[0003] However, the limitation of this technology is that the frequency conversion dehumidifier frequency conversion cannot be too low, if the power of frequency conversion dehumidifier is too low, then it will lead to the fresh air not being sent into the room, and the room temperature and humidity control requirement cannot be met. On the other hand, the sealing property of electric air valve is not good, and the single use is easy to cause air leakage, and further increase the power consumption of frequency conversion dehumidifier.

[0049] an electric air valve 140, provided in the air supply branch pipe 131, for controlling the closure of the air supply branch pipe 131.

[0050] It can be understood that the frequency conversion dehumidification system 100 of the utility model cooperatively controls by introducing a plurality of circulating air cabinets 120, effectively solves the problem of air supply failure caused by the lower limit of the power of the frequency conversion dehumidifier 110 in the background art, and the air leakage energy consumption defect caused by the insufficient sealing of the electric air valve 140.

[0051] Specifically, by dividing the dry fresh air output by the single frequency conversion dehumidifier 110 into a plurality of circulating air cabinets 120, each circulating air cabinet 120 independently processes and delivers fresh air to the corresponding room 210, so that the frequency conversion dehumidification system 100 does not need to rely on the frequency conversion power adjustment of the single frequency conversion dehumidifier 110 to meet the dehumidification demand of each room 210. In specific applications, if it is necessary to open the air supply of all rooms 210, the circulating air cabinet 120 can still pressurize the fresh air to maintain effective air supply, avoiding the problem that the frequency conversion dehumidifier 110 cannot overcome the pipeline resistance due to too low air pressure, thereby effectively realizing the temperature and dehumidification control demand of each room 210.

[0052] It can also be understood that by setting the circulating air cabinet 120 to pressurize the air supply of each room 210, the fresh air replacement speed in the room 210 is accelerated, thereby helping to effectively control the temperature and cleanliness of each room 210.

[0053] It also needs to be explained that the cleanliness of the fresh air in the room 210 depends on the replacement speed of the fresh air in the room 210, if the replacement period of the fresh air in the room 210 is faster, the cleanliness of the fresh air in the room 210 is higher.

[0054] Further, in the embodiment, the electric air valve 140 is directly integrated in the air supply branch pipe 131 at the connection node of the air outlet interface 120c of the circulating air cabinet 120 and the air supply port 211 of the room 210.

[0063] Further, the variable frequency dehumidification system 100 further comprises a second return air flue 160, which is arranged in the room 210 and used to discharge part of the fresh air in the room 210 close to the air inlet of the variable frequency dehumidifier 110.

[0064] It can be understood that the second return air flue 160 can discharge a part of fresh air of the room 210 close to the air inlet of the variable frequency dehumidifier 110, and the variable frequency dehumidifier 110 re-controls temperature and dehumidification of the part of fresh air, and since the temperature and humidity of the part of fresh air are lower than those of the air in the sealed space 200, the setting of the second return air flue 160 can reduce the heat and humidity of the fresh air in the air flue handled by the variable frequency dehumidifier 110, so that energy saving and consumption reduction of the variable frequency dehumidifier 110 are realized.

[0067] Further, the air supply openings 211 are provided with filter pieces 170.

[0068] It can be understood that the setting of the filter pieces 170 can avoid that backflow air pollutes the air supply branch pipes 131 after the electric air valves 140 are closed.

[0069] Optionally, the air supply openings 211 are provided with windmill pieces 180. It can be understood that the windmill pieces 180 can be driven to rotate by a fresh air flow, so as to facilitate observation of the air supply condition of the air supply openings 211.

[0070] In specific embodiments of the utility model, the variable frequency dehumidifier 110 is a variable frequency rotary dehumidifier, the air supply pipeline 130 is provided with an air pressure sensor 190, the air pressure sensor 190 is signal connected with a variable frequency controller of the variable frequency rotary dehumidifier, and is used for controlling and adjusting the power of the variable frequency rotary dehumidifier. Specifically, the dehumidification efficiency of the variable frequency rotary dehumidifier is better, but the power consumption is larger, so that in specific applications, the air pressure sensor 190 is arranged to adaptively adjust the power of the variable frequency rotary dehumidifier, so that the overall power consumption of the variable frequency dehumidification system 100 is reduced while the temperature and dehumidification effect of the individual room 210 is realized.
