Valve 4 and Dewpoint controller connect.Arranged by above structure, further increase this utility model control mode motility and
Automatically degree is managed.As, when a certain user nobody time, its can by PLC control device close house steward's Electric air valve 4 to cut
Disconnected Leads to new breeze, and the dew point temperature in each room is detected by Dewpoint controller, and the temperature signal of detection is transferred to PLC control
Device processed, PLC controls device and gets final product the start and stop of automatic control unit dehumidifier 2 according to the service condition set, thus it ensures
Indoor do not condense.This structure can farthest reduce energy consumption in the case of meeting dehumidification requirements, has preferable practicality.
As detailed description of the invention, this utility model allows the indoor end of each user new wind house steward 3 be connected with the draught distributing box 5 of setting,
Draught distributing box 5 is made to be connected with each room with air port by airduct.Allow the indoor unit dehumidifier 2 of each user at least provided with one, make
Unit dehumidifier 2 is in the Room and utilizes return air to dehumidify.This structure set-up mode, makes new wind not enter unit dehumidifier
2, and it is sent directly into each room by draught distributing box 5 and corresponding airduct and air port, it is ensured that the quality of new wind.Make in the Room simultaneously
Unit dehumidifier 2 return air is processed drying regime after be re-fed in the Room, indoor air quality can be made to keep stable, and newly
Also can guarantee that when blower fan group 1 is closed that indoor do not condense.It should be noted that unit dehumidifier 2 is not limited to be arranged in the Room, also
Can be arranged as required in other indoor positions.
The schematic diagram of the second embodiment of a kind of step of this utility model combined type dehumidification system as shown in Figure 4 and Figure 5, with
Unlike the first embodiment, the second embodiment allows the indoor end of each user new wind house steward 3 and the pipeline leading in the Room
Connect.Allow the indoor unit dehumidifier 2 of each user at least provided with one, and allow unit dehumidifier 2 be in the Room and to utilize return air
Dehumidify, and make the air outlet of unit dehumidifier 2 be connected with the draught distributing box 5 of setting by pipeline, pipeline arranges pipeline
Blower fan, allows draught distributing box 5 be connected with each room with air port by airduct simultaneously.The second embodiment makes new wind not enter unit to remove
Wet machine 2, does not the most send into each room, but is sent directly in the Room, and is processed by return air dry by the unit dehumidifier 2 in the Room
Each room is sent into through draught distributing box 5 and corresponding airduct and air port again after dry state.This structure can ensure New atmosphere quality, makes room
Interior air quality is stable, and makes the dehumidifying in each room all be ensured.Identical with the first embodiment, unit dehumidifier 2 is not
It is limited to be arranged in the Room, it is also possible to be arranged as required in other indoor positions.
The schematic diagram of the third embodiment of a kind of step of this utility model combined type dehumidification system as shown in Figure 6 and Figure 7, with
Unlike first two embodiment, the third embodiment allows the indoor unit dehumidifier 2 of each user at least provided with one, allows
The indoor end of each user new wind house steward 3 is connected with the air inlet of unit dehumidifier 2 by pipeline, allows the air-out of unit dehumidifier 2
Mouth is connected with the draught distributing box 5 of setting by pipeline, and arranges pipeline fan on pipeline, allows draught distributing box 5 by airduct and air port
Connect with each room.Meanwhile, the air inlet at unit dehumidifier 2 arranges backwind tube, and arranges the electronic wind of return air on backwind tube
Valve 6, allows return air Electric air valve 6 control device with PLC and is connected.The third embodiment makes new wind be directly entered unit dehumidifier
2, and backwind tube and corresponding return air Electric air valve 6 are set at the air inlet of unit dehumidifier 2, make the unit dehumidifier 2 can spirit
New wind or return air are dehumidified with living, and the dry air obtained is sent into each by draught distributing box 5 and corresponding airduct and air port
Room.Specifically, under normal circumstances, make return air Electric air valve 6 close, and make house steward's Electric air valve 4 open, allow new wind lead to
The pipeline crossing new wind house steward 3 and correspondence enters unit dehumidifier 2, and unit dehumidifier 2 passes through phase after Fresh air handing is become dry air
Each room is sent in pipeline, draught distributing box 5, airduct and the corresponding air port answered, makes the fresh air supply in each room and effect on moisture extraction all obtain
To ensureing.When new wind inferior quality closes Fresh air handling units 1, or when user's unmanned cut-out fresh air channel, now make return air electricity
Wind symptom valve 6 is opened, and makes house steward's Electric air valve 4 be closed, and unit dehumidifier 2 passes through after return air is processed into dry air
Each room is sent into, to ensure that indoor do not condense in corresponding pipeline, draught distributing box 5, airduct and corresponding air port.Implement with first two
Mode is identical, and unit dehumidifier 2 is not limited to be arranged in the Room, it is also possible to be arranged as required in other indoor positions.?
In three kinds of embodiments, control device by PLC and house steward's Electric air valve 4 and return air Electric air valve 6 can be made to use interlocking reversely control
Mode processed, i.e. then allow return air Electric air valve 6 close when house steward's Electric air valve 4 is opened, when house steward's Electric air valve 4 is closed
Return air Electric air valve 6 is then allowed to open.This control mode can improve automated management degree, further enhances practicality.
It should be noted that in actual applications, Fresh air handling units 1 surface cooler therein of the present utility model uses variable-flow
System, what the blower fan in Fresh air handling units 1 should be adopted is frequency conversion fan, makes the Fresh air handling units can be according to the actual need of each user's resh air requirement
Measure the power of rate-of flow and the blower fan changing in surface cooler dynamically, to realize the maximization of utilization of energy, and reduce energy consumption,
Saving the energy, so the operating cost in the whole service cycle can be significantly lower than traditional new wind central dehumidification system.
Above example is only the description carrying out preferred implementation of the present utility model, not this utility model is claimed
The restriction that scope is carried out, on the premise of without departing from this utility model design spirit, this area engineers and technicians are according to this practicality
The various forms of deformation that novel technical scheme is made, all should fall into the protection domain that claims of the present utility model determine
In.
