How to Choose the Best Portable Air Conditioner
Choosing the best portable air conditioner for your home or office can be a fairly difficult task if you don’t know what you’re looking for. The problem is that there are two general types of air conditioners available, and one type has a couple different styles available. Each style has its pros and cons, and it’s best to understand them before you start shopping around.
The first, and generally the cheapest, option in portable air conditioning is the evaporating cooler. This type of air conditioner operates on the principal of pushing hot air through a water-logged medium will cause evaporation and reduce the ambient air temperature. These units require no ventilation, but they do incorporate a water basin that needs to be refilled on a regular basis. You also have to remember to clean it, as it will begin to build up a musty odor if you don’t. These air conditioners are best used in dry areas, where evaporation would be most efficient, and areas where intentionally increasing the humidity in a room would not be an issue.
The second option is a cool that uses a refrigerant rather than evaporation. These units do require ventilation because they use an exhaust tube to move hot air outside of the area that needs to be cooled. Dual-hosed units use both an exhaust tube, and an intake tube, while single-hosed units use only an exhaust tube. The reason for the intake tube on a dual-hosed unit is to pull in additional air from the outdoors, or elsewhere in the building to evenly distribute air pressure. With single-hosed units, you might end up causing a difference in pressure which allows hot air from higher pressure areas to be pulled into the area being cooled. Single-hose air conditioners are best used in small rooms, but if you have a medium sized room (over 500 sq. ft.) then it’s best to go with a dual-hose unit.
These are you two basic options in portable air conditioners. If you have no access to windows, or an area for the hot air exhaust, then the evaporative cooler is the way to gp
