Direct Cool vs Frost Free Refrigerators
You’ll find that the difference between direct cool and frost free refrigerator units go far beyond price, but price is certainly a significant aspect. Direct cool refrigerators are typically much less expensive than the frost free versions. While the price gap has helped to keep the frost free refrigerator a consideration only for those who can splurge on their appliances, the gap between the models is shrinking, and is expected to continue shrinking over the next few years.
Frost free refrigerators, as the name implies, do not require any kind of manual defrosting. A small element is placed inside the unit that actually melts accumulating ice. This is done without interfering with the natural cooling cycle that is required to continuously refrigerate food.
A direct cool model produces the necessary chill through natural convection. It’s not as effective at keeping cold foods fresh as the frost free version. This is because the technology of the frost free refrigerator helps to maintain a more consistent temperature, especially in the humidity controlled fresh food bins. Frost free refrigerators also tend to scorch food with freezer burn less often, as the build up of ice is not as apparent, even on individual items.
The direct cool refrigerator requires fewer amp hours of electricity, when comparing the energy requirements of each model at the same temperature. It also cools the air and products inside the unit instantly. If you envision the refrigerators that store ice cream at the local market, you get a strong visual of the cooling cycle of the direct cool models. This is part of the reason that direct cool refrigerators are more popular than the frost free models. Over time, with changes in current technology, this is expected to change.
Manufacturers are focusing on the frost free designs more than the direct cooling designs, as the anticipated growth in popularity should become apparent in the next few years. Helping to make this a reality, the engineering and research departments that create these appliances are focusing on new innovative designs to reduce the energy needs, and increase the longevity of newer models of frost free refrigerators.
The life expectancy of the current models, of the frost free refrigerator, is greater than that of the current direct cool models on the market.
Marketing is shifting toward the frost free versions. It is thought that the improvements within the technology will make the direct cooling models obsolete within ten to fifteen years, with the exception of those designed for industrial purposes.
Summary:
1. Frost free refrigerators are more expensive, although the price gap is declining.
2. Frost free refrigerators do not require any deicing or defrosting through manual means. It is handled automatically.
3. Direct cool refrigerators use natural convection, resulting in instant cooling capabilities.
4. Frost free models are better at maintaining consistent temperatures, and keeping food items fresh for a longer period of time.
5. Direct cool refrigerators are more energy efficient.
6. Manufacturing and marketing are leaning toward making the direct cool version obsolete.
7. Direct cool is a popular choice for industrial use.
