What is Evaporator Unit?
The Evaporator Unit is an important component for four major parts in the refrigeration system; Others are the compressor, condenser, and expansion valve.
Along with other spare parts, like a liquid receiver, filter drier, accumulator, oil separator, oil gauge, sight glass, solenoid valve, pressure controllers, etc, the whole refrigeration system is formed.
How does the evaporator unit work for cooling?
When the low-temperature liquid refrigerant which is just condensed by the condenser enters the evaporator unit coil, the refrigerant will exchange the heat with the air outside, evaporation.
At the same time, absorbs the heat to achieve the cooling function for the refrigeration system.
The evaporator unit has a heating room and an evaporation room.
The heating room provides the heat that the liquid refrigerant need when evaporation, to help the liquid refrigerant boil, then vaporize.
The evaporation room help to separate the gas and liquid of the refrigerant.
Miracle is the evaporator unit manufacturer for the past 20 years.
We provide different types of refrigeration evaporators, including the most popular DD, DJ DL series air cooled evaporator unit, dual discharge type evaporator unit, and small air cooler for the freezer and refrigerated cabinets.
At the same time, we provide the evaporator coil separately according to your drawings for different applications.
Evaporator Unit Type
Evaporator: It is an indispensable refrigeration component in the refrigeration system because it provides a usable low-temperature source for the entire refrigeration system.
There are two forms of hot exchangers in the refrigeration system: evaporator unit and condenser unit, but their roles are opposite.
The condenser emits heat, while the evaporator unit emits heat;
That is, the mixed refrigerant of gas and liquid in the evaporator unit absorbs heat from the outside, gradually evaporates until it becomes saturated or superheated vapor, and then leaves the evaporator.
According to the different heat exchange mediums of the evaporator, it is generally divided into liquid cooling, gas cooling, and direct cooling.
The gas is mainly air, and the liquid is mainly water, brine, and other refrigerants (evaporative condenser for cascade system).
Like condensers, there are many types of evaporator units for liquid cooling.
Such as shell and tube type (including the dry type evaporator unit and flooded type evaporator unit), immersed vertical tube type evaporator unit, or spiral tube type evaporator unit (usually used in ammonia systems), and plate type evaporator unit, Spiral plate-type evaporator unit, plate tube type evaporator unit, coil type evaporator unit, sleeve type evaporator unit, etc.,
According to different needs, there are many types, the following will introduce several common forms.
The evaporator for cooling air is relatively simple, mainly the exhaust pipe and air cooler.
Classification of Evaporator Unit:
Dry Shell and Tube Evaporator Unit
As shown in the figure, the evaporator unit heat exchanger has a straight tube and a U-shaped tube.
One type of heat exchange tube is a straight tube. The other is a U-shaped tube, which enters and exits on the same side.
The in-line arrangement of heat exchanger pipes is simpler and clearer.
When a single tube leaks, it can be blocked.
But the resistance of the end cap is relatively large;
The resistance of the elbow tube is relatively small, but it is more troublesome to clean.
If it leaks, it is difficult to replace the tube.
Advantages of U-tube dry evaporator unit:
The tube group can be assembled in advance, it can be drawn out, it is easier to clean the tube outside, thermal stress can be eliminated, the refrigerant distribution is uniform.
Disadvantages:
Different molds are required to manufacture the tube group, and longitudinal internal rib tubes cannot be used, and it’s hard to change the tubes when they are damaged.
Straight tube dry evaporator
Composition: shell, tube side, baffle, end cap, tube plate, etc.
If you want a higher heat transfer effect, you can try a smooth inner tube or a tube with longitudinal internal fins, and generally no external fin tube.
Advantages: low resistance, compact structure, low metal consumption, adjustable heat transfer area, etc.
Dry-type shell and tube evaporator, the refrigerant flows in the tube (tube side), the secondary refrigerant flows outside the tube (shell side).
Generally, expansion throttling (electronic expansion valve and thermal expansion valve), straight tube dry evaporator has a fast flow.
Generally, it is higher than 4m/s, so it is easier to return oil.
There is no need to consider the problem of oil return.
