In the twinkling of an eye again in July, during the hottest time of the year, the air-conditioner market has become extremely popular in shopping malls, offices, and homes in such hot weather. The sales of products are all the way up. However, the problem also followed, for many newly-graduated rental families, the installation of air-conditioning is not only expensive, moving installation and removal is also a trouble. In addition, for the elderly, children, or expectant mothers in the family, if you blow air conditioners for a long time, you will often have various health problems, and accidentally causing colds and colds. Then consider choosing an electric fan or air-conditioner fan at this time. These products have a relatively soft air supply and a relatively low price, which is more suitable for this group of people.
As a small home appliance, the technical content of electric fans is not high, but there are a wide variety of fan products currently on the market, and there are a variety of designs, such as floor fans, tower fans, ceiling fans, and pagers, leafless fans, and so on. The function is more diverse, whether it is a cooling air-conditioning fan, a DC inverter fan, or an air-purification fan, all have their own strengths.
Many consumers often consider products by subjective appearance or a single functional judgment in the purchase of small household appliances. So what kind of fan is the most comfortable to blow it? What kind of electric fan is more suitable for themselves? In order to answer questions, we specifically selected the market's four most popular types of electric fan products. Product prices range from a few hundred dollars to several thousand dollars, and through a series of comparative testing sessions, the most practical purchasing opinions are given.
The four electric fans we selected this time are:
1ã€Kadi Air Conditioning Fan: 4L capacity water tank, refrigeration, humidification, purification triple function.
2, Emmett Tower Fan: No leaf design, occupying a small space, three blocks of wind, a large angle swing.
3, millet frequency floor fan: intelligent APP control, DC inverter, get rid of the power line control, support 16 hours off the use of time.
4, Dyson air purification fan: Yan value burst table, no fan design, excellent air purification capabilities.
Before the start of the evaluation, we first look at the basic parameters of these four fans:
First, the introduction of evaluation standards
The four fan ratings are subjective and objectively tested. In addition to the product's face value, the product will be tested in terms of wind, wind speed, power, noise, and safety factor. Finally, the evaluation is combined with the evaluation. The actual use experience of the editor gives a fair evaluation of the overall performance of the product.
Second, which kind of electric fan is the most cost-effective?
Through a series of tests on four electric fans, although they all have their own advantages and disadvantages, Xiaobian must recommend it to everyone. This fan is priced at only 299 yuan, a cost-effective. The slim and compact design saves space, while the air volume is very large, which can play a role of rapid cooling and cooling. At the same time, it adopts a fanless design. The baby's family does not need to worry about it will hurt when it is used. Small baby. The only drawback is that due to the large amount of wind, the noise value is also relatively high. In the other three fans, the Dyson air-purifying fan also adopts a fanless design. It has a stylish and beautiful appearance and a small footprint. At the same time, the air is soft and comfortable, and it has a good air purification function. The price is 5190 yuan. It is still a little expensive, but if you are a fan of home aesthetics, then believe this air purification fan is a good choice to enhance your forcing.
First, subjective evaluation
Currently, there are many kinds of fan products on the market, and various designs and diversified functions inevitably make people dazzled. Many consumers often consider the products through subjective appearance judgment when they purchase small household appliances. . So for most consumers, what kind of electric fan is a good electric fan?
Xiao Bian made a survey. The vast majority of people think that the fan is good or bad. It has two aspects: wind volume and wind. There is no doubt that the amount of wind can be judged only by feeling strong or weak, and the wind feels uncomfortable to blow up, whether it is gentle and soft, and close to the feeling of natural wind. The air volume is large, it can relieve the heat and it is comfortable to blow. Then the fan is easy to use. With this principle, blind testing of our fans is about to begin.
Formally entered the test link, in order to fully play the strength of the four fans, while minimizing differences in evaluation, choose a closed meeting room, each fan in the evaluation are selected using the same basic angle and distance, open the maximum wind speed carry out testing. At the same time, Xiao Bian invited three editing team colleagues to participate in this blind test. (In other words, the participant wears a blindfold and does not know the order of appearance of the specific fan, and then reviews and scores after each experience.) The scoring system is set to a 40-point scale, which will be counted in the last minute by the Xiaobian and placed in the total test score.
