In the refrigerator market, two technologies, air cooling and direct cooling, are not only the difference in refrigeration technology, but also a lifestyle choice.
This time, let's take a deep dive into these two types of refrigerators from multiple dimensions and see which one is more suitable for your home life.
1. Exquisite temperature uniformity
Air-cooled refrigerators:
Imagine opening the fridge on a hot summer day and hoping that every layer of food will enjoy even cooling. That's the advantage that air-cooled refrigerators bring.
Its fan is like a diligent courier, delivering cold air to every corner of the refrigerator.
This way, whether you're storing ice cream or fresh vegetables, you'll be able to maintain a consistently low temperature to ensure the freshness and taste of your food.
What's more worth mentioning is that high-end air-cooled refrigerators are usually equipped with multi-angle, multi-fan systems.
It's like creating an all-encompassing air-conditioning network inside the refrigerator to ensure that every inch of space is evenly cooled.
This design not only improves the preservation of food, but also allows for more precise temperature control inside the refrigerator.
Direct-cooled refrigerators:
Comparatively speaking, direct-cooling refrigerators are somewhat inadequate in terms of temperature uniformity. Because the refrigeration relies on the evaporator being in direct contact with the inner wall of the refrigerator, the temperature in the area near the evaporator will be significantly lower than in the area away from the evaporator.
It's like being in a large room, where you can only feel cool near the air conditioning vents, while the rest of the area is relatively warm.
Such a temperature difference not only affects the preservation effect of food, but may also cause some food to spoil prematurely.
2. Accuracy of temperature control
Air-cooled refrigerators:
When it comes to temperature control, air-cooled refrigerators once again show their technological superiority.
By precisely controlling the fan switch and air speed, the air-cooled refrigerator is able to quickly and accurately adjust the temperature inside the refrigerator.
It's like a flexible air conditioning system that can adjust the temperature at any time according to your needs, neither too high nor too low.
Even more impressive, many high-end air-cooled refrigerators are now capable of achieving precise temperature control of 0.1°C. This precision not only ensures the long-term freshness of the food, but also gives you more personalization options.
For example, you can set different temperature zones for different types of food to ensure that each food is in the best possible condition.
Direct-cooling refrigerators: In contrast, direct-cooling refrigerators are coarser in terms of temperature control.
Due to the limitations of its refrigeration principle, when the evaporator reaches the set temperature, it still needs to wait for the evaporator to warm up naturally.
During this process, the temperature inside the refrigerator may experience large fluctuations, which can affect the preservation of food.
Data:
According to market research data, air-cooled refrigerators are significantly better than direct-cooled refrigerators in terms of temperature control accuracy, and their temperature fluctuation range is usually controlled within ±0.5°C, while the temperature fluctuation range of direct-cooled refrigerators may reach ±2°C. This means that food stored in an air-cooled refrigerator retains its original quality and taste for a longer period of time.
3. The secret of food preservation
Air-cooled refrigerators:
While air-cooled refrigerators excel in terms of temperature control and uniformity, it also has a problem that cannot be ignored – food dries easily.
Due to the constant blowing of the fan, the moisture on the surface of the food can easily evaporate. It's like drying clothes on a windy day, and although it dries quickly, it also makes the clothes dry and hard.
Therefore, when using an air-cooled refrigerator, you need to pay attention to using plastic wrap or a crisper box to lock in the moisture and nutrients of the food.
Tips:
To make the most of the advantages of an air-cooled refrigerator and avoid its disadvantages, you can try to store your food separately and use proper preservation tools to keep it hydrated and tasteful.
For example, foods that need to be kept moisturized, such as fruits and vegetables, can be wrapped tightly in plastic wrap or placed in a well-sealed crisper box.
Direct-cooled refrigerators:
When it comes to food preservation, direct-cooling refrigerators show their unique advantages. Due to the absence of fan interference, the evaporation rate of moisture on the surface of the food is relatively slow.
It's like keeping food in a relatively closed environment, which can better lock in the moisture and nutrients of the food.
Therefore, when using a direct-cooling refrigerator, you usually don't need additional preservation tools to keep the food taste and nutritional value good.
4. Trade-off between noise and cost
Air-cooled refrigerators:
While air-cooled refrigerators offer many technical advantages, their noise problems cannot be ignored.
Both the rotation of the fan and the operation of the refrigeration system can produce a certain amount of noise, especially in the dead of night, which may be more noticeable.
In addition, due to the relatively complex structure of air-cooled refrigerators, their maintenance costs are also relatively high.
Therefore, when choosing an air-cooled refrigerator, you need to weigh its technical advantages against the noise and cost issues that may come with it.
Direct-cooled refrigerators: In contrast, direct-cooled refrigerators have significant advantages in terms of noise and cost.
Due to their simple structure and the absence of noise-prone components such as fans, direct-cooler refrigerators are usually very quiet during operation.
Due to its relatively low maintenance costs, it can also save you a lot of money over the long term.
Of course, this doesn't mean that direct-cooling refrigerators don't have any noise issues or maintenance costs, just that they're relatively more affordable and quiet.
The data speaks:
According to consumer feedback and market research data, the noise generated by air-cooled refrigerators during operation is generally higher than that of direct-cooled refrigerators.
Some high-end brands of air-cooled refrigerators use silent technology to reduce noise levels, but it is still difficult to completely eliminate this problem.
summary
When choosing between an air-cooled or direct-cooled refrigerator, you'll need to weigh it against your actual needs and budget. If you're after temperature uniformity and precise control, and don't mind paying a certain amount of noise and cost, then an air-cooled refrigerator can be a good choice.
And if you are more concerned about the preservation effect and affordability of food, and want to have a quiet environment, then a direct cooling refrigerator may be more suitable for you.
No matter which type of refrigerator you choose, you need to pay attention to proper use and care to prolong its life and improve the use effect.
