How to choose household dehumidifier
4hw.com.cn: in humid areas, you will want to buy a dehumidifier to remove the humid indoor air. But how to buy a dehumidifier? Many people don't know how to choose it. What to do if the one you buy is not suitable for you. Editor today from several aspects to recommend dehumidifier.
Selection of household dehumidifier
Look at the brand
We are buying dehumidifier not only depends on the price, but also depends on the brand. What about brand? We can consider the origin, establishment time and after-sales service of the brand. Generally, international brands have stronger technical advantages and higher prices. Dehumidifiers of international brands in Europe and America have high dehumidification capacity, while dehumidifiers of Japan and South Korea have a variety of small functions. There is no obvious boundary between domestic brands in terms of function, and there is little difference in function. If you want to recommend it, Panasonic, Delong, sharp, oujing and other properties are not bad. Therefore, when consumers purchase dehumidifiers, they should try to choose brand dehumidifiers at the same price. The products and after-sales service are relatively guaranteed.
Choose dehumidifier according to room size
Generally, the instructions on the dehumidifier will clearly mark the daily dehumidification capacity and applicable area, which can be purchased according to the actual situation. Don't buy a dehumidifier with insufficient dehumidification capacity for less money, which will increase the load of dehumidifier, and the dehumidification effect is not good. If you buy a dehumidifier with large dehumidification capacity, and the room is too small, it will also consume electricity.
Selection of air outlet position of dehumidifier
The dehumidifier with the air outlet above can generally adjust the angle of the air outlet, so as to better control the air outlet range, and can also use the dehumidifier as a clothes dryer. For families with large areas, you can choose larger ones. Generally, the air outlets are set on the front panel, so that the area of the air outlets is large, the range of dehumidification is wide, and they can also be used to dry clothes.
Power consumption of dehumidifier
Attention should be paid to the power consumption in the use of dehumidifier. The stronger the dehumidifier, the greater the power. At present, dehumidifiers are divided into 'compressor' and 'desiccant'. In terms of power consumption, the 'desiccant' dehumidifier consumes more electricity than the 'compressor'. "Desiccant" dehumidifier, because of the need to heat the desiccant, the heater will also consume electricity. The power of dry dehumidifier is about twice higher than that of compression dehumidifier.
Noise problems
If you put the dehumidifier in your bedroom and want to use it more at night, you should choose the dehumidifier with low noise. For families with babies and the elderly, their sleep is relatively clear, easy to wake up, not easy to fall asleep. Be sure to choose low noise products, which can minimize the disturbance to sleep or life, even if it is used all night.
So how much noise is lower is more appropriate. The basic standard of environmental noise is the basic basis for the establishment of environmental noise standard. Most countries refer to the base recommended by ISO (for example, the higher sleep standard is 30 decibels). If the decibels of noise are lower than 30 decibels or between 30 and 40, it means the noise is lower.
Choice of washing
If you use dehumidifier in the bedroom, living room, study and other inconvenient rooms with direct drainage, the water tank can be as large as possible to avoid frequent back and forth water pouring. Dehumidifiers are equipped with water full shutdown settings. If the water tank is too small and the building area is relatively large, the dehumidifier will soon be full of water and stop working when there is no one.
The water tank capacity is generally between 2L and 9L. The water tank adopts drawer type and handle type. If the scope of the home is large and the area is very wet, you can choose the water tank capacity of about 8L. If a large capacity water tank is selected, it is recommended to use a water tank with a handle to facilitate water pouring.
Select dehumidifier with humidity setting
When the temperature is between 15-18 ℃, the best humidity is between 40% - 60%. When the humidity is about 55%, the germs are difficult to spread. When the temperature and humidity are lower or higher than this range, people will be uncomfortable.
Some low-end dehumidifiers generally can't set humidity. This dehumidifier generally stops working only when the water tank is full. This dehumidifier sometimes leads to excessive dehumidification, and the humidity in the room will be lower than the comfortable humidity of human body.
Therefore, the dehumidifier that can set its own humidity shall be selected. When the humidity reaches the set humidity, the dehumidifier shall be shut down for operation, so as to save energy and be more comfortable.
Pay attention to the dehumidification capacity format of dehumidifier
Dehumidification capacity is the capacity to remove water from the air. The common dehumidification units are L / D (liter / day) and L / h (liter / hour). Pay attention to the units when purchasing. There is a big difference between the dehumidification capacity of one day and that of one hour.
Proper operation mode
Dehumidifier buttons are common mechanical keys and light touch keys, both of which have their own advantages and disadvantages. When purchasing, you can choose the appropriate style.
The dehumidifier with mechanical button has a single function. Generally, it only has dehumidification function. It will adopt the form of rotary button, with only 2-3 gears. The mechanical button has the advantages of clear operation, simple and convenient operation, suitable for the elderly.
The dehumidifier with the light touch button has more functions than the mechanical button, such as dry clothes, wind speed, timing, set temperature, anion, etc. these functions can be operated with one button, which is very suitable for young people.
The operation interface can also display the operation status of the machine, such as the water full status. The light touch button is generally matched with the LED liquid crystal display, which can display the set humidity at a glance. So it's better to buy only the dehumidifier that suits you.
