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.

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.

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.

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.

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.

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.
