Can the air conditioner fan cool?
"More than 500 yuan, of course, it is impossible to be a real air conditioner." Mr. Wang, a Beijing-based distributor of Lianchuang air-conditioning fans, said in a word, "The air-conditioning fan does not have a compressor and does not use Freon, regardless of the structure or principle. The air conditioner is far away and has a closer blood relationship with the electric fan." No compressor does not need Freon, what is the air conditioning fan cooling?
The air-conditioning fan is actually an electric fan equipped with a water-cooling device. The built-in water pump keeps the water circulating in the machine to cool the surrounding air, so that the wind sent by the fan blade has a cold feeling. The industry calls it physical energy storage cooling. However, this cold air is very cold, but at best it is 3-5 ° C lower than the ambient temperature (at the air outlet), and if the air conditioner is full horsepower, the temperature at the air outlet is only 10-12 ° C, lower than the ambient temperature. 20 °C is not limited, so I hope that relying on the air-conditioning fan to maintain a constant and comfortable room temperature to bring a cool summer consumers, I am afraid there will be some disappointment.
Why are air-conditioning fans selling?
Can't realize the real sense of refrigeration, why is the air conditioner fan still hot?
Some engineers analyzed: "First of all, its price is more affinity. For ordinary Beijing citizens, it takes too much luxury to take out three or five thousand yuan to buy a "four-four-year free" air conditioner. Fans only sell for five or six hundred yuan, which can be said that everyone can afford the cool; secondly, although the air-conditioning fan can not achieve the true meaning of refrigeration, but it is much stronger than blowing the wind to heat the electric fan. For the elderly and patients who are unbearable to the "cold wind" of air-conditioning, the room temperature of the air-conditioning fan seems to be just right; thirdly, the air-conditioning fan is popular with the city. The Beijing is located in the North China Plain, and the summer is not very hot. Unbearable but relatively dry, and the air-conditioning fan can cool down three or five degrees and has a humidifying function, which seems to be tailor-made for Beijing. In addition, Beijing's old houses and bungalows are quite old, and old circuits are difficult to carry kW of air conditioners. The total input power of the air-conditioning fan is only 60W, and there will never be any troubles of tripping. For the migrant workers in Beijing, the air-conditioning fans that are not installed are also adapting to the life of the renters at any time; More impressive is the multi-purpose machine. According to research, as early as ten years ago, the air-conditioning fan was introduced to the mainland by Taiwan, but it was ugly and stupid in the past, except for the air blow, no trick, noisy (noise) It is also very large, so it is quite unnoticed, so it has been eliminated. It has already come back to the world, and many brands and many additional functions are dazzling. What kind of heating function is Fujibao, Lianchuang, Xinghui, Huagong, Huoliyang... (Winter can be used as electric heating), negative ion hair growth function, humidification function, etc. Some products are also equipped with ice trays beside the water injection port. After the ice cubes are placed, the cooling effect is more ideal. In addition, the remote control function is compared. Lazy Beijingers are also very tempting.
Shopping guide
1. It is necessary to see whether the manufacturer, address and telephone number of the goods are complete; check whether the three certificates are complete (certificate, warranty card, instruction manual); electrical products must have Great Wall Electrician safety signs, otherwise it is unqualified products. [1]
2. Whether the air volume at the air outlet is large enough, when standing at a distance of 3 meters, it should be able to feel the obvious air volume. [1]
3. If it is a cold and warm type air conditioner fan, it should be asked whether the heating material is a PTC semiconductor ceramic heating material. [1]
4. Check which type of cooling method is used. The first generation of air-conditioning fans is the rolling cooling of the curtains. Later, the spray-type water circulation technology has become the mainstream. This year, it is better to use the ice-crystal cold storage air-conditioning fans, so as to minimize the air temperature. [1]
5. If the air-conditioning fan has the function of negative ion oxygen bar and photocatalyst material, it can remove dust and filter and purify the indoor air, which is more in line with the requirements of health and environmental protection. [1]
add another point:
The so-called "air conditioning fan" only has the word "air conditioning" in the name, and has little to do with the adjustment of the air temperature. The air conditioner can reduce the temperature of the air in the room because it has the ability to "handle" the heat from the room through the heat exchanger, the pipeline and the refrigerant to the outside to smoothly adjust the air temperature in the room. However, the "air conditioning fan" does not have such a "handling" capability, it can only cause forced circulation of air through the motor and the fan blades like an ordinary electric fan. The rest of the so-called "cooling" refers to "adding water" or "adding ice", "reducing" the "air temperature" of the air outlet, as if it is capable of cooling, but it is not. The wind blows on the person's body. Because the evaporation of sweat will lower the surface temperature of the human body, it will make people feel cool. It will feel like cool when rubbed with water, but this feeling will not be maintained because the temperature is only Without falling, heat is inevitable. In summer, the air is stuffy, and an important factor is that not only the temperature of the air is high, but also the humidity of the air is high. Because of the high humidity of the air, the sweat on the person does not come out, and it feels "sweltering". The tightness of the air-conditioning fan is just right. It raises the humidity of the air that should have been lowered in the summer. It is like a humidifier, which acts just as a reaction. In summer, it can not only cool down, but it will make people feel sultry! As for the kind of ice, It’s even more ridiculous. I use the refrigerator to make ice. The refrigerator carries the heat from the water into the room. Then I put the ice in the so-called “air-conditioning fan†and let the ice go through the air. This is called “absorbed heat.†"Isn't it just the heat that is released when the refrigerator is cooled? It turns out that the scientific principle of energy conservation plays a role, and it can't be cooled, no matter what the advertisement says!"
Negative ion + gentle hair dryer, air conditioning fan is healthier
The concept of "health" in the air-conditioning industry has been transplanted into electric fans, and negative ion, oxygen bar, ultraviolet sterilization and other functions are common in the current mainstream air-conditioning fan products. The main working principle of the air-conditioning fan is to use the adsorption effect of the water cloth inside, and use the fan to blow out the water vapor to play the role of humidification and cooling. Therefore, the "health" function of the air-conditioning fan is reflected in the role of "blowing". The negative ion-equipped air-conditioning fan can use the built-in negative ion emitter to “blow†air into the negatively charged ions, thereby neutralizing the positively charged smoke and dust in the air, blocking bacteria, dusting and deodorizing. The function of purifying the air; the air-conditioning fan of the "oxygen bar" concept also increases the oxygen content in the air through a similar principle; the ultraviolet sterilization fan emits ultraviolet rays through the ultraviolet generator to kill the bacteria in the air, thereby improving the air quality.

From the adjustment of the air supply, whether it is a tower fan or an air-conditioning fan, the air can be supplied at a multi-angle through the loose-leaf sheet and the internal air supply system, and the air volume is mainly soft wind. This avoids the impact of excessive hair on human health, especially for those with weak constitution and middle-aged and old friends.
