Difference Between AC and Refrigerator

Ac is a short form for Air conditioner. The purpose of this gadget is to provide people with cool air when the weather or the temperature of the environment is hot. It is mostly used in the summertime.

A refrigerator is a machine that is made for the purpose of keeping any type of food and liquid cool and chill. Not only this but it is also used to protect things to last longer and turning bad or getting rotten by bacteria.

What is AC?

Ac is an abbreviation for Air conditioner. The idea for AC was first thought by Willis Haviland Carrier. He was an engineer and inventor and made this discovery in Brooklyn, the USA, in 1902.

AC helps in maintaining the balance of humidity and purity in the air. Aside from the use in home and offices to preserve food and safeguarding them from bacteria, it is also used for scientific and industrial research.

Though it is a very useful invention, the refrigerants that are released by Air Conditioner is quite harmful; it has been established that they are one of the main reasons for causing damage to the ozone layer and the reason for climate change.

What is Refrigerator?

The name "Refrigerator" came from the Latin verb "refrigerate", derived from the Latin adjective "frigus", that translates into "cold". The idea of Refrigerator was first thought of by William Cullen in the year 1755.

It retains materials in a confined, cool place. It has four basic parts in its compression cycle: A compressor, a condenser, an expansion device and then an evaporator. R134a is a refrigerant that is used in domestic Refrigerator as well as in automotive ACs.


Main Differences Between AC and Refrigerator

  1. Compared to it, Ac's main use is for human comfort, cooling out for equipment, infection control, artefacts preservation by balancing out the humidity in an environment.
  2. Refrigerators have to have a De-ice mode in them as to so that the heat exchanger doesn't clog with ice. Eventually, a point of time will come when one has to thaw the ice while pressing that mode button.

Both of these modern inventions have a lot of use in our daily lives, and people can not think to live without them in this generation.

They have become an everyday part of our normal lives. In the year 2000, Air conditioning/Refrigeration was named in the "10 greatest mechanical engineering achievements" of the 20th century.

AC is used to keep cool the temperature in the air for the comfort of people, and Refrigerator is used to keep cool the temperature of solids and liquids used for various reasons.
