Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0028] The main idea of ​​the present invention is to enable the dehumidifier to adjust the direction of the refrigerant circuit according to the change of the air humidity in the dehumidification room 2 by setting a humidity sensor 7 and a reversing valve 6, thereby accelerating the evaporation of water from water-containing objects in the dehumidification room 2 while reducing the air humidity, effectively improving the dehumidification efficiency of the dehumidifier and accelerating the drying speed of the environment.

[0029] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. The numbers of any elements in the drawings are for illustration only and not for limitation, and any names are for distinction only and do not have any limiting meaning.

[0030] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0031] Example 1 of a dehumidification device for a specific space provided by the present invention:

[0032] like Figure 1 As shown, the device includes a compressor 1, which is a screw compressor 1. A heat exchanger 3 is provided on one side of the compressor 1. The side where the heat exchanger 3 is located is defined as the left side. A throttling device 4 is provided on the left side of the heat exchanger 3. The throttling device 4 is an electronic expansion valve, which improves the control accuracy of the refrigerant flow and the stability of the dehumidification device while throttling and reducing the pressure; a heat exchanger 2 5 is provided between the throttling device 4 and the compressor 1. Both the heat exchanger 1 3 and the heat exchanger 2 5 are fin-type heat exchangers to improve the heat exchange efficiency of the heat exchanger. The compressor 1, the heat exchanger 3, the throttling device 4 and the heat exchanger 2 5 are connected in sequence to form a loop.

[0033] A dehumidification room 2 is provided on the rear side of the heat exchanger 3, and a U-shaped channel 21 is provided on the rear side of the dehumidification room 2. The heat exchanger 3 is located at the front end of the U-shaped channel 21, and fans 22 are provided at both ends of the left and right sides of the channel. The left fan 22 is located at the left front end of the U-shaped channel 21, and the wind direction of the left fan 22 faces backward. The right fan 22 is located at the right rear end of the U-shaped channel 21, and the wind direction of the right fan 22 faces forward, so that the air in the dehumidification room 2 circulates between the dehumidification room 2 and the heat exchanger 3. An air filter 10 is provided at the rear end of the right fan 22 to remove dust in the air.

[0034] The compressor 1 is provided with a reversing valve 6, which is an electromagnetic four-way reversing valve 6. A humidity sensor 7 is provided in the dehumidification room 2, and a remote communication module 9 is also provided in the dehumidification room 2 to improve the convenience of equipment operation; a controller 8 is provided at the top of the compressor 1, and the controller 8 is used to adjust the operating frequency of the compressor 1, the speed of the fan 22 and the opening degree of the throttling device 4 according to the set value and feedback data from the humidity sensor 7 to achieve fine control of the humidity.

[0035] The working principle of the device is as follows: when the humidity sensor 7 senses that the air humidity in the dehumidification room 2 has reached the set upper limit, the controller 8 controls the reversing valve 6 to make the circuit run in the clockwise direction. At this time, the heat exchanger 1 3 acts as an evaporator, which absorbs the heat of the air in the U-shaped channel 21 to convert the liquid refrigerant in the circuit into a gaseous refrigerant, thereby reducing the temperature of the air in the channel and condensing the water vapor in the air into water, thereby reducing the air humidity in the dehumidification room 2.

[0036] When the humidity sensor 7 senses that the air humidity in the dehumidification room 2 has dropped to the set lower limit, the controller 8 controls the reversing valve 6 to make the circuit run counterclockwise. At this time, the heat exchanger 1 3 acts as a condenser, and by converting the gaseous refrigerant into liquid refrigerant, it releases heat into the U-shaped channel 21, thereby increasing the temperature of the air in the U-shaped channel 21, thereby increasing the temperature of the dehumidification room 2 and accelerating the evaporation of water from the water-containing objects in the dehumidification room 2. When the air humidity in the dehumidification room 2 reaches the set upper limit again, the humidity sensor 7 will control the reversing valve 6 to operate again and repeat the above process.

[0037] Example 2 of a dehumidification device for a specific space provided by the present invention:

[0038] The main difference between it and Example 1 is:

[0039] In Example 1, the left fan is located at the left front end of the U-shaped channel.

[0040] In this embodiment, the left fan is located at the left rear end of the U-shaped channel.

[0041] Example 3 of a dehumidification device for a specific space provided by the present invention:

[0042] The main difference between it and Example 1 is:

[0043] In Example 1, the air filter is located at the right rear end of the U-shaped channel.

[0044] In this embodiment, the air filter is located at the left rear end of the U-shaped channel.