Of course, before the test begins, you may think that our evaluation site is like this:
But in fact, our evaluation is very rigorous! So... our evaluation site is actually... this way, cough.
Test Results:
The appearance sequence of the four fans in the test was: 1 Emmett Tower Fan 2 Millimeters DC Frequency Floor Fan 3 Card Dianya Refrigeration Air Conditioner Fan 4 Dyson No Leaf Air Purifier. After a period of trial-and-blow experience, three editorial staff (do not lazy to kneel on the couch) scored and rated four fans respectively.
Editing No.1: The first and fourth paragraphs are effective. The first paragraph has a large amount of air and is very soft. It is very cool. I personally sweat very easily. So I personally prefer the first paragraph. Cool and cool, so cool. The fourth paragraph I think is more in line with the true feelings of the human skin surface; the remaining fan has a small amount of air, if close to the hair may have effects, it should be more suitable for a smaller space.
Editing No.2: The first fan is very suitable for use at high room temperature. The wind is strong and people can't stop. One word and cool. The second wind speed is relatively gentle, and the noise is not so great. I think it is more suitable for night sleep. The third wind is very weak, almost impossible to feel away from the distance, and it seems that it cannot be blown to the body. Although the fourth fan has a weaker wind, the softer wind is more skin-friendly and I feel that the wind is closer to the natural wind.
Edit No. 3: It may be the reason that individuals are not very sensitive or experience a short time. In addition to the first air volume of the four models, the air volume of the third model is not too small, and no other differences can be felt. However, through this test experience, it is indeed possible to feel that the noise is directly proportional to the wind force. For example, the first one, although it is particularly cool, it is also loud. But I do not know why the third paragraph sound is also quite large, and the wind has not yet closed!
　　
Summary: In this round of tests, the Dyson fanless fan and the Emmett tower fan had two higher scores. The Dyson fanless fan was soft and comfortable, close to the natural wind, while the Emmett tower fan The strong wind can quickly help you to eliminate heat. However, Xiao Bian also reminded everyone that it was the first time that the disease was cold. After the sweating, the body's pores grew. This time, because the cool air blows the fans, it is easy to cause colds and other discomforts. Therefore, do not pursue coolly.
Second, the objective evaluation
After the last round of subjective tests, we took a look at the objective ratings of these four electric fans. The objective tests were evaluated from the aspects of appearance, air volume, noise, etc. of the electric fan, allowing numerical values ​​to be spoken and more specific and rigorous.
1, the value of contrast:
In this face-seeing society, the value of the fan is also very important, regardless of color, style or footprint is very important. When consumers buy electric fan products in the store, they will often make initial judgments by the appearance of the product. Even if they look at the eye-catching affair, they will not be able to get through. What are the good products with excellent quality?
Cardia Refrigeration Air Conditioning Fan
First of all, let's take a look at the Kadiya Refrigeration Air-Conditioning Fan. The design of this air-conditioned fan is quite satisfactory. The rectangular body with a white and brown color scheme does not look very much at first glance. This fan has a net weight of 5.58kg, which is light and compact and does not have a large footprint. The bottom is equipped with a universal caster, which is flexible and convenient to move.
There is only a 4L water tank under the back, with 2 ice crystals, which can adjust the cold wind effect. The console has fewer buttons and the operation is simple and convenient.
Emmett Tower Fan
Emmett Tower Fan has a simple low-key appearance, with white and black colors coordinated. The lower part adopts a skirt-type design. The slender design of the fuselage covers an extremely small area. It can be easily placed at home or in the office. At the same time, this fan adopts a fanless design, even if the baby has friends at home can also be assured purchase. The functions on the operating table are relatively complete, and there are function buttons such as wind type, timing, and swinging head for selection.
Millet DC inverter floor fan
The next step is the millet DC inverter floor fan. This floor fan is made of anodized aluminum alloy pillars, plastic fan cover, net weight 3.74Kg, the overall is very light, all-white design looks very simple. There is a battery compartment at the bottom of the base. This is the part that most fans do not see. It is equipped with a 2800mAh battery, so you can get rid of the wires and move it around or even take it outdoors.
Behind the fan's motor there are two buttons, the top of the switch and switch gear, the rear of the switch. In addition to these two buttons, the entire fan has no other buttons. At the same time, this fan can be adjusted using smart APP, whether it is the swing angle or air volume can be remotely controlled.
