How Air Conditioner Works???


How Air Conditioner Works???

One set of coils the condensing unit is outside the building and the other set The evaporating unit which inside the building. The compressor compresses cool low-pressure gas into hot high- pressure gas. As the gas then moves through the condenser outside the building, it cools down into a liquid. This liquid flows through the pipping and passes through an expansion valve, causing it to evaporate into a cold- low pressure gas as the liquid changes to gas and evaporates, it absorbs the heat from the inside of the building. A fan blows air across metal fins that have been chilled as a result of the heat being absorbed. This causes the room to cool down. The gas then continues to the compressor to continue the cycle.
