coolers or evaporation coolers are NOT AIR CONDITIONERS.BUT they do work rather well IF the humidity of the ambient air is LOW. They work GREAT in a low humidity desert environment for instance. But the savings on electricity are partially offset by the use of lots of clean fresh water, which can be pretty expensive in a desert environment.They are basically just about entirely worthless on a hot MUGGY high humidity day.I live in a place where hot days are usually also quite humid, and know maybe half a dozen people who have given evaporative coolers a try.

All of them took them back to the store for a refund.The reason they won’t work on a humid day is that water will not evaporate very well or quickly into air that is already loaded with moisture.DO NOT BUY A SWAMP COOLER EXPECTING IT TO WORK IN A HUMID CLIMATE.How do portable air conditioners work?air handling unit price list india Like normal air conditioners, portable air conditioners pull in warm air, cool it and circulate it back into the room. how do free standing ac units workUnlike normal air conditioners, all of the mechanical parts of a portable air conditioner operate inside the room.wall mount ac and heating unit What are the types of air conditioners? What are the different types of air conditioning units?

What are portable air conditioners? Using a traditional air conditioner requires installing the unit through a window, allowing the bulk of the unit to project outside. By contrast, the portable air conditioner is an enclosed unit. It sits on the floor of the room and houses the compressor and circuitry. Traditional air conditioners vent hot air outside of the room to provide cooling, whereas portable air conditioners use an exhaust hose attached to an exterior window. The exhaust hose creates negative pressure in the room, drawing warm air from surrounding rooms into the unit. The unit then cools the warm air and releases it directly into the room. Despite their portability, portable air conditioners are generally large and bulky. A typical unit weighs 50 to 80 pounds and must operate near a window for exhaust purposes. Many portable air conditioners feature wheels for easy repositioning. The hose of a unit is 5 to 7 feet long and requires plenty of space to prevent the blockage of airflow.

Portable air conditioners need a vent hose to pull air and cool it before it is channeled to the room. Certain brands and units are equipped with two vent ...