Dyson Airless Fan
The last step is Dyson's leafless air purification fan. It has to be said that this fan's face value coefficient bursts the table, and the silver-white main color makes the entire purification fan look elegant and natural, and it is more convenient to match with the home environment. The whole body can be seen as a two-stage design with an upper fanless annular air deflector and a lower purifier base.
Switch button at the bottom of the very low position, the basic armpit can be pressed to press up is not so convenient, generally do not have it with a remote control. Here we have to talk about this remote control, its design is very intimate, you can directly by the magnet in the top of the purifier, like Xiaobian this nerve bar likes to throw things no longer worry about looking for Not to the remote controller.
Summary: In the evaluation of the four fan's face value, Dyson's leafless air-purification fan is undoubtedly the highest score. Not only is the design modern and full of excellent air purification capabilities, I believe it is a good idea for many home improvement design enthusiasts. . Emmett's tower fans win in a small footprint, and the slender body is ideal for a friend who lives in a tight environment.
Noise test:
The problem of noise pollution has to be taken into consideration, especially when people are still at night when the sound of some fans is becoming more pronounced and even disturbing people's sleep. In the actual test, we used a professional noise meter, but since we did not have a professional soundproof room, we chose the afternoon office as a test site to ensure that the entire test process was in a relatively stable sound environment. In addition, it should be noted that, under normal circumstances, the noise is in the range of 70 to 90 decibels, and the noise is too loud, but it will not harm the hearing and the body; the noise decibels are within 45-60 decibels, which can guarantee normal conversation; the noise decibels are 35-50. In the range, sleep is not disturbed. (Each fan we choose the lowest and the most high-end wind speed test)
The first is the Kadia Refrigeration Air Conditioning Fan. From the numerical point of view, the noise of this fan is still quite large.
Next is the Emmett tower fan. The maximum decibel of this product is about 70.4 decibels, and the lowest is 60.1 decibels. The noise is still relatively large under the maximum wind speed.
Millet DC inverter floor fan, the minimum value of this fan is only 45.5 decibels, even if the highest value at high winds is only about 65 decibels. Still relatively quiet.
Lastly, Dyson's leafless air purification fan. The noise figure of this fan is also relatively low, with a low value of 51 decibels and a high value of only 64 decibels.
Summary: In this round of testing, millet fans have the lowest noise level. And the noise value of the air conditioning fan of Kadiya has reached a maximum of 72 decibels, and it is still noisy at full speed.
Wind speed and wind range testing
The wind speed determines the influence scope of the fan itself and the user's actual feelings. In general, the larger the wind speed of the air outlet is, the wider the wind power can reach. Here we also use a professional wind tester to test, but also can intuitively see the size of the wind at the outlet through the GIF chart.
The first one to be tested is still the Kadia Refrigeration Air Conditioning Fan. It can be clearly seen from the numerical value that the wind power of this fan is very low and the cooling effect is not very good at the same time.
The second paragraph of the Emmett tower fan that was tested, this fan has a maximum wind power of 17.95m/s, and this result is already very good. At the same time, it can be clearly seen from the GIF diagram below that the ribbons are blown by a wide margin.
The third millet DC inverter floor fan performed well in the test. The maximum wind power reached 15.38m/s.
The last one to test was the Dyson Airless Fan. However, the wind power of this fan is not high, the maximum is only 9.2m/s.
Summary: Through the previous tests, we can see that the most powerful wind is the Emmett tower fan, and if you look closely at the parameter list, you will find that its power consumption is not the largest of these products, while the lowest wind speed is It is a Kadiya refrigeration and air-conditioning fan.
Finally, let's take a look at the ratings of these four fans.
This time, the four fans have passed the end of this review. Through the previous testing sessions, I believe that you already have a general understanding of the fan products of these four different categories. Overall, although each has its own advantages and disadvantages, the results are Look, Emmett has the highest rating. This fan is affordable, compact and convenient to occupy the smallest space, wind is good but the noise is not small. Dyson's leafless air-purification fan is suitable for home design enthusiasts. The value of a burst watch and a good air-purification function can make people's eyes shine. Millet DC inverter floor fan is better than light and small, but also can get rid of the power line. I believe you can always choose a suitable fan for you to spend the summer and send you cool.
