There are many rains in the north this year, and household dehumidifiers are also beginning to be favored by northern consumers. In a number of shopping malls in Dalian, dehumidifier counters have been set up this year, and sales are optimistic. However, the reporter's investigation found that many consumers are not very familiar with the function and usage of the dehumidifier, and it is very easy to enter the misunderstanding of purchase and use. To this end, experts remind consumers to know more about the functions and methods of dehumidifiers when purchasing dehumidifiers, and avoid blind purchases.

Mr. Zhang, a consumer in Dalian, lives near Zhongnan Road, less than 300 meters from the seaside. Recently, the continuous rain, the wall and floor of the home began to return to the tide. He told reporters that in the past 15 days, the number of days in which his family's humidity reached more than 90% was 12 days. Because of the excessive humidity, his 5-year-old child had eczema under his neck and at the base of his thigh. The clothes were not dry for several days. In order to reduce indoor humidity, he purchased a dehumidifier. Mr. Zhang told reporters that when he left the door in the morning, he closed the window and opened the dehumidifier. When I went home at 6 o'clock in the evening, I found that the 5 liter drain box in the dehumidifier had overflowed with water.

For the principle of working on the dehumidifier, the staff of an electrical appliance store said: "The humid air is sucked by the fan of the dehumidifier, filtered by the air filter, and then cooled on the cooled evaporator, and the moisture of the air is condensed into water. Therefore, the water content in the air will be reduced. At the same time, since the dehumidified condensed water takes away a part of the damp heat, the temperature of the air is lowered accordingly. In order to make the air temperature suitable, the dehumidifier's unique structure allows the dehumidified air to pass through. The condenser is heated and heated to increase the ambient temperature, which greatly enhances the dehumidification effect of the dehumidifier."

On August 4th, the reporter saw in several stores in Dalian that the style and types of dehumidifiers are not much. The height of each dehumidifier is only about 40-50 cm, and the area is not large. However, the price of each such "little guy" can be compared with that of the refrigerator. The lowest price is also 1980 yuan. The highest price broke through 3,000 yuan.

According to the reporter's understanding, a dehumidifier can generally drive an area of ​​15 square meters, which can drive an area of ​​30 to 40 square meters. Wang Guosheng, an engineer of the Consumer Electronics Association of Dalian Consumers Association, said that it is enough for a family to buy one, but if a dehumidifier is placed in the living room and a dehumidifier is placed in the bedroom, the effect is more obvious.

●Expert reminder

When consumers purchase dehumidifiers, they need to purchase them according to their own needs. There are several common mistakes that need attention.

Misunderstanding 1: The air conditioner is a dehumidifier. Some air conditioners have the function of dehumidification, but the dehumidification amount is small, the dehumidification range is small, the dehumidification is slow, and the air blown by the air conditioner is cold air, and the more dehumidification is colder, which affects the indoor temperature. The principle of the dehumidifier is to convert the excess water in the air into water droplets, which are then collected into the water tank inside. During the heat exchange process, the temperature change is not too great.

Misunderstanding 2: Dehumidifier is a purifier. As people pay more and more attention to indoor air quality, dehumidifiers have also started to play health cards. Many dehumidifiers on the market are marked with functions such as negative ions and oxygen bars. Experts suggest that you should first look at the main functions when purchasing, and don't pay too much attention to additional functions.

Misunderstanding 3: The greater the dehumidification ability, the better. In fact, if you choose a larger dehumidifier, it will not only occupy a place, but also high power will result in high power consumption. If the area to be dehumidified is relatively large, the dehumidification time is slightly longer, and the desired effect can be achieved. Reporter Zhang Heng
