Refrigeration evaporator

The evaporator is the second heat exchanger in a standard refrigeration circuit, and like the condenser, it's named for its basic function. It serves as the “business end” of a refrigeration cycle, given that it does what we expect air conditioning to do – absorb heat.

What is the function of a 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.

Which type of evaporator is used in refrigeration system?

3.1 Overview on shell and tube evaporator. Shell-and-tube evaporators are widely used in chillers, industrial refrigeration, and heat pumping applications. In refrigeration systems, the evaporator cools the fluids (liquid or air).

What is the function of the evaporator in a refrigerator system?

Evaporator: This is the part of the refrigeration system that is doing the actual cooling. Because its function is to absorb heat into the refrigeration system (from where you don't want it), the evaporator is placed in the area to be cooled.

What is evaporator and types?

Evaporators may be classified into falling film evaporators (in which evaporation takes place from the film interface with no nucleate boiling at the wall), nucleate boiling evaporators (in which wall nucleate boiling occurs over part or all of the heat transfer surface), flash evaporators and direct contact

What are the two types of evaporator?

The two general types of evaporators used in today's refrigeration systems are flooded evaporators and dry, or direct expansion (DX), evaporators.

What is 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 components of an evaporator?

The evaporator is mainly composed of two parts: the heating chamber and the evaporating chamber. The heating chamber provides the heat needed for evaporation, and promotes the vaporization of the liquid. The evaporation chamber completely separates the gas-liquid two phases.

How many types evaporator?

Types of evaporators slim evaporators ; cubic evaporators; two-flow evaporators ; floor-mounted evaporators.

What are the 3 types of refrigeration?

What Are the Different Types of Refrigeration Systems?

Mechanical-Compression Refrigeration Systems. The most widely used refrigeration cycle method is mechanical compression.
Absorption Refrigeration. ...
Evaporative Cooling. ...
Thermoelectric Refrigeration.

What are the four types of evaporators?

TYPES OF EVAPORATOR

Natural/forced circulation evaporator.
Falling film evaporator. ...
Rising film (Long Tube Vertical) evaporator. ...
Climbing and falling-film plate evaporator. ...

What are the four 4 types of refrigeration system?

Here are the different types of refrigeration systems:

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.

Where is evaporator located in refrigerator?

In the refrigerator, the evaporator is located in the freezer section.

What are the 3 types of evaporation?

There are three types of vaporization, and these are as follows: Evaporation. Boiling. Sublimation.

Why is it called evaporator?

It's called the evaporator because it's where the freezing liquid refrigerant takes on any heat from the air blown through it and changes into a gaseous state (evaporating it) before returning it to the air-conditioning condenser to shed the heat; the process is constantly repeated.

Which evaporator is best?

One of the more useful types of evaporators for difficult-to-handle materials is the agitated thin-film evaporator(Figure 8). Although tubular evaporators have been used successfully with a variety of materials, they have been less successful with heat-sensitive, viscous,fouling or high-boiling liquids.

Do refrigerators have two evaporators?

Dual evaporators are available on mainstream refrigerators from brands, including GE, LG, and Samsung. Dual evaporators tend to be more affordable than dual-compressors.

What is the name of the evaporator?

Evaporators are used to concentrate a solution. One example is the climbing/falling film plate evaporator, which is used to make condensed milk. Similarly, reduction (cooking) is a process of evaporating liquids from a solution to produce a "reduced" food product, such as wine reduction.

Is evaporator same as 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.

Is chiller and evaporator same?

A chiller uses a vapor compression mechanical refrigeration system that connects to the process water system through a device called an evaporator. Refrigerant circulates through an evaporator, compressor, condenser and expansion device of a chiller.
