In order to obtain dry air, people turn to the home appliance market in recent years new - dehumidifier. Reporter survey found that such products related local spot check situation is not optimistic, at the same time as a kind of air conditioning appliances, dehumidifier has begun to "pluralism". To this, the expert points out, should be rational treat dehumidifier function.
Dehumidifier into homes
"The house is too wet, lying in bed feel sheet as on the shop before dry, very uncomfortable." Garden bridge in Beijing, gome stores, consumer ms fang says, her family lived a layer, humidity is big, at ordinary times much rain in Beijing this summer, the room is wetter, sheet bedding feels ChaoHuHu, also have signs of mould on the wall. She felt the dehumidification function of air conditioning effect is limited, so going to buy a dehumidifier.
Consumer mr.chen told reporters that he have a passion for calligraphy and painting collection at ordinary times, home there are quite a few pieces, one to this wet weather will have some worry, so just in the online bought a dehumidifier.
Consumer Mr Huang has admitted, he buy dehumidifier is entirely for the sake of your family's health. Old people waist is bad, children less than one year old, poor ability to adapt to bad weather.
Hangzhou wet, dehumidifier, head of the production enterprises, told reporters that in recent years, both the south and the north, and wet weather is more and more intensive, consumers become more and more high to the requirement of the quality of life, so the dehumidifier in the domestic sales rise year by year. In May 2015, the company of the dehumidifier sales than in April increased by thirty percent, increased by 15% than the same period last year. In addition, every year the south dehumidifier market started much earlier than the north, such as in guangdong area, generally one into three in April, dehumidifier sales began to enter the peak season.
Gome said promoters at Beijing garden bridge, the unbearable hot and humid season in Beijing at most two or three months, and auxiliary dehumidification air conditioning, so in Beijing, dehumidifier sales co., LTD. But overall, the two years of sales or gradually increase. He believes that in addition to related people to ascend to the requirement of the quality of life, but also has much to do and people living conditions improved, after all, this kind of product in the home will have a long idle time, takes up a larger storage space.
Reporter found in taobao search, the role of home dehumidifier field is becoming more and more differentiation, many cottages are played a dehumidifier dehumidification banner. Part of this small products on special space, such as chest, bookcase. Recently in quite a few shops volume achieves hundreds, or even up to thousands of machines.
Product quality good and bad are intermingled
What brand of dehumidifier? "" Ms fang confused mentioned above. The reporter also found in web search, the problem with universality in the consumer, many consumer in "baidu knows" and other similar problems to the BBS. Journalists access to relevant information, found that in recent years, national and local authorities for dehumidifier quality spot check is not much, but a limited number of times the results are not optimistic.
Such as the 2007 national spot check dehumidifier percent of pass is 87.5%. In early 2012, commissioned by industrial and commercial bureau, guangdong province, guangzhou wei kai testing technology research institute in the special monitoring of dehumidifier commodities, were in zhuhai, meizhou city, zhongshan city three areas examined, 10 10 brand dehumidifier, six product is not qualified as a whole. Among them, the dehumidification performance project - "capacity" and "unit input power capacity" issues such as the most outstanding.
The relevant person in charge of guangdong province said that the water condensation rate is the most important parameters that reflect the dehumidifier using effect, the water condensation rate, the greater the dehumidifying effect of the product, the better. Check in, a total of 5 product is not qualified in this project. Investigate its reason, mainly is the enterprise did not according to the actual product quantity of desiccant dehumidification performance stated, measured the water condensation rate less than 95% of the explicit value, the more 3 product is measured the water condensation rate less than 60% of the express values; Capacity unit input power is reflected dehumidifier products are the key indicators of energy efficiency, refers to the standard stipulated in the name of the working conditions, the water condensation rate and the ratio of total power input. The index is larger, the higher the efficiency of dehumidifier. The project is not the main reason for the qualified on the one hand is due to the unreasonable product structure design, on the other hand is poor due to the use of components and materials. Some enterprises in order to save the production cost, compressor, motor, base and does not use high efficiency and energy saving heat exchanger; A part of the product to reduce cost, use small heat exchanger, seriously affecting the effects of moisture.
Shanghai of secretary-general of guild of commerce of electric home appliances, said although the dehumidifier is not a new product, but before production is mainly used for export, the domestic market, especially the console market has just opened, the market on a smaller scale, industry lack of a strong brand, market is in disorder, basic product good and evil people mixed up, the rights and interests of consumers is difficult to secure.
According to the personage inside course of study introduces, many small businesses to reduce cost and obtain higher profit and use unqualified material. Also some small and medium-sized enterprises do not have their own research and development capabilities, and are eager to develop new products to expand the market, so the simple imitation of big companies, product appearance, hard to ensure the quality of the products.
