At present, the domestic market of dehumidifiers is still immature, and the quality of dehumidifiers on the market is uneven, so it is hard to buy a good one! How can I buy a dehumidifier that is both practical and elegant? The following is how to read the parameters of dehumidifier. Welcome to read it. I hope you will like it.
At present, many small domestic manufacturers will mislead customers and consumers, and the package of dehumidifier says (35 degrees Celsius and 9 humidity), which means that the dehumidification capacity is very large at 35 degrees Celsius and 9 humidity. In this environment, the weather is hot and the humidity is high. Of course, the amount of water pumped will be a little larger, but this weather situation is rare, so this writing does not represent how strong the performance of the dehumidifier is.
If you see the page of dehumidifier marked (3 degrees Celsius, 8 humidity), it is the humidity in the general rainy season and rainy season. Only when such test conditions are clearly stated can the practical value of dehumidifier be explained.
2. Key parameter: power
Although the higher the power, the better the dehumidification effect may not be, but the lower the power, the better the dehumidification effect will be. But now many unscrupulous merchants will make a fuss about power, often using maximum power to replace working power. Anyone who has studied physics knows that the maximum power of electrical appliances will only exist in a few seconds after starting, which has no reference significance. Therefore, the reference of power is best to use the average working power as a reference.
3. Key parameter: noise
For the convenience of consumers, most dehumidifiers on the market today are made of plastic. However, due to the thin plastic shell, the dehumidifier is likely to cause * * * vibration during operation. If there is * * * vibration, there is a problem in the adjustment or assembly of system parameters in the dehumidifier, and the service life of this machine will be very short.
Many consumers are buying dehumidifiers for the first time. Without comparison, they naturally don't know that the sound of dehumidifiers can be very light. With the silent design of water tank dripping, the dehumidifier can reduce the noise value of the product to the lowest (below 46dB), increase the service life of the machine, and will not affect sleep.
4. Key parameters: Safety
The fire box of the internal circuit of dehumidifier is not a mandatory specification, but for the OEM of Japanese and Korean brands in China, there are mandatory requirements for the fire box in the internal specifications, and most mature foreign dehumidifier brands have fire box design requirements to avoid fire hazards caused by large current and electric sparks. There is also an evaporator. The more copper pipes and metal fins are used, the heavier the fuselage will naturally be. In addition, good compressors, motors and ABS engineering plastics are also significantly different from low-end products in weight, which are important references to distinguish the quality of dehumidifiers.
5. Other aspects:
In China, dehumidifier is still a relatively novel environmental appliance, so users often don't know where to start when facing a dehumidifier. In fact, at first glance, the quality of products can be reflected in the appearance design, detailed workmanship and weight of materials. In terms of appearance, well-crafted products with a sense of design often come from the hands of masters and manufacturers, which is more trustworthy; Details, button touch, functional layout, fuselage gap, caster water tank, products that are handy and comfortable to touch are better used; In terms of weight, machines of the same standard, the better the materials, the more weighty they are. If you compare them, you will know whether to cut corners.

how to select dehumidifiers
1. brand selection
(1) ccc certified products
home dehumidifier is a compulsory certified commodity (CCC certification), which is an important standard to ensure the safety of use. We must recognize this logo when buying home dehumidifier, which is the first and one of the most important steps in buying home dehumidifier. CCC logo of dehumidifier, the main parameters and real manufacturer of dehumidifier can be found through CCC certification number on the general website of national quality inspection. In the market, dehumidifiers that have not passed CCC certification are not allowed to be sold.
(2) Choosing products of famous brands
Brands are directly related to the quality of products, and the consequences of inferior products are unimaginable. The manufacturers of well-known brand dehumidifiers have a complete set of perfect quality management system, which has good product quality assurance ability, and their products have certain guarantees in performance and safety. In addition, home dehumidifier is generally a durable consumer product, and consumers need manufacturers to provide after-sales service to inspect, repair or replace parts when there is a failure during use. And some brand-name manufacturers only care about selling products, without after-sales commitment, the rights and interests of consumers can not be guaranteed.
(3) Choose a brand with good after-sales service
The brand, quality and service of dehumidifiers are important reference factors when buying dehumidifiers. Now, the quality of domestic brands is similar, and the most important thing is service. It is necessary to choose a dehumidifier brand or merchant with perfect after-sales service. In addition, we should try our best to choose the dehumidifier manufacturer or merchant who delivers the dehumidifier to the door, because the dehumidifier can't be placed upside down and horizontally. Professional dehumidifiers can also learn more about the use knowledge of the dehumidifier when they come to the door, which is convenient for us to operate and use the dehumidifier correctly and make the dehumidifier perform its best.
(4) You should choose the merchants who have regular channels to purchase
home dehumidifier has been a very popular small household appliances abroad, but it has not been accepted by the majority of home users at home, so there are not many manufacturers. At present, in addition to imported brands, several well-known brand manufacturers in home dehumidifier are producing them, and there are not many imitations and counterfeits. But even so, it is still recommended that you go to large-scale home appliance sales malls or brand stores to buy dehumidifier products from well-known manufacturers. If you choose online shopping, you can choose well-known online shopping malls to buy them through price comparison, so that future repairs and maintenance are more guaranteed.
2. Matching of dehumidification capacity
Of course, the main function of home dehumidifier is to dehumidify indoors, and dehumidification capacity is the most important parameter reflecting the use effect of dehumidifier. The greater the amount of dehumidification, the better the dehumidification effect. However, just like doing anything, buying a dehumidifier needs to be tailored. If the dehumidification capacity is too small, the dehumidifier will be overburdened, and if the dehumidification capacity is too strong, it will consume more electricity. Therefore, don't buy a dehumidifier with insufficient dehumidification capacity, and don't use a good dehumidifier in a small room. Everything will be bought according to demand.
