Direct Cool Vs Frost Free Refrigerator! The debate is going on for a long time. Consumers are still confused between the two and can not figure out which one is the best.
So in this article, let’s settle the battle and find out the differences between Direct Cool Vs Frost Free Refrigerators.
Refrigerator technology is evolving and refrigerators are getting smarter day by day. Gone are those days when you need to waste your weekend cleaning ice from your refrigerator.
Modern refrigerators can do that by themselves and also automatically. That’s what frost-free refrigerators are all about.
So before going into detail about the differences between frost-free and direct cool refrigerators, it would make sense if we learn a little bit about these technologies.
What Is A Direct Cool Refrigerator?
Direct cool refrigerators, as the name suggests use natural convection for cooling. There is no external aid. That is why you can not control the cooling distribution. Some areas will be too much cool and some areas may not be cool at all.
This is the reason, you will notice scattered ice in direct cool refrigerators. You will have to manually clean the ice or frost frequently, otherwise, your refrigerator won’t function properly.
One of the biggest problems with direct cool refrigerators is that food can get easily spoiled due to uneven cooling. But on the other hand, it consumes less energy as it does not have to do extra work of defrosting ice.
Direct cool technology is found mostly in single-door refrigerators
Advantages Of Direct Cool Refrigerators
- Consume less power
- Cheap price tag
- Simple design
Disadvantages Of Direct Cool Refrigerators
- Uneven cooling
- Chances of food getting spoiled
- Frequent manual defrosting required
What Is Frost Free Refrigerator
Frost-free refrigerators use force convection for cooling. So there is an equal distribution of cooling inside the cabinet. Due to this, there are fewer chances of scattered ice formation. That is why it is called a frost-free refrigerator.
Even if the ice is formed, there is a sensor that can detect it and easily defrost it. For defrosting, the refrigerator uses heating coils that melt the ice and drain it through a drain pan. So ultimately won’t see any ice inside the refrigerator.
Advantages Of Frost-Free Refrigerator
- No frost inside the cabinet
- No need for manual defrosting
- Food remains cool and fresh for a longer time
- Even cooling ensures that no food item is getting more cooled or less cooled.
Disadvantages Of Direct Cool Refrigerators
- Bit expensive but the gap is narrowing down due to the tough competition
- Servicing frequency is more
Frost Free Vs Direct Cool Refrigerators
Let us find out the differences under different parameters so that it is easy to understand.
1. Cooling Mechanism
As I said, direct cool refrigerators use natural convection whereas frost-free refrigerators use forced convection.
That is why you may notice that in direct cool refrigerators, you will get localized cooling instead of even cooling in frost-free refrigerators.
Many people get confused with localized cooling thinking that a direct cool refrigerator cools better than a frost-free refrigerator. But it is totally a wrong concept.
2. Power Consumption
Frost-free refrigerators have fans, heaters, sensors, and other extra parts that consume more power whereas direct-cool refrigerators do not have those parts.
So if you are power conscious person, then definitely you should go for direct cool refrigerators.
3. Freshness Of Food
If you consider for a shorter period then direct cool refrigerators cool faster but they can not retain the freshness of the food for a longer period of time.
Whereas frost-free refrigerators can retain freshness for a long time due to forced convection and even cooling mechanisms.
4. Heating Concern
As you know that a refrigerator can not produce air. It can only take the hot air from inside and dump it outside.
So naturally, the outside of the refrigerator will be hot irrespective of whether it is a direct cool refrigerator or a frost-free refrigerator.
But in the case of a frost-free refrigerator, the exterior gets really hot when the defrost cycle is running as there is a heater that defrosts the ice. In direct cool refrigerators, there is no such heater.
5. Design And Space
Direct cool refrigerators are simple in design and have fewer parts. However, it needs at least 1-1.5 feet of space behind the refrigerator for the natural convection of air. Otherwise, the machine won’t cool properly.
In the case of a frost-free refrigerator, it uses a fan for cooling. So there is no such requirement for spacing at the back of the refrigerator. But it is advisable to keep free space for better cooling.
6. Condenser Coil
Direct cool refrigerators have an exposed condenser coil as it depends on natural air for cooling. But in the case of frost-free refrigerators, condenser coils can be covered with a back panel as it depends on forced air for cooling.
That is why, if you are living in a city like Delhi or Chennai, it is better to buy a frost refrigerator as natural cooling would be a problem during summer.
Maintenance costs will be more in frost-free refrigerators due to the forced air circulation and defrosting mechanism. You may also need frequent maintenance compared to direct cool refrigerators.
Cost is definitely high for frost-free refrigerators as it comes with auto defrosting technology, forced air circulation, and many other features.
But the investment is worth it if you want to avoid the weekly hassle of cleaning the ice and keeping your food fresh.
Difference Between Direct Cool Vs Frost Free Refrigerator
|Direct Cool Refrigerator
|Frost Free Refrigerator
|Uses the natural convection of air for cooling
|Uses forced convection of air for cooling
|Cannot keep food fresh always
|Can keep food fresh always
|Consume less power
|Consume more power
|Simple design as there is no heating mechanism
|Complex design as it requires heaters, drain pans, etc.
|Manual defrosting is required
|Defrosting is an automated process in frost-free refrigerators
|Exposed condenser coil as it depends on natural convection
|The coil can be covered as it uses a fan to suck air
|The exterior does not get hot
|The exterior can get really hot when the heater is running
|Capacity ranges are between 50-200 liters
|Frost-free refrigerators are available in wide capacity ranges
|Less sound as there is no forced convection
|More sound due to forced convection
|Available mostly in single-door refrigerators
|Available in almost all types of refrigerators
|Good for small families
|Can be used for small to large families
|Price is less
Conclusion: Direct Cool vs Frost Free Refrigerator
Trust me, the little bit more investment is worth a frost-free refrigerator as these will eliminate your daily hassles of cleaning the ice. The even cooling keeps your food fresh too for a longer period of time.
Unless you are very tight on budget, I don’t feel there is any reason to choose direct cool refrigerators over frost-free refrigerators. However, both types of refrigerators have their own benefits and drawbacks.