Part-time function has often been questioned
Made haze has attracted unprecedented attention to air quality. Not only air purification products sell like hot cakes, air purification function can also be added on all kinds of air conditioning products. To this end, the dehumidifier enterprises also have launched purifying air dehumidifier, the nuggets air purification market.
Reporter saw a dehumidifier notes marked "increase anion and light catalytic function, make up for the deficiency of the traditional products only dehumidification purification, at the same time of dehumidification, sterilization, filtering, the fresh air through the photolysis purification ambient air, removal of formaldehyde and other harmful substances to human body". Some product is promoting its silver ions filter, "there is strong air purification function"; Have claimed that the titanium products, "can eliminate almost all of the harmful gas, mold and bacteria". More product claims can release far infrared ray and dehumidification of physical therapy efficacy can be achieved at the same time...
China institute of basic research center director, according to the working principle of dehumidifier is very similar to the air conditioning, so these products also meet for a 3 c certification standards, the new "the safety of household and similar electrical heat pump, air conditioner and dehumidifier the special requirements of" launched on May 1 this year. But this is for the quality of the product safety certification, and the performance of the dehumidifier and energy efficiency standards at present has not yet been released. For products in addition to bacteria, purify air, and other functions, while 2009 "household and similar electrical function of antibacterial, antibacterial, purifying the general rule has been started, and then released the washing machines, air conditioners, refrigerators, and the special requirements of air purifier, but for the anti-bacterial performance of the dehumidifier have no corresponding standard.
Businessmen in the commercial business, try their best to to the packaging of products, according to consumer attention hot spot making function concept. But in fact, some consumers don't need too many auxiliary functions. But for dehumidifier this kind of product, the consumer is not enough to understand, because of the small industry scale, at the same time, inadequate competition, industry low transparency, coupled with the lack of related standards, etc., it is difficult to let the industry regulations, is easy to appear the phenomenon of false advertising.
Expert proposal, don't be too fancy buy dehumidifier auxiliary functions. If consumers want to buy dehumidifier in wet at the same time, can purify air, might as well ask when buying the sales promotion personnel present related testing data.
8 note of choose and buy
1. The dehumidifier products belong to national compulsory certification, products should be 3 c compulsory certification marks.
2. Choose appearance is beautiful and easy, evaporator, condenser, fin order, uniform clearance, there is no "collapsed" phenomenon, plastic good brightness, high level of manufacturing products.
3. Check whether the marking the noise value. Noise value generally marked on the product nameplate or product specification, the smaller noise value said product, the more quiet. In addition, also can use hand feel the vibration of the machine, compressor type dehumidifying the opportunity to have the voice of the compressor is running, but the stores sometimes background noise is very big, could not hear machine noise, vibration theoretically the sound of the more severe will be the greater.
4. Pay attention to product energy efficiency. Usually dehumidifying the greater the amount of the product is, the greater the power capacity unit input power is reflected the key indicators of dehumidifier product energy efficiency. In order to prevent the qi of the enterprise, consumer should choose well-known brand products.
5. Buy dehumidifying ability to match your room size products. Dehumidifier, dehumidifier (l) according to the room area is 1 to 1.5 times the choice can meet the requirement of dehumidification.
6. According to the living environment of choose and buy. Dehumidification is not very big, if living area air wet enough, dehumidifier cannot achieve the result of claim. Preferably in accordance with the area of wetting degree. Where the more humid, dehumidifying ability stronger.
7. Had better choose to have humidity control products.
8. Try to buy function of a single product. Which has the function of the clean air dehumidification machine price is high, not only must also change regular filter, will increase the cost of additional.
Using 5 points
1. In general, dehumidifier should be centered place more appropriate, keep enough space around, dehumidifier and tuyere can not have obstructions, to keep the air clear.
2. In use shall not be forcibly pull the power cord to move the dehumidifier dehumidifier.
3. The use of dehumidification machine, the room is better in sealing, otherwise, the dehumidifying effect is not obvious, and it will increase the load of dehumidifier, affect the service life of the dehumidifier.
4. Dehumidifier are mostly on the market at present is equipped with computer automatic control system, there are four fuzzy control range, in addition to shut down a block, a suitable humidity (relative humidity: 70% 60%), dry (relative humidity: 60% 50%) and continuous dehumidification (minimum relative humidity: 35%), when the indoor humidity is higher than the corresponding choice humidity range above, the machines to start the desiccant; When the water tank in the inland waters full machine automatically stop working, and water level indicator to remind the tank is full, shall pour out the water to the machine works.
5. When he has to carry the body, should unplug the power cord plug, then in the inland waters pour out the water tank. Dehumidifier after a move is a good idea to let stand four to six hours before operation. Because of refrigerant is contained in dehumidifier compressor piping, after moving, refrigerant must pass through a period of time to return to in situ.
