Air Conditioners are the best friends in summers. With temperatures soaring high, there cannot be anything better than Air Conditioners. Some time back air conditioners came with the sole purpose ? to beat the heat. That means, they could be used only in summers to beat the scorching heat, but, things have changed today. Today's air-conditioners come with many-fold things ? they can change their temperatures automatically with the change in outside temperatures, they can also be used in winters with the temperature in the room so maintained that one feels at ease; even in rainy season humidity can be controlled in rooms with these air ? conditioners.

Different companies have given different names to these air conditioners ? some call them intello cool; some call them bio sleep and so on. Whatever is the sense of these air conditioners, they are not just an added assortment in the rooms and they are a part of life. One can say ? the best today's generation can have in the name of world-class comforts.

Basically, air ? conditioners come in two forms ? Walled units and Split form. Walled or Unitary systems, are fitted across the windows of the room whose controls are interior. These can be fitted in homes where each room can have a separate unit. In Spilt form or PTAC form, there are two units. The Evaporative unit in this kind of AC is outside the room and the condensing unit is inside the room ? a tube passes through them connecting the two units. (Some of the Spilt ACs is quite advanced in nature; they can heat the room in winters making these much better air conditioners than the walled units ? one of the main reasons why these are costlier than the window air conditioners).

Another class of air conditioners are the central units ? majorly used in hotels, restaurants, corporates and offices. In this type, majorly ducts are used to throw in the cooled air to keep the temperature cool or heated. Such kind of units can do both the functions ? keep the temperature low in summers and high in winters, keeping the dual purpose in full swing throughout the year.

In India, major companies which sell air conditioners include Samsung, LG, Voltas, Whirlpool, Electrolux, Armana, Sharp, General Electrical and so on?.
