1, dehumidifier to buy suitable for the area of their rooms: dehumidifying power is too small will make the dehumidifier shoulders too large, dehumidifying power is too strong and will consume excess electricity. So buy dehumidifiers do not greedy cheap buy dehumidification capacity is not enough, and do not use too good for small rooms, are based on the amount of dehumidification to calculate.
2, dehumidification capacity calculation formula is as follows:
The basic formula is to each square meter (a ping = 3.3 square meters) can dehumidify 0.24 liters per day calculation.
For example, the indoor area of 6 square meters: 3.3 × 6 × 0.24 = 4.8, you can purchase 5 liters capacity. It can also be simplified to a ratio of 1:1, such as 6 pings to buy 6 liters of capacity.
Basically, one ping is based on one liter of dehumidifying power. Consumption of one degree of electricity (KWH) can remove a number of liters of water from the air called energy factor. Choose the energy factor value greater than 1.00 (liters / degree) or more in line with the requirements of power saving.

1, usually dehumidifier in low humidity and low temperature (ring temperature <10 ℃ and humidity <45 ℃) when used under the conditions, dehumidification will be significantly reduced, or even no dehumidification, which are normal signs; usually the wetter the habitat, the greater the dehumidification capacity required.
2, pay attention to the operation of the dehumidifier sound: consumers need to first to the store or market place to experience themselves against the reality, but because the store sometimes leaning sound is very loud, may not hear too much to the mechanical operation sound, I suggest touching to feel the mechanical operation of the sense of shock, theoretically the more serious the shock will also be the more high sound.
3, remember the relationship between the dehumidifier and dehumidification temperature: usually compressor type dehumidifier due to the principle of cold air machine, compressor type dehumidifier is divided into A type dehumidifier and B type dehumidifier, A type dehumidifier dehumidification temperature limit in 15 ~ 35 degrees, while B type dehumidifier is between 5 ~ 35 degrees, so the colder the weather dehumidification force will be lower, which is a normal sign.
The principle of dehumidifier
1, the manufacture of dehumidifier runner is more than 500 ℃ temperature-resistant ceramic fiber paper, through the molding machine made of honeycomb-shaped runner, and then coated with silica gel in between the ceramic fiber and get, so dehumidifier runner will not occur burning and dampness and other problems. As its dehumidification effect is the exercise of physical action, rather than chemical action, so there will not be any harmful chemicals.
2, the dehumidification principle of the rotor type dehumidifier is the exercise of silica gel coated on the rotor to adsorb the water in the air in a physical way with porous synthetic silica gel, and then in the regeneration area of the rotor, the water adsorbed in the pores of the silica gel will be heated and vaporized to the entrance of the AC type heat exchanger to form high temperature and high humidity air, and then through the heat exchanger that has been cooled and cooled by the cold wet indoor air, due to the difference in dew point and Cohesive water is discharged.
