Are you planning to buy a new refrigerator but confused about the difference between direct cool and frost free models? It’s important to explore both types of refrigerators in detail: what they are, how they work, their advantages and disadvantages. So whether you’re an experienced home owner or someone who’s just starting out with appliances like fridges, you should have all the information needed by the time you finish reading this blog post. Let’s dive right in and find out more about direct cool vs frost free refrigerator – whichever fits your needs better may become your next purchase!
Direct Cool Refrigerator
One of the most common refrigeration techniques for small refrigerators is direct cooling.To cool the evaporator coil in the direct cooling method, the refrigerating space must come into direct contact with it Consequently, there is uneven cooling throughout the refrigerator and so the water vapor freezes when it comes into contact with the cold surface. Because of this, Direct Cool refrigerators come with a button for manually defrosting, and only by using the button can you get rid of the ice.
One of the earliest forms of cooling, direct cool technology is primarily found in small refrigerators with one or two doors. The direct cooling process used in Direct Cool technology is based on the condensation of vapor and natural convection. There is no fan, blower, or other external source of forced airflow during the natural convocation cooling process. Natural convection cooling is also referred to as direct cooling because it relies on buoyancy or gravity to direct airflow.
Advantages of Direct Cool Refrigerators
More Chill Less Bill: Direct Cool Refrigerators consume less power than Frost Free ones thus resulting in lesser power consumption in turn saving money.
Less Heating: The exterior of frost-free refrigerators is exposed to heat because they typically have heaters for automatic defrosting; direct-cool refrigerators, on the other hand, do not experience these issues.
Cost Effective: Direct Cool ones cheaper compared to Frost Free ones since it needs manual defrosting and has less storage space.
Space Convenience: Since Direct Cool refrigerators come in mostly single-door they occupy less space and it’s ideal for small households.
Disadvantages of Direct Cool Refrigerators
Manual Defrosting: One of the main issues in Direct Cool that might make them go out of market is they need manual defrosting. If not done regularly the freezer is fully frosted and needs hours to defrost. Also the disposing of water collected from defrosting is an added task.
Capacity: Direct Cool refrigerators come mostly in single door and thus their storage space is less and is ideal for a small family only.
Frost Free Refrigerator
True to its name, frost-free technology literally keeps the refrigerator frost-free. Unlike direct cooling units that use a natural convection process, these units use electric fans to circulate cold air. These fans help distribute cold air evenly throughout the unit’s refrigerator and freezer, further preventing ice formation. This cooling technique is also known as conventional or indirect cooling.
Other advantages of frost-free refrigerators are – They have some advanced features like timer and thermostat. The thermostat constantly monitors the temperature of the refrigerator and automatically turns off the power when the device reaches the desired temperature. Some models have a heating system that melts any ice that may form inside.
Frost-free refrigerators mainly use the convection or indirect cooling method. Ice-free refrigerators have hidden evaporation coils (also called cooling coils) and a fan inside the refrigerator directs cold air into each compartment to maintain the required temperature.
To prevent direct contact of food with the evaporator coil (or cooling coil) and the formation of frost in the freezer compartment. This not only saves extra effort, but also helps preserve the original aroma and taste of the food.
Advantages of Frost Free Refrigerators
Auto-Defrost: No need for manual defrosting since the external fans and the heating system melts the ice.
Spacious: Since it comes in triple and side-by-side doors it can accommodate a higher number of products.
Capacity: More capacity means it can cater to the needs of a large family. A family of more than 5 members would find this refrigerator ideal for them.
Disadvantages of Frost Free Refrigerators
Power Consumption: It consumes more power than a direct cool one, and hence the electricity charges are more.
Expensive: Due to the use of latest technology and more features available it is costlier than a direct cool refrigerator.
Heating issues: Due to the external fan provided to melt ice the outer part of the refrigerator is always heated up and may need to be checked periodically.
Direct Cool Vs Frost Free Refrigerator- Comparison Chart
|Direct Cool||Frost Free|
|Variants||Direct Cool is available in single door||Frost Free is available in double, triple and side-by-side variants|
|Capacity||The maximum capacity range is 250 Liters||The maximum capacity here goes up to 650 Liters|
|Defrosting Method||Manually defrost by using the button||Auto defrost is available which prevents ice build up and also keeps the fridge clean|
|Price||Price is lower with starting prices of Rs. 6000||Comparatively expensive with starting price around Rs. 20,000|
|Freshness||Keeps food fresh for a short period of time||Food is kept fresh for more period of time than direct cool ones|
|Power Consumption||Consumes less power since they do not use external fans||Consumes more power since they have external fans for defrosting|
|External Heating||Due to manual frosting there are no heating issues||Since a heating system is in place for defrosting the external parts gets heated up|
|Cooling Method||Natural convection process is used to keep things cool||Electric fans to circulate cold air|
Both direct cooling and frost-free refrigerators have their advantages and disadvantages. When it comes to quality, storage, capacity and reliability, Frost Free models are the ones you should be looking at. Therefore, they tend to be more expensive than refrigerators with direct cooling technology.
Direct cooling models are ideal for small families, but are also cheaper and consume less energy than their counterparts. However, they require regular maintenance, which can also be boring and tedious.
If you don’t know which one to choose, hopefully this article has given you a clear idea about both models and their differences. What are you waiting for! Invest in one that meets your needs and is worth your money.
