Comparison of advantages and disadvantages between air-cooled refrigerator and direct-cooled refrigerator

Air-cooled refrigerator and direct-cooled refrigerator have their own advantages and disadvantages. This paper will compare them from many aspects to help consumers better understand the characteristics of these two refrigerators.

Air cooling advantage

The air-cooled refrigerator has more fans to supply air, so the indoor temperature of the refrigerator is relatively average, and there is no great temperature change, so the refrigeration effect is naturally excellent.

Direct cooling advantage

Direct cooling depends on natural convection, so the temperature balance is poor and the cooling speed is low.

Air cooling disadvantage

The inherent defrosting cycle of air cooling, fans and multiple internal compensation heaters lead to higher power consumption and noise than direct cooling refrigerators, so air cooling certainly has no advantage in these two aspects under similar circumstances.

Direct cooling disadvantage

With large volume and many compartments, air cooling has an absolute advantage in cold distribution. If direct cooling is adopted, there will be technical obstacles and it will be difficult to achieve. The number of directly cooled rooms has basically reached the limit. If you want to make more rooms, you have to sacrifice some performance.

The dividing point between air cooling and direct cooling

The dividing point between air cooling and direct cooling is about 300 liters, and large-volume multi-chamber air cooling has advantages.

Energy consumption and noise of air cooling and direct cooling

The energy consumption and noise of air-cooled refrigerator are much higher than that of direct-cooled refrigerator. Therefore, boasting that air cooling has lower energy consumption and less noise than direct cooling is incomparable under the same conditions.
