There are multiple types of air conditioning that people use to cool their homes or workplaces for their comfort. Today, there are two very popular kinds and types of air conditioning and these two are the central air conditioning and the room air conditioning.
The central air conditioning system cools your house or the entire building b circulating and showering the cool air through the different ducts that are installed within the building or your home. Hot air that is flying around your home or building will be actually sucked in the air ducts and would go to the air conditioning system so that in the end that hot air will be and would be transformed into something colder. Once the hot air is transformed to become cool air, it will be pumped back into the air ducts and start to circulate the entire building and house. Supply and return is the process that the duct system uses to constantly provide heated air to the air conditioning system and it also distributes the processed air to the ducts so that it would be transported to the different parts of the building without any hardship. The air that they produce constantly circles around the entire building and it does that until the desired temperature that the owner is met. Considering the fact that the entire house is at one solid temperature, the air conditioning system will continue to do this until the entire building is set at that temperature point.

Room air conditioning, or better known to everyone as window or wall air conditioners utilizes a system that only cools a room and won't have the capacity to cool an entire home unless one is inclined to buy more of these machines in order to cool the entire room which is not very practical at best. This type of air conditioning is installed on a wall or a window of a room in which it provides the room that it is in some cool air and that only applies to that room. Unlike the centralized air conditioning system, this system manages through the throwing out heat from the inside to the outside and in place spits in cool air to the room.
