How Do Air Conditioners Work?

Many individuals use air conditioners throughout their lives without ever understanding how these appliances work. The cooling process that goes on inside your A/C unit is actually very similar to the one in your refrigerator. Air conditioners have three main parts: a compressor, condenser, and evaporator. A cooling agent such as freon runs through these three components and changes from a liquid to a gas and back again as it completes its circuit. Through changes in pressure, the coolant runs hot as it passes through the section of the air conditioner that vents air outside, and then runs cool when it gets to the section of the appliance that blows air into your home.

Types of Air Conditioning Units

Unless you have central A/C in your home (which is provided by a large unit located outside the house), you'll have to choose between options like a window, wall, or portable air conditioner. Window-mount units sit within the jamb and are held in place by partially closing the window until it sits flush with the top of the air conditioner. These units bring in air from outside to cool. They are equipped with two fans so that one can vent hot air back outside while the other blows cool air into your room. Wall air conditioners work on the same general principle, except they fit into a sleeve cut out from your wall rather than sitting in a window.

Portable air conditioners are slightly different in that they can be installed anywhere in your home--even if you don't have a window the unit can fit in or a wall sleeve. These units sit in your room and use air that's already inside your home. They then use a fan to blow cool air into the room and are equipped with an exhaust hose that you can direct out the window to allow the hot air to blow outside.

Choosing the Best Unit for Your Room

You'll want to choose your air conditioner based on the size of the room it needs to cool. The power of these units is listed in British Thermal Units (BTUs), and a higher BTU rating generally means that the air conditioner can cool a larger room more effectively. Typical BTU levels for room air conditioners range from 5,000 up to 25,000, and you'll usually find a recommended room size listed to coincide with the amount of power offered by a unit you're considering.

The welcome relief of air conditioning can make summer a much more enjoyable season in your home. Browse our selection of room air conditioners at drugstore.com today.
