    You have a room Out side the room there is a compressor. Take the refrigerant gas out side and compress it Take away its heat. Bring that inside the room. Let it expand taking heat from the room. Again take it out and compress it and remove the heat. Bring that liquid inside the room Repeat it. The gas makes it possible to transfer the heat from the room to outside the room.

    One reason why: The get cold, even very cold, but they remain fluid. You could use water but it freezes to ice and everything stops.

    they are the heat transfer material. when the carrier is allowed to evaporate, it cools down the container and thus removes heat from the target area (the warm air in the target area warms up the cold pipes, cooling the air). move that heat-containing gas outside the target area and then compress it, and it releases heat to the container (warms the pipes and thus warms the nearby air) and sends heat to the outside.

    We use fans to push more ambient air across the pipes that are either cold (inside) or hot (outside) to speed up the process.

    Basically employ phase change to convert heat energy into mechanical/kinetic energy and back, moving heat from one place to another.

    Its purpose is a transfer medium taking heat energy from one place and putting it in another place.

    Hydro fluorocarbons (freons) are the most efficient medium for this. Ammonia is also effective.

    HFC-134a is the most common one to be used today.

    It continually changes from a liquid to a gas as it is circulated between the external unit and the internal one by way of a compressor. As it changes its state it extracts heat from the room (or cabinet) and when it goes outside the reverse happens and it ejects heat.

    Coolant is the name.
