What is the principle of refrigeration?
The principle of refrigeration is to remove heat from one area (i.e inside your fridge) and locate it to another area (i.e outside of your fridge).
Air is not brought in from the outside of the fridge the heat is absorbed by the evaporator inside the fridge which has refrigerant inside it, this refrigerant at low pressure is at low temperature inside the evaporator so the heat from the product inside the fridge is absorbed by the evaporator (as heat always transfers from the hotter object to the colder object) which has a fan to circulate the air around the fridge.
Then the refrigerant is pushed around the pipework by the compressor to the condenser where the refrigerant is hot from the heat out of the fridge, because the outside air will be lower than that of the pressurized refrigerant the heat is absorbed by the ambient air which leaves the refrigerant cooler and lower pressure so when its back into the evaporator it can absorb more heat and expel it into the ambient air.
There are 5 main components in a normal refrigeration system like on your fridge:-
Expansion Device or Capillary tube
The compressor compresses the refrigerant gas. This raises the refrigerant's pressure and temperature, so the heat-exchanging coils outside the refrigerator allow the refrigerant to dissipate the heat of pressurization. As it cools, the refrigerant condenses into liquid form and flows through the expansion valve.
When it flows through the expansion valve, the liquid refrigerant is allowed to move from a high-pressure zone to a low-pressure zone, so it expands and evaporates. In evaporating, it absorbs heat, making it cold. The coils inside the refrigerator allow the refrigerant to absorb heat, making the inside of the refrigerator cold. The cycle then repeats.
carl von linde John Gorrie. His basic principle is often used in refrigeration today such as cooling caused by the rapid expansion of gases.
You will be well aware that all the refrigeration systems used today needs regular maintenance. All the refrigeration equipment maintenance is carried out by a well trained refrigeration technician. Commercial refrigeration is found in every food processing establishment. Hence the demand for the refrigeration technicians is also high.
Refrigeration was created in 1859
Refrigeration is the correct spelling.
yes they do need refrigeration because they can wilt and rot faster without refrigeration so yes
Institute of Refrigeration was created in 1899.

The refrigeration units take their power from the locomotive.
what are the advantages and disadvantages of refrigeration

Refrigeration has helped people by enabling them to safely store food. Without refrigeration, foods would spoil and have to be thrown away.
Package refrigeration equipment is a system that used for the process of refrigeration. Household refrigerators, industrial freezers, cryogenics, and air condition and big plants in industries for cooling purpose are the examples of package refrigeration equipment.
Compression refrigeration uses a compressor to increase the pressure of the working fluid after the evaporator. Absorbtion refrigeration uses heat (usually waste heat from another process) to raise the pressure.
Natural refrigeration is keeping food cold without using electricity or any power source. Once source of natural refrigeration is snow.
it helped cool the food to eat
Refrigeration slows down the breakdown of organic materials.
There are many brands of refrigerators. They include: Turbo Air Refrigeration, Continental Refrigerator, Delfield Refrigeration, Randell Refrigeration and True Refrigerators.
The difference between freezing and refrigeration when dealing with bacteria is that freezing stops growth and refrigeration only slows down the growth. Freezing also causes ice crystals to form and refrigeration only keeps food cool.
GEA Refrigeration Technologies was created in 2010-04.
All eggs, raw or hardboiled, require refrigeration.
What is the Material compatibility in relation to refrigeration oils?
Yes, after opening all cheese needs refrigeration
No, boyles law needs to be combined with Charles law in order to be relevant in refrigeration. In refrigeration we need to remember the role temperature plays on pressure/volume.
Why COP is used for evaluation of compression refrigeration system but not absorption refrigeration system?
cause its a gas
Floc in refrigeration oil is wax that has separated out from oil containing parathene.
1 ton Refrigeration = 3026 kCal / hr
the importance of refrigeration because when the heat is exesrted from lower temperature to higher temperture
SIC 3585 applies to REFRIGERATION AND HEATING EQUIPMENT.
It can probably last about 1 week without refrigeration.
by refrigeration . by compressing the gas and expanding to produce refrigeration.
Refrigeration and airconditioning mechanics assemble, install, service and repair industrial, commercial and domestic refrigeration and airconditioning systems in homes, shops, factories, office buildings and hospitals.

The main two refrigeration giants are Thermo King and Carrier
Once it's open, any mayo needs refrigeration.
yes it can be! "fruits and vegetables will go bad quickly without proper refrigeration"
All pickles need refrigeration, once the jar has been opened.
Ultrasound or thermoacoustic refrigeration uses a resonating sound wave to induce a thermal gradient.
1.The coefficient of performance is high.2.Less running cost.3.It has smaller size as compared to air refrigeration system for the given capacity of refrigeration.
The gas refrigeration was jointly invented by one Albert Einstein and his former student called LeÃ³ SzilÃ¡rd. The gas refrigeration that they invented had no moving parts and operated at a constant pressure.

John Gorrie was the man who found refrigeration while researching malaria.
1 Ton of Refrigeration (US) = 3024 kcal = 3.516 KWH
No. Ten hours is too long without refrigeration.
One tonnage of refrigeration or 1 TR equals to 4.7 hp
Refrigeration systems use CFC. They deplete ozone.
Hydraulic oils are substances that are hot, while refrigeration properties are cold.
Bananas do not refrigerate well. They get somewhat mushy after refrigeration. They can be used in baking, such as in banana bread.
No. Refrigeration only slows or stops bacterial growth. They will still be there when it is pulled out of refrigeration.
an air conditioning system, is considered high-temperature refrigeration and is used for comfort cooling.
In my experience, a tuna fish sandwich can survive for some hours without refrigeration - you can take one to school with you in your lunchbox - but for any longer period of time, yes, it would need refrigeration.
