How Does Air Conditioning Work?

Have you ever wondered how window air conditioning works? Heat is usually easier to explain, because we have all seen how fire can be created with friction to produce heat. However, cool air is mostly a function of the season. If you live in an area that produces hot and humid summers, it is probably very important to you to understand how window air conditioning works so that you can effectively keep your home comfortably cool during those dog days of summer.
Window air conditioning is specifically designed to cool an individual room or area of a home or office. The bulk of the unit is outside the home and the rest of it sits in the frame of the window. It takes up minimal room space and the warm air from the room is directly vented to the exterior of the house. The room air moves or is drawn over cooling refrigerant coils that are located in the window air conditioning unit. The compressor, with fins that make it look like one in an automobile, sends a refrigerant through the coils and a transfer of heat occurs. The air is cooled and the heat is passed out of the home through the vents.
As the room air moves across the refrigerator coils of the window air conditioning unit, humidity is also removed from the air. This humidity is used to help cool the coils, which makes the unit more energy efficient. The cooled and drier air is sent back into the room by the fan in the window air conditioning unit, which may be louvered or oscillating, and the room begins to cool down. As the warm room air is traded for the cooled air, the entire room soon reaches the desired temperature.
Because the window air conditioning unit is designed to both dehumidify and cool a room at the same time, it makes a big difference to have the correctly sized unit for the room. Some people think it will help keep more of the house cool if they put a bigger unit in a small room, but they are actually defeating the purpose of the window air conditioning unit because the air will cool too quickly and won’t have time to be dehumidified. You can look on the Internet for charts that show you the BTU size for different rooms, so you can measure and know what you are looking for before you go shopping.
Shopping for your window air conditioning unit with the correct size in mind will make things much easier for you. You will know exactly where to begin and can then concentrate on the different options and features that the correctly sized models offer. Cost will depend on both size and features, but window air conditioning units are relatively low-cost appliances, and they are designed to be energy saving so that future costs of operation are also low. Understanding how the window air conditioning works will help you know what you need when you are in the market for an appliance to keep your home cool.
