An air conditioner and refrigerator works in the same way but the cooling of the small, insulated space inside of a refrigerator whereas the air conditioner cools a room, a whole house, or an entire business too. In air conditioners the chemicals are used that easily convert from a gas to a liquid and back again and this chemical is used to transfer heat from the air inside of a home to the outside air. The air conditioning machine has three main parts.
They are a compressor, a condenser and an evaporator in which the compressor and condenser are usually located on the outside air portion of the air conditioner and the evaporator is located on the inside the house, sometimes as part of a furnace. That is the part that heats your house. As the liquid changes to gas and evaporates, it extracts heat from the air around it and the heat in the air is needed to separate the molecules of the fluid from a liquid to a gas. The evaporator also has metal fins to help in exchange the thermal energy with the surrounding air. By the time the working fluid leaves the evaporator, it is a cool, low-pressure gas. Finally it returns to the compressor to begin its trip all over again.
