What are the functions of a refrigerator?

Last Updated: 18th April, 2020

The fundamental reason for having a refrigerator is to keep food cold. Cold temperatures help food stay fresh longer. The basic idea behind refrigeration is to slow down the activity of bacteria (which all food contains) so that it takes longer for the bacteria to spoil the food.

Simply so, what are the parts and functions of a refrigerator?

Major Elements of Refrigeration System and their Functions

  • Condenser. Condensation changes gas to a liquid form.
  • Compressor. The compressor's use is to pull the low-temperature and low-pressure vapour from the evaporator, through a suction line.
  • Evaporator.
  • Expansion Valve.

Also Know, what is the importance of refrigerator? Refrigeration slows bacterial growth. Bacteria exist everywhere in nature. They are in the soil, air, water, and the foods we eat. When they have nutrients (food), moisture, and favorable temperatures, they grow rapidly, increasing in numbers to the point where some types of bacteria can cause illness.

Also question is, what is the working principle of a refrigerator?

A refrigerator does not cool items by lowering their original temperatures; instead, an evaporating gas called a refrigerant draws heat away, leaving the surrounding area much colder. Refrigerators and air conditioners both work on the principle of cooling through evaporation.

What are the basic parts of a refrigerator?

In the refrigeration cycle, there are five basic components: fluid refrigerant; a compressor, which controls the flow of refrigerant; the condenser coils (on the outside of the fridge); the evaporator coils (on the inside of the fridge); and something called an expansion device.

Who invented the fridge?

US physician John Gorrie built a refrigerator in 1844 based on the design of Oliver Evans to produce ice for cooling the air for yellow fever patients. The first ice making machine used for practical food purposes such as meat packing and brewing was invented by James Harrison in 1857.

What is the function of compressor?

The function of a compressor is to increase the pressure, and corresponding saturation temperature (boiling point) of the refrigerant vapor to high enough level so the refrigerant can condense by rejecting its heat through the condenser.

What is superheat and why is it important?

"Measuring superheat is important because it can prevent damage to the air conditioner and make it run more efficiently. Superheat is the difference between the boiling point temperature of the refrigerant in the evaporator coil and the actual temperature of the refrigerant gas as it leaves the evaporator.

What part of a refrigerator makes it cold?

The evaporator is located inside a refrigerator and is the part that makes the items in the refrigerator cold. As the refrigerant turns from a liquid into a gas through evaporation, it cools the area around it, producing the proper environment for storing food.

What is a compressor fridge?

A compressor refrigerator has a small compressor unit that generates its cooling power, and this is where it gets its name. It is also called a 2-way refrigerator because it usually has two ways of providing power to the compressor: through a 12-volt battery or through the 240-volt mains power.

What is a refrigerator made out of?

The inner cabinet is made of sheet metal, like the outer cabinet, or of plastic. The insulation that fills the gap between the inner and outer cabinets consists of fiberglass or polyfoam. The components of the cooling system (compressor, condenser, coils, fins) are made of aluminum, copper, or an alloy.

How the compressor works in a refrigerator?

1. The compressor constricts the refrigerant vapor, raising its pressure and temperature, and pushes it into the coils of the condenser on the outside of the refrigerator. The refrigerant absorbs the heat inside the fridge when it flows through the evaporator coils, cooling down the air inside the fridge.

How would you describe a fridge?

A refrigerator is a machine for keeping things cold. It is sometimes called a fridge or an icebox. People put food and drinks in it, to keep those items cold or good (unspoiled) for a longer time. A refrigerator has a heat pump.

How does a refrigerator work simple?

How does a fridge work Wikipedia?

A refrigerator (colloquially fridge) consists of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from the inside of the fridge to its external environment so that the inside of the fridge is cooled to a temperature below the room temperature.

How does a 12v fridge work?

Refridgerators run off of compressors, but 12-volt coolers use something called Peltier cubes. When current runs through two dissimilar metals, the heat is removed from one and then pulled into the other. This cooler is packed with tiny little cubes that wrap around the inside of the cooler, behind the insulation.

How is a refrigerator made?

The plastic interior of a refrigerator is made using a process called vacuum forming. Large sheets of plastic are heated until soft, then pulled into a mould using a vacuum. Vacuum forming allow the interior to be formed as a single component with no joints, making it a very hygienic solution.

Why Freon gas is used in refrigerator?

A nonflammable gas, known as Freon, undergoes an evaporation process again and again within most refrigerators in order to keep the temperature low. The same cycle is used for air conditioners. The Freon liquid then flows through an expansion valve, which causes it to cool down until it evaporates.

How did the refrigerator change people's lives?

The refrigerator increased the efficiency of the icebox while ending the problem of melting ice in the kitchen. It also allowed people to buy and store fresh food products in a safer enviornment. As a result people were able to consume better foods for example fresh produce, eggs, and meats.

Why is the refrigerator an important invention?

It is mostly used to preserve food and other perishable items, preventing foodborne illnesses. It works because bacteria growth is slowed at lower temperatures. Methods for preserving food by cooling have been around for thousands of years, but the modern refrigerator is a recent invention.

How much does a refrigerator cost?

Getting the right refrigerator is a major component of a successful remodel. Generally, a top-mounted freezer model is the least expensive, costing between $350 and $600. Bottom-mounted freezer refrigerators may cost about $800 to $1,200.