(1) Consider the size of the space used
Generally speaking, the home dehumidifier is selected according to the actual maximum space area of the family (such as the living room). For example, the living room is the largest area in the family, with an area of 4 square meters and a height of 2.8 meters. It is the best configuration to buy home dehumidifier with a dehumidifying capacity of about 4 liters. Usually, one square meter of space is calculated according to one liter of dehumidifier. It should be noted that if the height is more than 3 meters, it is necessary to increase the configuration of dehumidifier to meet the needs of space moisture prevention. The standard dehumidifying capacity of dehumidifier refers to the environment in standard temperature and pressure (the effluent volume measured at 3℃ and 8% humidity). The doors and windows of the room that needs dehumidification must be closed tightly, and the dehumidifier is better in a well-sealed space.
(2) Considering the humidity of the surrounding environment
The greater the dehumidification capacity, the better. If the air in the residential area is not humid enough, the dehumidifier cannot achieve the claimed effect. It is suggested that the dehumidifier should be selected according to the humidity and space size of the residential area. The wetter the residence, the greater the number of dehumidification capacity. If you live in a very humid area and often feel that the floor is wet or there are water droplets on the ceiling, you can choose a model with strong dehumidification ability, all depending on your own needs.
(3) Considering the characteristics of the place of use
Choosing the amount of dehumidification in home dehumidifier should also consider the characteristics of the place where the dehumidifier is used. For example, our home is made of many solid wood products and leather products, so we need to consider the performance of the dehumidifier to dehumidify and control humidity in the whole space within 3 to 5 hours in the south wind, so as to avoid the moldy expansion of wood products and the reduction of the service life of leather products.
3. Selection of functions
(1) The main function of dehumidifier is to reduce humidity and inhibit the growth of mold, so dehumidifier with purification and sterilization functions and drying clothes is very suitable for home use.
(2) When choosing a home air dehumidifier, we need to determine who will use the dehumidifier we bought. If it is used by some young people, we can consider using some dehumidifiers with complex functions and multi-layer design. If it is mainly used by the elderly or children, it is recommended to choose some mechanical dehumidifiers with one-button start or electronic control dehumidifiers with automatic key design.
(3) according to the control of time, if the home is unattended for a long time, you should buy a fully automatic dehumidifier with a slightly larger built-in water tank or choose to buy a dehumidifier with an external drainage interface, and you only need to connect another water pipe to realize long-term unattended.
(4) For a household appliance with a clear purpose, products with relatively single functions often have higher cost performance. Therefore, don't be too obsessed with the promotion and introduction of other functions by merchants. You should know that some impractical functions will not only increase your purchase cost and use cost, but even make future repairs and maintenance more troublesome, which is not worth it.
4. Consider the noise of the dehumidifier
Generally speaking, the compressor-type dehumidifier will have the sound of the compressor running, especially the early products. Although it has been greatly improved and the noise has been reduced, we still need to consider the operating noise of the dehumidifier when purchasing home dehumidifier. For example, if it is used in bedrooms, study rooms and other rooms, it needs to be able to maintain a quiet environment and have a strong dehumidification effect, especially for the elderly, children and people who are sensitive to noise at home. We must pay attention to choosing products with low noise.
when we buy home dehumidifier, we can judge this performance of the machine through trial operation. However, we should pay attention to one thing when judging: it is best to find a relatively quiet space for testing, because the family environment is much quieter than the store.
5. Regarding the appearance and others
(1) When choosing home dehumidifier, we have to consider whether the appearance design of the machine is beautiful and generous, and the most important thing is whether it is convenient for us to clean. Before, many domestic dehumidifiers used designs such as full grid, and later cleaning and maintenance was a big problem. Everyone always didn't want to live with a dirty dehumidifier every day.
(2) The price of dehumidifier is believed to be the most important purchase reference factor for many families. Need to remind everyone that blindly pursuing low prices is also an irrational way of buying, and it is easy to buy inferior goods. In addition, dehumidifier products with lower prices can be purchased online.
6. Choose a small space of
2-3 square meters according to the space area
Because the space with an area of 2-3 square meters is small, the dehumidification capacity of the dehumidifier does not need to be too large. If the dehumidification capacity is too large, it will lead to indoor drying. Therefore, a dehumidifier of 1-15L/ day (L/DAY, 3℃RH8%) can be selected for a space of 2-3 square meters. This dehumidifier consumes about 2W, which is more energy-saving and durable.
3-45 square meters of space
For a home with a general area of about 1 square meters, the living room area accounts for about 3-4 square meters, and a dehumidifier with a dehumidification capacity of 2L/ day is generally used for this area of space. The power consumption of a dehumidifier (L/DAY, 3℃RH8%) with a dehumidification capacity of 16-2L/ day is about 2W~25W per hour.
5-6 square meters of space
4-5 square meters of space are generally mostly in large-sized homes with an area of about 15 square meters. The space of 4-5 square meters is not too big, but it is not too small. If you want to have strong moisture absorption capacity, then the dehumidifier with a capacity of 26-3L/ day can meet the demand occasionally. Its power consumption is about 45W~55W per hour.
a space of more than 8 square meters
a space of more than 1 square meters generally appears in villas with hundreds of square meters. Generally, villas will use multiple dehumidifiers for dehumidification. If only one dehumidifier is used in the space, dehumidifiers with a dehumidification capacity of more than 3L/ day can meet the demand. According to the dehumidification capacity of dehumidifiers, they can be placed in different corners of the space for targeted dehumidification. Generally, the power consumption of a dehumidifier with a dehumidification capacity of 3L/ day is 33W~38W per hour.
