There are four main kinds of air conditioners that I will be talking about in this article. They are: air conditioners for automobiles, central air conditioners, combination room and central air conditioners, and room air conditioners.
In automobiles, the unit of refrigeration can be found under the hood near the engine. The engine will drive the unit of refrigeration by a belt which is connected to the
engine. Air pipes put the conditioned air into the car.
Buses, however, usually have a separate motor to drive the unit of refrigeration. This unit can be found in either one of two places, in the rear of the bus or under one side
near the luggage area. The air conditioner can be found in the roof of the bus. It gives air to the seats through pipes that run along the roof.
In a railroad passenger car, there is either an electric motor or gasoline engine that will drive the unit of refrigeration. This unit can be found under the car. The air conditioner can be found over the entrance at one end of the car. The fans in the air conditioner blow the air through pipes that lead to outlets that are in the car.
Airplanes on the other hand need a special air-conditioning unit. A lot of these units are made of aluminum because it helps save weight. The refrigeration and air conditioning units in large planes can be found in the wings. In small planes, they can be found in the body of the plane. Air turbines are what drive the unit of refrigeration. Air
pipes put the conditioned air to different parts of the airplane.
Ships have refrigeration units that are installed in either the engine room or in a mechanical equipment room. The air conditioning units can be found throughout the ship. The air conditioning equipment used for ships has to be really strong to be able to hold up to the rolling and sloping motion that comes from the water. There are special
metals that are used to help prevent corrosion from the sea water.
Central air conditioners use either gas or electricity. They can give conditioned air to lots of rooms or to a whole building from one source. Fans will blow the
conditioned air through air pipes in the air conditioners then to the rooms.
Central air conditioners have some advantages over others. Everything that is needed to condition a room can be found in one place. This is good cause it helps to cut down on the cost of cleaning and repairing it. They can also give air of varying temperatures to different parts of a building.
Combination room and central air conditioners are used in large buildings. They are a combination of the advantages of both types. One of these kinds of air conditioners
has a central air conditioner that conditions the air outside. It will then circulate the conditioned air to a unit in each room. This unit will control the temperature and the amount of moisture in the air.
Another kind of combination air conditioner provides either cold water or a refrigerant that comes from a central refrigeration machine then to an air conditioner in
each room. Every air conditioner in each room has a fan, filter, and cooling coils that condition and circulate the air.
There is yet another kind of combination air conditioner that conditions a mixture of the air inside and outside. This air conditioner provides each room with cool,
conditioned air that comes through one pipe, and warm, conditioned air that goes through another pipe. In order to get the right temperature, there is something called a mixing box unit found in every room that mixes the two air streams. These conditioners allow you to change the temperature to whatever you want it to be.
Room air conditioners run on either electricity or gas. They can be found partly in the room that is being cooled. They are enclosed in a single cabinet. They blow the
conditioned air right into a room and they do not have any air pipes leading to and from them. The three main kinds are: console, self-contained, and window air conditioners.
Consoles are larger than window air conditioners and you can stand them on the floor. You have to put them near a window or a wall opening so they can get air from the
outside.
Self-contained air conditioners are the largest of all the room air conditioners.
They can be as big as seven feet tall, and they can cool a whole large room.
Window air conditioners are found in the lower part of a window. They can also be moved from window to window.