The oil return problem can be solved by returning the refrigerant to the gas and carrying oil;
The dry evaporator has a small refrigerant charge, usually 30-40% of the total volume of the straight tube dry evaporator, which is equivalent to 1/3 or less of the refrigerant charge of a flooded evaporator, with less leakage loss and better safety；
Dry-type evaporators must consider the return air overheating and have a certain degree of superheat. Therefore, about 20% of the evaporation channels in the evaporator take overheated gas, and the heat exchange of this part is very small;
The inside of the dry evaporator tube is refrigerant, the temperature is low, and the outside is the secondary refrigerant, which has a higher temperature than the refrigerant.
So the shell temperature is relatively high, and the loss of cold can be reduced; and because the water volume outside the heat exchange tube is relatively large, the cooling pipeline is immersed in water.
When the dry evaporator system working pressure changes, the water temperature will not fluctuate too sharply, there will be certain thermal inertia, and the system load fluctuation will be small.
This is very important for the refrigeration unit, and for the compressor unit, the working conditions are relatively smooth.
Because of the structure of the dry evaporator, it is difficult to clean, because it is difficult to clean, so the water quality requirements are higher.
Dry evaporators are usually used in fluorine systems and dry evaporator internal arrangement of copper tubes. This type of form is not used in ammonia systems.
Flooded Evaporator Unit
The flooded evaporator uses the same structure as the water-cooled condenser to feed liquid under the evaporator and return air above it.
Due to the internal design of the heat exchange tube, the flooded evaporator has a more flexible structure, and the liquid directly contacts the heat exchange tube, which has a good heat exchange effect and high heat transfer coefficient.
Both ammonia and fluorine systems use flooded evaporators, and ammonia systems use more.
In the past, flooded evaporators for fluorine used to have oil return problems, but more dry evaporators are used.
Now the evaporator refrigerating oil returns It can be solved, so the flooded evaporator used in the fluorine system is gradually increasing.
It mainly depends on the float valve and throttle valve to control the superheat, unlike the dry evaporator through the expansion valve to control the superheat.
Here is a certain space above the flooded evaporator without heat exchange tubes (usually 1 and 2 rows of space are reserved under the liquid surface without pipes), and some have an airbag on it, which is specially used for the gas-liquid separation to avoid air return with liquid.
Same as the condenser, because of the influence of heat exchange performance, the ammonia system cannot use copper pipes, usually DN32 or DN25 seamless steel pipes (smooth pipes).
The heat exchange coefficients of water and ammonia are not very different, and finned pipes are not used (Even if there is, it is a low-rib tube).
The structure is as shown in the figure above. Under normal circumstances, the copper pipes are arranged at a height below about 50% to 60% of the evaporator shell.
Generally, 1 to 2 layers of pipes are reserved above.
The principle is different from that of ammonia: the return gas on the ammonia has an airbag, which plays a role in liquid separation.
The Freon system controls the degree of superheat, whether it is an electronic expansion valve or an expansion valve, it controls the degree of superheat.
Although it is also used to return air on the upper side and supply liquid on the lower side, due to superheating’s control, there is usually no liquid in the next gas.
So there is no need to design an airbag for gas-liquid distribution.
The liquid level of the system in normal use is about 50% to 65%.
As shown in the text, there is usually an ultra-high level alarm at about 2/3 of the volume, and an ultra-low level alarm at about 1/3 of the volume.
If the valve of the system’s liquid supply pipeline fails, the liquid level will be excessively high, and there may be a possibility of liquid shock when the machine is turned on again;
It may also cause the liquid level to be extremely low, resulting in insufficient heat exchange area and affecting the cooling effect.
The following describes the ejection and oil return technology.
Ejection and return of oil is a new technology these years, see the picture below.
Evaporator Unit Ejection Technology
The structure of the nozzle is relatively simple, as shown in the figure. There are many types of high-pressure liquids used.
In addition to conventional high-pressure exhaust, you can also consider using high-pressure liquids, or even high-pressure oil, which is the high-pressure oil below the oil.
Some nozzles are not high-pressure fluid, but the return air of the compressor.
The return air is set up with a throttle nozzle in a certain place so that the nozzle is throttled to produce high speed and form negative pressure, the oil-rich layer is drawn from the liquid surface of the evaporator.
The oil return usually uses 2 to 3 holes (see label), and the oil is taken about 50-150mm below the liquid level at different liquid levels.
Taking the oil at this position can ensure that it is a pure liquid without gas, and can ensure a relatively large oil content.
