Air conditioners and refrigerators are devices used to keep a space at a colder temperature than its surroundings. The main difference between refrigeration and air conditioning is that refrigeration, in general, refers to any process where thermal energy is taken away from a place and transferred to a place with a higher temperature. Air conditioning is a type of refrigeration where thermal energy is taken away from the air (typically in a room or a vehicle) in order to keep the air cooler.
What is Refrigeration:
Refrigeration refers to processes that take thermal energy away from a place and gives off that energy to a place with a higher temperature. Naturally, thermal energy flows from a place with a higher temperature to a place with a lower temperature. Therefore, refrigeration runs against the natural heat flow and so it requires work to be done. Refrigerator is a name that we use for devices that are used to keep food at low temperatures.
What is Air Conditioning:
Air conditioning is a type of refrigeration where thermal energy is taken away from the air in a large space such as a room or a vehicle. Air conditioners are fitted into rooms so that they cool the air inside them. Air conditioners also reduce humidity in rooms, because the water vapour in the room can condense around the colder parts of the air conditioner. The condensed water can be then drained off.
Difference Between Refrigeration and Air Conditioning:
Process
>Refrigeration is a process where thermal energy is transferred from a place with lower temperature to a place with higher temperature using energy, against he natural flow of heat.
>Air conditioning is a type of refrigeration which is used to cool large volumes inhabited by people.
Functions
>Refrigeration is concerned only with regulating the temperature of a volume of air.
>Air conditioning is concerned with not only maintaining the temperature of a volume of air, but also maintaining he humidity and purity.
