How Does A Dual Evaporator Refrigerator Work – A Complete Guide for Modern Families

Hello reader! If you’re looking into new refrigerators, you’ll be astonished by the number of cutting-edge features available nowadays. It is possible to find several different brands of refrigerators with dual evaporators. 

Don’t get confused. Don’t get stressed. I’m here to rescue you, ha ha!

I will go into more depth regarding “how does a dual evaporator refrigerator work”, and the advantages and providers of these refrigerators with dual evaporators in the next sections.

Available Types of Refrigerator Evaporators

Refrigerators with Single Evaporator

You may face two major drawbacks when using only one evaporator. To keep the items frozen, the evaporator must be kept at a low temperature. 

But the chilly, dry air in the freezer lowers saturation levels in the fridge portion, which is undesirable for many items since it reduces the amount of moisture sensitiveness in the air. Because of this, our ice cubes may taste like fish or other stinky things.

Refrigerators with Dual Evaporators

In order to address these issues, separate refrigerators with dual evaporators create two unique environments. One for freezing food and another for storing it on shelves preventing moisture loss.

The dual evaporator systems are a remarkable invention that places one cooling element inside the freezer and the other in the refrigerator. In order to maintain the steady temperatures in both portions of the appliance or refrigerator, this design has been used.

We have experimented with approximately hundreds of refrigerators with two evaporators in our ratings, which shows that the innovation is gradually making its way into more affordable models.

Purpose of an Evaporator Fan in a Refrigerator

After being drawn into the refrigerator and passed over the evaporator coils, cold air is distributed throughout the unit by the refrigerator evaporator fan. To get to the evaporator coils, the refrigerant must change its state from gas to liquid. 

As soon as the liquid reaches the evaporator coils, it turns cold, and this cold air is then circulated by the evaporator fan. Due to the refrigerant’s ability to absorb heat from heated air, it cools it down to a more comfortable temperature.

The freezer’s evaporator fan distributes the now-cold air. There is a damper in the traditional refrigerator that allows the cold air from the freezer to enter. As a result, chilly air fills both chambers.

How Does A Dual Evaporator Refrigerator Work?

A dual cooling refrigerator is a technical term for it. Evaporators are used to chill the food in the freezer area of most standard refrigerators. A fan is used to circulate the air. 

However, the cold, dry air in the freezer lowers saturation concentrations in the refrigerator portion, which is unfavorable for many items since it reduces the amount of moisture in the airflow.

This is excellent news for fresh produce vegetables stored in our crisper bins but terrible news for things in the freezer, which might incur “freezer burn” if humidity levels are too high. 

Dual evaporator technology make it easy to keep either part from overheating or overcooling. In order to prevent moisture from transferring from the freezer to the refrigerator, it is necessary to keep the air from mingling.

Why Is Having Dual Evaporators More Effective? 

The coil within our refrigerator’s evaporator creates the cold air inside. An evaporator, usually found near or within the freezer, disperses cold air into the fresh-and-frozen compartments. 

Refrigerators typically use sensors to control the amount of cold air that enters the refrigerator and exits the freezer. The problem with single evaporators is: 

Let’s assume we’ve just finished putting our goods in the fridge. The refrigerator’s temperature sensor is going to record a rise in temperature and request additional cold air. 

Because the evaporator is positioned in the freezer, our ice cream will be extra-hard and other items may get “over-frozen” as a result of this cooling, and ice taste bad.

Benefits of Dual Refrigerator Evaporator

Dual evaporator refrigerators provide the following advantages:

Cooling Capacity Variations

Refrigeration does not need as low of a temperature as freezing does. There is no need to wait for the freezer’s icy air to chill the sensitive foods or refrigerated foods, either. The evaporator system of many freezers is the same and good to go with the kitchen design.

“The freezer’s evaporator coils cool the cold air before it reaches the refrigerator’s condenser coils.”

The evaporator, on the other hand, can’t chill anything if there’s a problem. Since this freezer compartment is often much colder than the refrigerated compartment, the refrigerator is impacted. 

The refrigerator will not cool if the air vents are obstructed or the damper control is not working. There are certain advantages to using a twin evaporator system instead.

Maintaining a Consistent Level of Humidity

A refrigerator has two sections, each of which requires a different humidity level. Because the freezer is colder, the part in question requires less humidity or water vapor. 

Because it doesn’t need to be fresh, frozen items don’t need humidity. Humidity at freezing temperatures causes frost buildup, which is bad for frozen food quality.