If the oil fetching point is too high, the liquid level will boil violently, which may cause air to enter the oil return pipe and affect low pressure.
If the oil return pipe goes down too much, it is pure refrigerant liquid, and it will not function as oil return.
Therefore, the liquid is generally taken in the interval of about 100mm below the liquid surface (oil-rich layer), where the oil content is more, and then it is returned to the system through the ejector pump.
Immersion Cooling Liquid Evaporator Unit
Immersion cooling liquid evaporator unit (can be put in water)
Immersion cooling liquid evaporator units are usually used in large-scale, open-type refrigerant systems. Generally, brine-based block ice systems use more.
There are usually two types of evaporators unit for immersed cooling liquid: one is a vertical tube type, and the other is a spiral tube type.
Roughly the same, mainly because of the different tube structures.
The feature is that the equipment is placed in a lot of water, the water circulation is particularly large, it is not easy to freeze, even if it is frozen, it will not freeze the tube.
The evaporator unit whole equipment is open, easy to observe, operate, maintain, and repair.
Due to the large amount of water, the hot load of the refrigeration compressor is relatively stable, the working conditions are not changed quickly, and the thermal stability is better.
A large amount of water has a certain cold storage function.
The electricity price of the peak and valley is used (more cold or latent heat at night), there is a certain degree of economy.
The riser and spiral tube types are generally used in ammonia systems; the serpentine tube type evaporator unit is generally used in fluorine systems; the spiral evaporator unit coil type is more commonly used in small equipment.
Vertical Tube Evaporator Unit
The vertical tube evaporator unit of an open system is not suitable for volatile organics, but suitable for non-volatile inorganics, such as sodium chloride and calcium chloride.
This kind of riser-type equipment is usually placed in a water tank made of six thick steel plates or directly made of reinforced concrete.
A certain flow channel is formed in it, and the evaporator unit is stirred with a pump to exchange heat.
The structure is simple. Because the riser-type evaporator unit uses too much steel and the heat exchange effect is relatively poor, it has been gradually replaced by spiral pipes.
Main Parameters of Standpipe Heat Exchanger Evaporator Unit:
The general heat transfer coefficient can reach 520～650W/㎡.℃, this kind of low-temperature water is mainly used in central air conditioning.
In the saltwater system, the general heat transfer coefficient can be 450～550W/㎡.℃, because the saltwater is viscous and fluidity is small, the heat transfer coefficient will be smaller.
This type is mainly used in low-temperature block ice salt pools. The heat transfer temperature difference is generally 4 to 6 ℃. The temperature is lower, and the value can be higher.
Spiral Tube Evaporator Unit
Main Parameters of Spiral Tube Heat Exchanger:
In the spiral tube heat exchanger freshwater system, the general heat transfer coefficient can reach 550～700W/㎡.℃.
In the spiral tube heat exchanger saltwater system, the general heat transfer coefficient can reach 500～600W/㎡.℃.

What is an Evaporator Coil?
The evaporator coil is the core of the evaporator unit which is one of the major components of condensing units.
The evaporator coil is consists of copper pipes and aluminum fins, with the cover and fan motors, that form the complete evaporator unit.
We can see it in the air conditioner, cold room units, heat pump, freezer, refrigerators, etc. It has a very wide application.
What is the function of the evaporator coil? It absorbs the heat from the air of your home or cold room or freezer and produces cold air.
How does it work? The evaporator units consist of one or several sets of evaporator coils: when low-temperature liquid refrigerant enters the evaporator coils and flows.
Through the wall of the tube, the hottest boiling liquid (evaporation) of the medium (air or water) around the coil is used to reduce the temperature of the medium around the coil or to maintain a certain low temperature, so the goal of cooling is achieved.
Because of this, the evaporator coil should be placed in the space medium that requires refrigeration.
For example, The evaporator unit of the refrigerator or freezer is placed inside of the refrigerator and freezer;
The evaporator of the room air conditioner is placed inside the wall of the air-conditioned room.
It is also used as an air cooler to produce evaporator coils of chillers that produce low water (called cold water in the project) and placed in the shell box where cold food water emerges.
Refrigerant keeps the temperature and pressure unchanged while boiling liquid in evaporator coil to gas.
The corresponding temperature and pressure are called evaporation temperature and evaporation pressure.
The evaporation temperature increases with the increase of the evaporation pressure, and they have a confirmed correspondence.
