Direct Cool Refrigeration: A Technology With Decent Benefits
Candy Direct Cool Refrigerator
One of the two basic types of procedures employed in residential freezers is “direct cool” technology. Direct-cool refrigerators generate cooling using natural convection through cooled surfaces in the insulated chamber. The water vapour that comes into touch with the cooled surface freezes. As a result, opposing to frost-free units, direct-cool units need manual interior defrosting. Direct cool is less costly to produce and operate since it uses less energy than frost-free refrigerators.
Difference between the Direct Cool and Frost Free Technology
- Frost-free freezers do not need any manual deicing or defrosting. It is dealt with automatically.
- Frost-free freezers are more expensive, while the price difference is narrowing.
- Manufacturing and advertising are working together to make the direct cool version redundant.
- Direct-cool refrigerators use less electricity.
- Direct cooling is a popular industrial option.
- Direct cooling employs natural convection to provide immediate cooling.
- Frost-free models are more effective at maintaining constant temperatures and keeping food fresh for a longer amount of time.
Direct Cooling properties:
- The refrigeration happens due to natural circulations of cool air – without the need for external intervention
- Frost accumulates in and around the freeze box and must be manually removed.
- Frost forms inside this type of refrigerator due to the presence of water vapour.
- A knob or defrost switch is included in the refrigerator for manual defrosting.
Pros and Cons of Direct Cool refrigeration Systems
| Pros | Cons |
| Good for a family size of 2 to 3 | It is a rigorous task to clean and defrost the ice regularly |
| Efficient in keeping food fresh for long | The inside temperature is difficult to control |
| It is energy efficient in a way it does not consume a lot of power, and it is economical for recurring usage. | Limited features. Only restricted to single door fridge |
| Low maintenance comes along with the point mentioned above | Not suitable for large families |
| The outer part of these refrigerators or not prone to heat; as a result, it reduces the chance of damage | |
| Budget-friendly option compared to other forms of refrigeration | |
| They are beneficial in locations with frequent power outages since the fridge stays chilled thanks to the ice within. |
Choosing Direct Cool Technology over Frost Free Technology
As is seen in the chart, one of the most obvious benefits of direct cool refrigerators is that they are significantly less expensive than frost-free fridges. They are easily accessible and ideal for small families, offices, and businesses. Another major benefit is that they are power-saving and do not take a huge amount of energy, making them cost-effective to maintain. This is primarily because no external cooling fans are used. Compared to frost-free at the same temperature, it consumes less amp power and energy.
Users will rarely have heating problems while utilising direct cool refrigerators since the convection mechanism that occurs inside the fridge is highly natural. However, this can be a minor issue when users use frost-free refrigerators.
Another big advantage that direct cool refrigeration brings to the game is keeping food for a longer period. This may appear contradictory, but it applies specifically to those with a high number of power outages. This happens because of the formation of ice. Since the consumer will be experiencing more blackouts, the fridge will be out of power plenty of the time. Therefore the only option to maintain the food at the proper temperature will be to use the ice that has formed.
Candy 170L is such a refrigerator that provides Direct-cool Single Door Refrigeration with Turbo Icing Technology that helps form ice in 60 minutes with 170 litres, appropriate for a small family. The 2-star energy rating with 208 Kilowatt Hours of energy consumed per year indicates the energy efficiency to some extent.