Despite this, fresh food requires a slightly greater humidity level than the freezer. It extends the shelf life of the food.  Because it regulates the humidity in both rooms, twin evaporator systems are useful. In this way, all the compartments are kept at the correct humidity level.

Control of the Odor

It doesn’t matter how nice or awful the air is if we’re having the same cooling system. We can’t restrict the stench flowing from the freezer to the fridge, since it will spread. Keeping both compartments clean is the sole solution in this case.

“Dual cooling refrigerators are less expensive to run than dual compressor refrigerator.”

Drawbacks and Disadvantages of the Dual Evaporator

The most significant drawback is, unsurprisingly, the price tag. Dual evaporators aren’t worth the extra expense if we have a tiny family or don’t utilize our fridge-freezer at its maximum capacity. 

If you’re a caterer who works out of your house, having separate cooling systems can save you money in the long run since you’ll be capable of maintaining stuff fresh and clean.

Dual Evaporator Refrigerator Not Cooling – Quick Fix

Some of the dual evaporator refrigerator problems are discussed below –

Are you facing dual evaporator refrigerator problems? The main control board may be at blame! This is the most likely source of the issue.

However, if neither the freezer nor the refrigerator is chilling, then this is the case. There are two cooling systems in this style of refrigerator. So the fridge cools itself and doesn’t demand cold air from such a freezer.

Find the board in the back of the fridge. The J2 connection is readily visible on the circuit board. Set your multimeter to 14VDC before testing it.

“Using the meter’s black lead, check pin 3 on the board, and its red lead, check pin 8. A meter reading of 12-14VDC indicates that the control board has to be replaced.”

The single compressor or dual is another component to inspect. A single compressor powers both compartments, even though the fridge features a split cooling system. Then if the compressor breaks, the unit will no longer be able to cool itself down.

A faulty condenser fan motor is a possible cause of the compressor failing. A multimeter may be used to determine if the fan’s motor is functioning properly. The motor should be replaced if there is no continuity. Make sure the compressor is working properly.

“A good starting relay or overload may be the cause of a bad fan. Check for connection between the relay’s two-run terminals using a multimeter.”

Reinstall the relay if you can’t locate any current. It should also be replaced if it smells like it’s been burned or sounds when shaken.

These are the most common dual evaporator refrigerator problems discussed above. Solutions are also provided to overcome these dual evaporator refrigerator problems.

Frequently Asked Questions

How Do Refrigerators Keep Foods Fresh?

Unsealed foods retain their freshness longer when kept cold. Bacteria, which are present in all food, are slowed down by refrigeration in order to keep food fresh for a longer time. Bacteria may destroy milk in as little as two or three hours if it is left out in the open. 

When we lower the milk’s temperature, it will last for up to 10 to 12 days since the colder temperature in our refrigerator reduces microbial activity so considerably. Two of the most widely utilized methods of food preservation are refrigeration and freezing.

Dual Evaporator Refrigerators Are They Right for You?

Of course, it is.

Fresh fruits and vegetables benefit from higher relative humidity in the fresh food section. Freezer burn may be prevented by maintaining lower relative humidity in the frozen region. Onion or fish odors, for example, will not be able to move across sections.

Refrigerators with two evaporators keep food fresher, which is great news. Compared to a dual compressor refrigerator, which has two completely independent cooling systems, they provide many of the same advantages at a significantly cheaper price.

Is a Dual Evaporated Refrigerator Cooling System Worth the Price?

Dual cooling refrigerators and freezers may be pricey, and some may ask if the additional expense is truly worth having a system that utilizes a high rate of energy. 

It is up to us to decide whether or not we require a dual evaporator refrigeration system. For a small family, it’s probably not worth it. And if we have a moderate amount of people, let’s say – more than 4 or 5 people in the family, then, of course, it is worth it.

Do Refrigerators Need Dedicated Circuits?

It’s quite unlikely that we’ll be connecting anything to the same plug as our refrigerator. This prompts our question: Do refrigerators require their own dedicated circuits? 

Yeah of course! Before setup, a specialized circuit will be required by the refrigerator’s makers. Minimizes the danger of fire or explosion and restricts the responsibility of the producer. The criteria will be determined by the province in which we reside.

Editor’s Verdict

Two things mainly come into this part. The first, is, does it worth it? The answer is if I have a moderate number of people in the family – it is. Secondly, which one is worth it? 

I prefer LG and Samsung’s dual evaporator refrigerators. Because they come at a lower price and perform really outstanding.
