The regeneration air inlet valve I 28 is opened, and the regeneration air inlet valve II 8 is closed. The regeneration air outlet valve I 30 is opened, and the regeneration air outlet valve II 31 is closed.

[0044] The outdoor fresh air is filtered by the fresh air filter 1 and then enters the air inlet chamber 34. After being driven by the fresh air fan 2, the fresh air is cooled and dehumidified by the fresh air cooling coil 3 to become low-temperature and high-relative-humidity air, and then enters the treatment air inlet channel 40. The low-temperature and high-relative-humidity air is dehumidified by the coating coil 7 in the dehumidification mode and becomes low-temperature and low-relative-humidity dry air, and then enters the treatment air outlet channel 42 through the treatment air outlet valve 26 and then enters the intermediate chamber 36.

[0045] At the same time, the first air valve 9 and the second air valve 10 are opened. The outdoor fresh air enters the regeneration air pipe 11 through the air inlet and exhaust pipe 45 and is mixed with the exhaust air from the regeneration area 142 of the dehumidification runner 14, and then enters the regeneration air inlet channel 43 and the coating dehumidification channel 47 in the upper part through the regeneration air inlet valve 28. The coating coil 29 in the regeneration mode is regenerated and desorbed, and the regeneration air becomes high-temperature and high-humidity air, and then enters the regeneration air outlet channel 41 through the regeneration air outlet valve 130 and is driven by the second regeneration fan 4 to be discharged outdoors.

[0046] In the second working condition, the coating coil 29 is dehumidified and the coating coil 7 is in the regeneration mode. The treatment air inlet valve 5 is opened and the treatment air inlet valve 6 is closed, the treatment air outlet valve 127 is opened and the treatment air outlet valve 126 is closed, the regeneration air inlet valve 8 is opened and the regeneration air inlet valve 28 is closed, and the regeneration air outlet valve 131 is opened and the regeneration air outlet valve 130 is closed.

After being driven by the fresh air fan 2, the fresh air is cooled and dehumidified by the fresh air cooling coil 3 to become low-temperature and high-relative-humidity air, and then enters the treatment air inlet channel 40. The low-temperature and high-relative-humidity air is dehumidified by the coating coil 7 in the dehumidification mode and becomes low-temperature and low-relative-humidity dry air, and then enters the treatment air outlet channel 42 through the treatment air outlet valve 26 and then enters the intermediate chamber 36.

[0048] At the same time, the first air valve 9 and the second air valve 10 are opened. The outdoor fresh air enters the regeneration air pipe 11 through the air inlet and exhaust pipe 45 and is mixed with the exhaust air from the regeneration area 142 of the dehumidification runner 14, and then enters the regeneration air inlet channel 43 and the coating dehumidification channel 47 in the upper part through the regeneration air inlet valve 28. The coating coil 29 in the regeneration mode is regenerated and desorbed, and the regeneration air becomes high-temperature and high-humidity air, and then enters the regeneration air outlet channel 41 through the regeneration air outlet valve 130 and is driven by the second regeneration fan 4 to be discharged outdoors.

[0050] The outdoor fresh air is purified and filtered by the fresh air filter 1 and then enters the air inlet chamber 34. After being driven by the fresh air fan 2, the air passes through the fresh air surface cooler 3 to be cooled and dehumidified, and is processed into low-temperature and high-relative-humidity air, which then enters the processing air inlet channel 40. Part of the low-temperature and high-relative-humidity air enters the coated dehumidification channel 47 located on the upper side through the processing air inlet valve 26, is adsorbed and dehumidified by the coated coil 17 in the dehumidification working condition, and is processed into low-temperature and low-relative-humidity dry air, which then enters the processing air outlet channel 42 through the processing air outlet valve 126 and then enters the intermediate chamber 36.

[0052] The dehumidification rotary wheel 14 processing flow is as follows:

[0053] The low-dew-point return air in the room enters the intermediate chamber 36 through the return air inlet 25 and mixes with the low-temperature and low-relative-humidity dry air dehumidified by the coated coil as described above, is then driven by the processing fan 24 to be warmed, is purified and filtered by the first F8 filter 23, is cooled by the middle surface cooler 22 to be low-temperature and dry air, and enters the rotary wheel dehumidification chamber 37. Part of the low-temperature and dry air further adsorbs and dehumidifies dry air to become super-low-dew-point dry air in the treatment area 141 of the dehumidification rotary wheel 14 to the right, and then enters the air supply chamber 38. According to the temperature and humidity requirements of the air supply, the air can be further cooled by the rear surface cooler 21 or warmed by the rear heater 20, is then purified and filtered by the second F8 filter 19, and is supplied into the room through the air supply inlet 18.

[0054] The dehumidification rotary wheel 14 regeneration flow is as follows:

[0055] The low-temperature dry air of the other part of the aforementioned air enters the dehumidification chamber 37 of the rotary dehumidifier, passes through the cold-blowing area 143 of the dehumidification rotary dehumidifier 14 to the right, cools and blows the dehumidification rotary dehumidifier 14 just passing through the regeneration area 142, reduces the temperature of the rotary core in this area, so that the air entering the treatment area 141 can realize low dew point dehumidification; in addition, the air passing through the cold-blowing area 143 to the right can obtain high-temperature low-dew-point dry air (on the one hand, it can reduce the heat for heating regeneration of the dehumidification rotary dehumidifier 14, and on the other hand, it can better regenerate and dry the dehumidification rotary dehumidifier 14), then enters the heating chamber 44 through the cold-blowing air box 16, becomes high-temperature low-dew-point dry air after being heated by the steam regeneration heater 17, enters the regeneration air inlet box 15, then passes through the regeneration area 142 of the dehumidification rotary dehumidifier 14 to the left, regenerates the dehumidification rotary dehumidifier 14, and the exhaust air after regeneration becomes medium-high-temperature dry air, enters the regeneration air outlet box 13, then is driven by the first regeneration air blower 12 to enter the regeneration air pipe 11, is directly discharged from the room through the air inlet and outlet pipe 45 or enters the regeneration air inlet channel 43 as the regeneration air inlet of the coated coil in the regeneration working condition.
