Which type of refrigeration system is used in domestic refrigerator?
can be stored at reduced temperatures. The most common domestic refrigerator uses a vapour compression refrigeration system for maintaining required storage conditions, even though a small number of refrigerators use the principle of triple fluid vapour absorption refrigeration system.
Which type of evaporator is used in domestic refrigerator?
The household fridges use plate surface evaporators . The coil is attached to the plate in the form of an evaporator. The internal and external surface of the finned evaporators are made of the same copper coil.
What is evaporator in refrigerator?
Evaporator. 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 are two types of evaporators found in household refrigerators?
The two general types of evaporators used in today’s refrigeration systems are flooded evaporators and dry, or direct expansion (DX), evaporators .
What are the types of evaporator?
- Natural/forced circulation evaporator. ...
- Falling film evaporator. ...
- Rising film (Long Tube Vertical) evaporator. ...
- Climbing and falling-film plate evaporator. ...
- Multiple-effect evaporators. ...
- Agitated thin film evaporators.
What is the difference between evaporator and condenser?
Evaporator Coils vs. Condenser Coils. The evaporator coil is the part of an air-conditioning system that removes heat and moisture from indoor air to cool it. The condenser coil takes that heat and releases it outside .
What are the two types of refrigeration?
- Evaporative Cooling. Evaporative cooling units are also referred to as swamp coolers. ...
- Mechanical-Compression Refrigeration Systems. Mechanical compression is used in commercial and industrial refrigeration, as well as air conditioning. ...
- Absorption. ...
- Thermoelectric.
Which gas is used in AC and refrigerator?
Complete answer: Freon is a non-flammable aliphatic gasoline which is used in refrigerators and air conditioners as the supply of Chlorine. Freon is a lower toxic gasoline which is also used as aerosol propellant. In the case of air, the conditioner Freon is located inside the copper coil of the air conditioner.
Which gas is used for refrigeration?
| Synonyms CFC (chlorofluorocarbon), HCFC (hydrochlorofluorocarbon), HFC (hydrofluorocarbon) | Safe Work Australia ES TWA Refer to specific compound. |

What is the principle of evaporator?
An evaporator is a device used in a process to turn the liquid form of a chemical substance, such as water, into its gaseous form – vapor . The liquid is evaporated, or vaporized, into a gas form of the targeted substance in that process.
Where is the evaporator in a refrigerator?
The evaporator coils sit in the back of the freezer compartment of a refrigerator and look like a radiator. The back wall of the freezer is actually the cover of the evaporator coil and can easily be opened with a screwdriver.
What is function of evaporator?
The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment . When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it.
Which is the simplest type of evaporator?
Batch pan evaporators are the simplest and oldest. They consist of spherical shaped, steam jacketed vessels. The heat transfer per unit volume is small requiring long residence times.
What is a dry evaporator?
An evaporator is called dry type when a portion of the evaporator is used for superheating the refrigerant vapour after its evaporation . ... The refrigerant from expansion valve is fed to these tubes. The liquid refrigerant evaporates inside the tubes and cools the air whose density increases.
What are the four types of evaporators?
These evaporators are available in four configurations: rising/falling-film, falling-film, forced-circulation with suppressed boiling, and agitated thin-film . For the last type, film thinning is achieved by a combination of fluid hydrodynamics and plate geometry, rather than by a mechanical device.
