A room air conditioner is a machine which has all its parts confined within a box. They are the smallest type of air conditioners, making them popular because of their manageability, while most of them are affordable and are of optimum functionality.
This air conditioner usually works with the Freon system, which involves using a refrigerant that sucks up heat from the air within a room. Generally, room air conditioners absorb the heat within a room, replacing it with cool air while simultaneously expelling hot air from an outlet, usually a window or an air vent. A few other important components make this process possible, some of which are a compressor and an evaporator.
There are various types of room air conditioners. While portable and window air conditioners are widely used, window air conditioner is particularly favored among the two due to some added benefits it possesses. Quite a number of factors are to be considered when choosing a room air conditioner for yourself. Location, along with machine size are crucial factors to look at. Noise level is another thing to be considered, as many air conditioners are noisy when powered on. The British Thermal Unit and energy efficiency ratio of the air conditioner, should be noted, as they tell you the rate at which the air conditioner cools the room.
