Everyone should be familiar with the two types of refrigeration (direct cooling and air cooling), and manufacturers are attacking each other’s shortcomings. It is true that the two refrigerator refrigeration methods have their own advantages, air-cooled refrigeration control fast, suitable for fast refrigeration. However, the defects of air-cooled type are also significant. Due to the addition of electric fans, they can not be prevented from bringing extra noise and power consumption. In addition, because of the constant wind, it is easy to cause the food outside dry signs.
Direct cooling without electric fan, naturally will not occur especially noise and power consumption, at the same time will not cause drying signs outside the food due to blowing. It sounds as if direct cooling has many advantages over air cooling. However, otherwise, the straight cold has a fatal flaw, that is, due to the release of cold air completely by air convection, low efficiency control, so that it is easy to freeze around the evaporator, to be regularly defrosting, abnormal bad luck.
From the previous use, the air-cooled type is mainly concentrated in Asia, and its main craft is also mastered by Japanese manufacturers. Straight ice boxes are common in Western Europe, and the main technology is also in the hands of a few large refrigerator companies in Western Europe. However, due to the merits of both air cooling and direct cooling, many refrigerator manufacturers have made certain improvements and fusion of their refrigerator products, and made some improvements to direct cooling and air cooling.
However, only some improvements are far from enough, so some refrigerator enterprises think of a kind of gathered air cooling and direct cooling advantages in a double system refrigerator. This type of double – system refrigerator has an air – cooled freezer designed for quick freezing without the dreaded frost – forming signs. As for food showing up as blow-dry, as long as it’s frozen, there’s no stopping it from happening, so don’t be too glum, just add a layer of plastic wrap.
Double-style refrigerators embrace the straight-refrigerated design, which is extremely good for keeping vegetables fresh, ensuring that they don’t blow dry for a long time, and keeping other foods fresher. But this type of double refrigerator is only used in high-end refrigerators, in a common refrigerator is not common.
In addition to the differences in refrigeration methods, modern refrigerators also carry a number of effects, such as some refrigerators accept computer control, some just accept the traditional mechanical way. Others accept a zero degree freeze zone, others have infrared deodorization, and some even switch between a freezer and a freezer. In fact, these are some special effects added after quenching, can only be used as a reference in choosing a refrigerator, not a decisive factor.
The first step in choosing a refrigerator is to choose the size that suits you. Bigger refrigerators don’t offer the same visual pleasure as TV sets, but rather higher power consumption, so buy the right refrigerator for you. For an average family of two, 190-220 litres is enough. Even for a family of three, 260-300 liters is definitely enough. No need for a bigger fridge unless you’re a crazy culinary enthusiast or an associate who fears poverty and buys food once a week.
In the choice of direct cooling or air cooling, my suggestion is that if possible, just choose the double product, so the effect will be the best, but the price will be much higher, depending on the strength of each person. If you have enough budget, you would rather not buy too big and buy a better performance, so that the effect will be better. If you can only buy direct cooling or air cooling, there is very little difference. If you need more rapid freezing effect, you will choose air cooling, and you need better vegetables and fruits to keep fresh with direct cooling.
Frequency conversion refrigerator is also a kind of advanced products in the sea. Like air conditioning, frequency conversion products will also bring better results, lower power consumption and more peaceful operation. Of course, the value of the expenditure is more expensive, no matter what the product, the principle of getting what you pay for is not going to change.
When choosing and purchasing, we should also pay attention to the problem of power consumption. Because the refrigerator volume is certain, it is usually not nominal by power, but only by daily power consumption or annual power consumption. As usual, now the refrigerator, within 300 liters, power consumption should not be more than 1 degree/day that is 365 degrees/day, do a good control can be controlled below 0.7 degrees/day, the time to choose to pay attention to the price and other aspects of the same situation, as far as possible to choose a small power consumption machine, so as to save a lot in use. However, under the same common circumstances, the power consumption of air cooling is slightly higher, and the partner who likes air cooling will suffer slightly higher power consumption.
