Difference Between Air Conditioning and Refrigeration

Air conditioning and refrigeration work on similar principles to lower or maintain an area's temperature. Both work by removing heat from a source-usually an enclosed space-to a different location known as a sink in order to lower the temperature of that space. However, there are subtle differences between them. We will about the basics of air conditioning and refrigeration in this article, as well as how they differ from one another.

Difference Between Air Conditioning and Refrigeration

What is Air Conditioning

Air conditioning, commonly known as AC, works by removing heat from the air inside a room and circulating cooled air back in. It has five main components, a compressor, a condenser, an evaporator, a receiver dryer, a fan, and a chemical refrigerant.

The compressor compresses the refrigerant gas to a high pressure before it enters the condenser, where it is cooled into a liquid by absorbing heat. After this, the receiver dryer removes the liquid's water content before a pump transfers it to the thermal expansion valve, where it is allowed to expand and turn into a low-pressure liquid before entering the evaporator, which then converts it into gas, which is pumped into the room by a fan.

You can regulate the fan's speed and choose the desired temperature for the room with an air conditioner. You can also use the air conditioner to increase the temperature of the room. This will shut off the cooling system, draw heat from outside, and pump hot air into the room.

What is Refrigeration

Refrigeration is the process of moving energy in the form of heat from a low-temperature medium to a high-temperature medium. This energy transfer process can be carried via heat, magnetism, electricity, lasers, or other sources in addition to conventional mechanical mechanisms (such as ice or electromechanical devices). It has four main components, compressor, condenser, evaporator, and refrigerant.

Refrigeration works on the same principle as air conditioning. The refrigerant is compressed by the compressor, which increases the pressure and temperature. Following its flow to the condenser, the high-pressure refrigerant releases heat outdoors. After that, the refrigerant travels to the evaporator, which cools the refrigerator by absorbing heat from inside. The cycle is repeated as the refrigerant continues to absorb heat from within and release it outside.

Difference Between Air Conditioning and Refrigeration

Key differences between air conditioning and refrigeration are discussed in the following table.

FeatureAir ConditioningRefrigeration
PurposeCools and dehumidifies air in a confined spaceLowers temperature to preserve perishable items
ApplicationUsed in buildings, cars, and other enclosed spacesPrimarily used in refrigerators and freezers
TemperatureTypically maintains a comfortable indoor temperatureMaintains temperatures below room temperature

Heat removalRemoves heat from indoor air and expels it outsideRemoves heat from inside the refrigerated space and expels it outside
Humidity controlReduces humidity in addition to coolingFocuses on cooling, with less emphasis on humidity control
Temperature rangeCools within a range suitable for human comfortCools to temperatures suitable for food preservation
SizeTypically larger units for home or commercial useSmaller units for household refrigerators and freezers
Energy efficiencyDesigned for efficiency in maintaining indoor comfortDesigned for efficiency in preserving perishable items

Conclusion

Air conditioners and refrigeration use the same technique to remove heat from confined spaces. Both work by removing heat from a source-usually an enclosed space to a different location known as a sink in order to lower the temperature of that space. The main difference between these two systems is how they are used. A refrigerator cools and preserves food, whereas an air conditioner cools the air within a room or a structure.
