What are the different types of evaporators in refrigeration?
Types of evaporators
- slim evaporators ;
- cubic evaporators;
- two-flow evaporators ;
- floor-mounted evaporators.
What is a refrigeration evaporator?
A refrigerator’s evaporator coil is the part of the refrigeration cycle that actually makes the inside of the fridge cold. Once the refrigerant gas has gone through the condensing coils along the back of the fridge, it begins to cool down and re-enter a liquid state.
What are the four 4 classifications of evaporator?
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.
What are the parts of evaporator?
The main components of a rotary evaporator are: A motor unit for rotating the evaporation flask or vial that contains the user’s sample. A vapor duct serving as the axis for sample rotation, and a vacuum-tight conduit for the vapor to be drawn off the sample.
How do evaporators work?
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.
How many types of evaporators are there?
Following three types of evaporators are widely available in the market.
What is the main function of evaporator?
The main job of the evaporator coil is to cool the refrigerant so that it can absorb the heat. As the fan blows air over the coil, the refrigerant becomes cold and turns into a vaporous state.
Why evaporator is used in refrigerator?
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.
Is an evaporator a compressor?
The compressor pressurizes the refrigerant. The evaporator coil then allows it to evaporate from a liquid state to a gas, absorbing hot air inside your home. The evaporator coil doesn’t only help absorb heat. It can also pull moisture from incoming air and helps to make the room feel less humid.
Introduction to the Refrigeration Evaporators. For many people the evaporator is the main part of the refrigeration system and they consider other parts as less useful. The evaporators are heat exchanger surfaces that transfer the heat from the substance to be cooled to the refrigerant, thus removing the heat from the substance.
What are the different types of evaporators used in air conditioning?
The evaporators used for the refrigeration and the air conditioning applications have different types of construction depending on the application. Based on their construction the various types of evaporators are: 1) Bare tube evaporators, 2) Plate type of evaporators, 3) Finned evaporators and 4) Shell and Tube type of evaporators.
What is a plate surface refrigerator evaporator?
However, a plate surface refrigerator evaporator is found in different refrigerator systems than bare tube evaporators. This construction type is used over the bare tube coils. The fins are metal plates made from aluminum. The construction design of a refrigerator evaporator will depend on several factors.
What are the parts of a refrigerator evaporator made of?
The fins are metal plates made from aluminum. The construction design of a refrigerator evaporator will depend on several factors. The three main factors that play a role in which construction type is used in a refrigerator system: refrigerant and liquid-vapor, temperature, and pressure drop.
