Dehumidification portion 230 can adjust the humidity from outside leaked-in air.
Specifically, from outside leaked-in air described in can cooling down, so as to reduce the saturation water that the air can include
Vapor volume, now, when more than the saturated steam amount, Water vapor condensation is water, such that it is able to reduce what air included
Steam vapour amount, that is, reduce humidity.
In one embodiment, dehumidification portion 230 is using compressor 231, condenser 232 and heat exchanger 233 guiding refrigerant gas
Phase change, and using the endothermic reaction that causes of phase change of refrigerant gas, dehydrating unit 200 is flowed into such that it is able to cool down
Air.
That is, when compressor 231 compresses refrigerant gas, condenser 232 makes the refrigerant gas of above-mentioned compression liquefy, the liquefaction
Refrigerant gas the air of surrounding can be cooled down while gasify in heat exchanger 233, expand.Afterwards, the refrigerant gas
Compressor 231 can be back flowed back into and be forced out.
That is, described refrigerant gas, can be with while the compressor 231, condenser 232 and heat exchanger 233 are circulated
Leaked-in air is cooled down repeatedly.
Pressure fan 220 can include air supply motor and the fan rotated by the air supply motor, and can be by institute
State the actuating speed of air supply motor and form air flow.
I.e., it is possible to extraneous air is flowed into inside the dehydrating unit 200 using the air flow, particularly will be described
Extraneous air is supplied to heat exchanger 233, such that it is able to carry out dehumidifying work to the extraneous air.
Temperature sensor 251 can measure the temperature of dehumidification portion 230 and temperature value output is arrived into control unit 240.One is real
Apply in example, temperature sensor 251 can measure the surface temperature of heat exchanger 233 and output temperature value.
Humidity sensor 252 can measure outer moisture and humidity value output is arrived into control unit 240.Humidity sensor
252 outer moistures that can measure dehydrating unit 200, i.e. measurement place the indoor humidity of dehydrating unit 200, and can give birth to
Into electric signal corresponding with the humidity of the measurement and it is sent to control unit 240.

And from the time of the humidity value below 40% of the input of humidity sensor 252 more than 1 minute when, control unit 240 is then judged as
Frost flower is generated in heat exchanger 233, and is converted to defrosting mode, such that it is able to the rotary speed of compressor 231 is reduced
To the 40% of normal speed speed and the rotary speed of pressure fan 220 increased to normal speed 130% speed, and
And the duration of the state gets over increase, more increases the decrement and the rotary speed of pressure fan 220 of the rotary speed of compressor 231
Incrementss.
In another embodiment, when for presetting humid tropical condition, control unit 240 can reduce compressor 231
Rotary speed and increase the rotary speed of pressure fan 220, so as to prevent compressor 231 from overloading.
Specifically, when the temperature value of the heat exchanger 233 being input into from temperature sensor 251 is in presetting second temperature value
More than, and when the humidity value of the input of humidity sensor 252 is more than the second presetting humidity value, control unit 240 can be with

Prevent compressor 231 from overloading.
In one embodiment, when humid tropical condition continues fiducial time, control unit 240 can be converted to overload protection.
Herein, overload protection pattern is the pattern for removing the overload occurred in compressor 231, such that it is able to according to institute
State the size of the humid tropical condition duration after fiducial time or the temperature value and humidity value and increase or decrease
The decrement of the rotary speed of compressor 231 and the incrementss of the rotary speed of pressure fan 220.
The polluter that includes is leached in the air that filter portion 210 can flow into inside dehydrating unit 200.That is, mistake
Filter portion 210 can remove the dirt with absorption by way of the polluter included in the leaked-in air of pressure fan 220
Dye material.
As illustrated, filter portion 210 may be located at air entry, according to another embodiment, the first filtering can be divided into
