What is the scientific principle of refrigerator?
The Refrigeration basic principle is that with the aid of a heat pump, the refrigerant is being compressed to the condenser and capillary tube thus increasing its temperature (50-60°C) and pressure (750 kPa) in the refrigerator being cooled down by the condensing unit to 32°C depending the existing ambient temperature.
What is refrigerator and examples?
Something that refrigerates; esp., a box, cabinet, or room in which food, drink, etc. The definition of a refrigerator is an appliance or room that is used to keep foods cool. The place where you store your milk is an example of your refrigerator.
What are the applications of refrigerator?
Applications of Refrigeration in 7 Different Industries
- District Cooling.
- Electricity Production.
- Chemical and Petrochemicals.
- Food & Beverages.
- Data Centres.
- Other industries.
How are refrigerators classified?
Methods of refrigeration can be classified as non-cyclic, cyclic, thermoelectric and magnetic.
What are the basic operations of a refrigerator?
Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas. This process, called evaporation, cools the surrounding area and produces the desired effect.
What are the advantages of refrigerator?
Refrigerators provide cooling, which is necessary to keep your food fresh and safe. In the summer season, refrigerators also keep your water and other drinks cool so that you can enjoy drinking them to the best. They also have freezers which let you freeze water into ice, which can be used for many other purposes.
What gas is used in fridges?
Fridges used to use a gas called Chloro-Flouro-Carbon or CFC, but the newer models tend to avoid these due to them being harmful to the atmosphere. Instead, your fridge probably uses another type of gas called HFC-134a, which becomes a liquid at -26.6 degrees Celsius.
What is wattage of refrigerator?
The average home refrigerator uses 350-780 watts. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it. Different types of fridges have different power requirements.
Which is one of the basic principles of refrigeration?
This is another basic principle of refrigeration. The evaporator transfers heat into the refrigerant; the refrigerant transfers this heat to the condenser; the condenser transfers the heat to a cooling medium (such as water or outside air). Conduction is the flow of heat through a substance by contact of particles.
How does the working principle of a refrigerator work?
The working principle of a refrigerator (and refrigeration, in general) is very simple: it involves the removal of heat from one region and its deposition to another.
What to know when working around a refrigeration system?
When you work around the refrigeration system – or any part of the HVAC system – remember these principles: • You are dealing with electricity, heat, pressures, and possibly toxic gases. Don‘t start or stop equipment, touch tubing, adjust valves, or open lines unless you really know what you are doing.
How does the material in a refrigerator cool?
(Photo Credit : Wikipedia Commons) This part cools the material stored in a refrigerator. It consists of finned tubes (made of metals with high thermal conductivity to maximize heat transfer) that absorb heat blown through a coil by a fan.
