Refrigeration System: Fridge, Refrigerator, Freezer, Chiller

We often hear a lot of these different terms, but never actually try to understand the difference between one another. Basically they all work on the same principle by drawing and transferring heat from the objects or source inside to the surrounding or sink so that the temperature of the inside is kept cool or remains below the ambient room temperature. Fridge, refrigerator, freezer and chiller are all common household appliances with a main function to perform almost similar tasks i.e. cooling and maintaining low temperature (refrigerating), but with varying features, capacities and different working operations. They are also available in the commercial range to meet the needs of businesses in the Food and Beverage industry, such as bar, restaurant, kitchen, lounge, pub, hotel, kiosk, catering, etc. Now let’s deep dive at some of the differences between the different suite of refrigeration system:Refrigeration System, Fridge, Refrigerator, Chiller, Freezer

Refrigerator (fridge)

Refrigerator and fridge refer to the same thing. Fridge is simply the colloquial term for refrigerator. Refrigerator is highly used as home, industrial and commercial appliance for preserving food and beverages by lowering the internal temperature. A fridge normally maintains a temperature of a few degrees above the freezing point of water e.g. 3 to 5 °C (37 to 41 °F), which is the optimal temperature range for perishable food storage. A refrigerator may come with a freezer as two separate compartments, and together as a combo they are still called a Refrigerator, however the colder compartment is known as a freezer.

Freezer

Upright Freezer 4 Door, Refrigerator 4 DoorFreezer units are typically used in households and in commerce and industry, they transfer heat from objects kept within an enclosed area by means of evaporation. It works on the same principle of refrigeration and an evaporating or cooling gas is used to evaporate heat from the objects. Freezers can drop temperature from -23 to -18 °C (-9 to -0 °F), although some freezer-only units such as those used commercially can achieve −34 °C (−29 °F) or even lower.

Chiller

Chillers are used to lower temperature of liquids within the range 2 to 5 °C (35 to 41 °F) by extracting heat from the liquids via vapor compression technique. To drop temperature of the liquids, compressor is used in chiller. Chillers are widely used in air-conditioning system as well as in many industrial applications like food and beverage processing, food catering, chemical processing, food storage and preservation, paper and cement processing and many more.
