Yesterday, I saw a message from a netizen in the comment area of the dehumidifier evaluation article, thinking that we should publish an article about Dehumidifier knowledge. It just happened that this week's topic selection was a little lacking. Thank you for the enlightening role played by this netizen. Here should be applause~
What is the use of Dehumidifier abroad
Preface: The survey data shows that the penetration rate of Dehumidifier in Europe, America and other developed countries has reached more than 30%, South Korea 29%, Japan 28% and China 2.4%; Taiwan, China, China 68%, Hong Kong, China 55%, while mainland China only 1%. In 2015, 286 cities in North China, East China, South China and other regions had more than 130 days of rainfall throughout the year, and Dehumidifier became the first choice for many families to cope with humid environments
There are two different voices in the industry about the future prospects of China's Dehumidifier industry. Optimists believe that Chinese residents spend more than 20 hours working, studying and living indoors every day, accounting for more than 80% of the whole day. The indoor air humidity has a far more important impact on the human body than the outdoor air. Generally, the indoor air humidity is circulated by using Whole-house fan or opening windows. However, facing frequent plum rain weather, it is impossible to reduce the humidity of indoor air. Due to the development of the economy and the improvement of people's quality of life, the prospects are worthy of recognition. In the next few years, the popularity of Dehumidifier in Chinese families will be the same as that of household air conditioners. The commercial aspect will also make great progress, and the rapid development in recent years is a good proof However, conservatives believe that the prospects are relatively optimistic. There are mainly four aspects. First, consumers are not aware of consumption and have a wide tolerance range for the humidity of air conditioners. Generally, only 2-3 months in a year belong to the Korean period, and most consumers take the way of enduring it. In addition, the dehumidification function of air conditioners is easy to make consumers regard Dehumidifier as household appliances to add to the beauty; Second, the consumption level is limited. The principle of Dehumidifier is similar to that of air conditioners and the cost of materials used is also similar. Taking Deye Dehumidifier as an example, the cost of a 20L/D Dehumidifier is equivalent to one air conditioner. In addition, due to the small market demand, it is difficult to form a scale advantage in production, which leads to the price being similar to that of air conditioners, which is difficult for consumers to accept; Third, insufficient publicity. At present, household dehumidifier are generally sold naturally, and manufacturers usually do not have sales promoters. The publicity of Dehumidifier is also very weak, resulting in serious information gap between producers and consumers; Fourth, the competition is fierce. With the technical disclosure of Dehumidifier products, the threshold for entering the Dehumidifier industry is gradually lowered, and more and more household appliance enterprises are beginning to enter the Dehumidifier industry. The profit of its products has been very transparent. If more big brands and enterprises participate in this market in the future, it will be difficult for the inferior brands to have Lebensraum. At that time, this market will be reshuffled
Some people say that dehumidification by air conditioner is also possible. Why use a Dehumidifier
Air conditioners are not equal to Dehumidifier. Although they all use the principle of refrigeration, there are essential differences between the two
Because the air conditioner can be used in summer with a little dehumidification function, and it can also make people feel dry indoors when heating in winter, many consumers mistakenly believe that the air conditioner can also dehumidify. So which is better, the air conditioner or the Dehumidifier? At present, the impact of humidity on the indoor environment has attracted the attention of some people, many of whom use air conditioners for dehumidification. However, this does not fundamentally address the impact of excessive humidity
First of all, from the perspective of dehumidification efficiency, the dehumidification capacity of the air conditioner is only about 30% of that of the Dehumidifier, while the power consumption is five times that of the latter. Long term use will also damage the compressor and shorten the service life of the machine. This is because both air conditioners and Dehumidifier use the principle of heat exchange. The heat exchange of air conditioners is mainly used for refrigeration and heating. In refrigeration, because the indoor humidity is reduced, the indoor dew point is reduced, so it will have a slightly dehumidification function. Unlike air conditioners, the heat exchange of Dehumidifier is all used for dehumidification, without other energy consumption, so the Dehumidifier is more professional and efficient in dehumidification and moisture-proof
On the other hand, air conditioning cannot be controlled based on indoor humidity. If dehumidification occurs, the refrigeration mode must be continuously operated.
. The Dehumidifier is automatically controlled according to the indoor humidity. When the user's requirements are met, the machine will automatically enter the standby state, so it is more energy-saving than the air conditioner. The machine does not need to be left on for a long time and has a longer service lifeSecondly, air conditioning is generally fixed in living rooms, bedrooms, and other rooms, and the dehumidification effect is not significant for corners such as bathrooms and kitchens with high humidity.
. The Dehumidifier adopts a mobile mode, which is small in size and equipped with a universal wheel on the sole of the foot. It is convenient to move. It can help wherever it is wet, and there is no dead space left for dehumidification and moisture-proof
In addition, air conditioning dehumidification also has certain requirements for temperature. Below 20 ° C, the lower the room temperature, the worse the effect. However, the enabling of air conditioning can only make the room temperature lower and lower, which is of little help to some southern regions that are currently in the rainy season and have relatively low temperatures.
. The Dehumidifier, on the other hand, is not affected by the indoor temperature and will not increase or decrease the indoor temperature. It can be used repeatedly for a long time
About the purchasing skills of Dehumidifier, how to match the housing area with the Dehumidifier specifications
Each humidifier has its own applicable area. This parameter is greater than or equal to the area of your room. I checked it when I bought it before. It can be estimated that the dehumidification capacity is divided by 0.6, for example, the applicable area of a 12L/D Dehumidifier is 20 square meters I have a detailed applicable area comparison table from Japan. However, this dehumidification capacity is based on Japanese standards and needs to be divided by 0.6 to roughly match the standards of domestic manufacturers. Because there are very few wooden residences in China, the last two columns of data (the middle column is the applicable area for a single room, and the right column is the applicable area for a suite) are relatively more informative
It can provide stable dehumidification efficiency in different seasons and is not affected by environmental temperature (1 ℃~40 ℃). At the same time as efficient dehumidification, the rapid release of dry air disrupts the humid environment on which bacteria rely for survival. It also helps to suppress the growth of bacterial count in indoor air and balance the effectiveness of clean air, helping to absorb PM2.5 particles in the air
It can be said that once you get one, dehumidification, drying, antibacterial, and purification are all done!
Editor's summary: The research shows that when the relative humidity in the environment is greater than 60% RH, the human body's physical comfort will be reduced, resulting in lethargy and depression. Living in such an environment for a long time, the human body's immunity will be greatly reduced, and it is very easy to suffer from skin and respiratory diseases such as wet, Rheumatoid arthritis, eczema, which brings many inconvenience to life. In addition, metal products, electrical appliances, high-precision equipment, food, medicine, home furnishings, leather goods, and precious collectibles in the home will all be vulnerable to the threat of mold, causing incalculable economic losses. Therefore, it is very necessary to make rational use of Dehumidifier to reduce air humidity for us
