Many people use air conditioners whether at home or in their offices. But most people do not know how air conditioners work.
The air conditioners are basically similar to a refrigerator. The main difference is the fact that refrigerator is used for cooling only a small area while an air conditioner is used for cooling a larger area.
The air conditioners basically use the chemical that is used in the refrigerator to remove the heat from the air and hence replace the heat with cool air.
In understanding how air conditioners work, there are three main important concepts. As we all know, heat moves from warm to cold and also the boiling point of the refrigerant chemical changes with respect to the change in pressure.
This also means that if the pressure is higher when the boiling point is higher. Conversely, if the pressure is low then the boiling point is also low.
Then the refrigerant chemical will boil and then take in the heat from the environment that is surrounding it when its outside temperature is greater than that of the chemical.
In other cases if the surroundings of the environment are cooler than the refrigerant chemical then the process of condensation will take place and thus the chemical will condense and thereby becomes a liquid substance and thus will lose the heat.
The air conditioners work in the form of a cycle. It begins with the process of compression of the refrigerant which causes it to heat up and thus become a pressurized gas. The gas is then sent through coils to disperse the hotness of the air and then it changes the chemical into a liquid substance.
The chemical then goes in to a evaporator coil where it again gets converted in to cold vapor.
The heat of the air is thus absorbed and the air that is cooled is spread throughout the room or the building. The whole process is repeated again and again, this is how air conditioners work.
An air conditioner works in the same way as a refrigerator. The portable evaporative air conditioners that we see in homes make use of water to cool the air. They are not so much use in an area with high humidity as the air they blow out is very humid. That is, a special refrigerant gas such as Freon is heated and then cooled through coils to give the cold air. With a fridge, the cold air is contained in an insulated box; air conditioners blow the cool air out into your room.
A compressor is used to compress the gas, making it become hot and high-pressured. As it runs through coils, the heat dissipates and the gas turns to liquid. The next step involves the liquid Freon running through an expansion valve so that it turns back into a cold gas. The Freon is mixed with a little oil that helps to lubricate the inside of the air-conditioner.
Many air-conditioners also use cooling towers to help save on the cost of air-conditioning. These cooling towers are generally found on the roof or at the back of buildings. Basically they are of mesh with water running through it to help cool off the gas.

Air Conditioning Repair Training – Understanding How an Air Conditioner Works
Generally speaking there are three main components of an air conditioning system. In order to begin your air conditioning repair training you need to know exactly how each of these systems works and what are some early symptoms of failure in these components.
The first component is the compressor. Inside an air condition system is a collection of hoses and things that look sort of like radiators. Throughout these pipes and tubes flows Freon in both a gas and liquid state. The compressor is what powers and pushes the flow of all this Freon. By changing the size of the tubes the system forces the Freon to change from a gas to a liquid and back again
By doing this energy is expelled and absorbed, and when time properly can cool off air that is passed over the two other components. Generally speaking Freon needs to be added from time to time and the compressor pump needs to be checked to make sure that it is functioning properly.
The next component is the evaporator core. This is generally right after the Freon has been cooled. This component looks like a miniature radiator and usually has a fan attached onto it. The coils of the evaporator core should be cold to the touch and may collect some frost.
Air is blown over the coils, cooled, and then sent to the rest of the house or car. This can be a problem spot if the fan stops working or if the coils build up too much frost. Usually you want to make sure that everything in this section is free and clear.
The last component is the condenser. This part is where hot air from inside is cooled before it is sent back over the evaporator to be cooled. This system is important to pre cool the air and make sure that cold air is getting cooled at the evaporator. This ensures and even cooling of the air.
This system can be plagued by the same problems as the evaporator core, although frost build up is not one of the problems typically associated with it. Usually if there is a break down in this system in will not be noticed right away but can cause sever problems down the line. There you have some basics to start your air conditioning repair training.
