Refrigeration

The next time you crave for an ice cold drink on a hot summer’s day, you have your refrigerator or freezer to thank for in indulging you on your refreshingly chilled beverage.

 

Refrigeration is the mechanical process in which heat is transferred from one location to another. It has many applications, including household refrigerators, industrial freezers, cryogenics, air conditioning, and heat pumps.

 

The most widely used application of refrigeration are for regulating the temperature in homes and buildings. It is estimated that around 5 percent of all the electrical energy used in the U.S. is expended to keep our homes cool. Refrigeration is also used food preservation in homes, restaurants and large storage warehouses. The use of refrigerators in kitchens for storing fresh produce allow them to be part of our meals year round, and allow fish and meats, which would normally spoil under room temperature, to be stored safely for longer periods of time.

 

For commercial and industrial refrigeration, it is used to liquify gases - oxygen, nitrogen, propane and methane, for example. In compressed air purification, refrigeration is used to condense water vapor from compressed air to reduce its moisture content. In oil refineries, chemical and petrochemical plants, refrigeration is used to maintain certain processes at their required low temperatures. For example, industrial refrigeration is used in alkylation of butenes and butane to produce a high octane gasoline component. Metal workers use refrigeration to temper steel and cutlery. In the transport of temperature-sensitive foodstuffs and other materials by trucks, trains, airplanes and sea-going vessels, refrigeration is a must.

 

How Refrigeration Works - The Refrigeration Cycle


The principle behind most refrigeration is quite simple. When a liquid evaporates, it absorbs heat in the process. 

 

To explain this in layman’s terms, let us take holding a cube of ice as an example. Although the body heat from our hand may not be enough to turn the water in the ice into its gaseous state, it is enough to liquefy the ice from its solid state into water. As this happens, our hand significantly cools down. This is because thermodynamic laws state that heat transfers from a warmer body to a colder body.
