Technical field
The present invention relates to a kind of conditioner, and more particularly to one kind is with current-controlled central dehumidification system.
Background technology
In southern region of China, rainwater is more, and air humidity is big, indoors under environment, the higher climatic environment meeting of humidity
Cause metope, ground moist, can also bring discomfort to human body.Therefore, people can select dehumidification system to adjust indoor humidity.
And existing central dehumidification system, it can not often complete the independent control to each room humidity, it is impossible to meet small
The dehumidification of scope.And scattered dehumidification equipment but causes interior and makes an uproar, it is necessary to host to be arranged on to the inside in independent room
The increase of sound and the raising of building cost.
And on the other hand, current construction and installation fresh air system and dehumidification system, often using mutually independent two sets systems
System, this has been resulted in, and wind system pipeline in building is excessive, and design and installation difficulty increases, and the workload and cost of installation are also significantly
Increase.
Furthermore existing humidity control apparatus and regulating system, are substantially to be adjusted according to indoor humidity condition and blow
Amount, it is unstable according to the difference of indoor humidity, air output.Especially central dehumidification system, generally all sets frequency modulation dehumidifier, when
When air humidity is relatively low, air output reduces, and air-supply wind speed reduces, and the outlet air of air outlet is difficult to form circulation in the room, causes
Indoor air environment is uneven.And if to keep wind speed, needing dehumidifier, high load works always, high energy consumption.
The content of the invention
It is an object of the invention to solve existing central dehumidification system not realizing independent control, and individually dehumidification equipment is made an uproar
The problem of sound is big, of high cost, there is provided one kind is with current-controlled central dehumidification system.Another purpose of the use of the new type be by
A kind of dehumidification system combination fresh air system, there is provided central dehumidification system with Xingfeng capsule.The present invention's a further object is not
Under the premise of the energy consumption for influencing dehumidifier, ensure to blow in room dehumidification process and stablize.

Dry wind, realizes concentration dehumidifying, each room is individually blown.Return air is similar with air-supply, realizes the independent return air in each room, concentrates
Dehumidifying.Each room is blown by mixed ventilation machine, and mixed ventilation machine keeps air output to stablize, and is changed by the humidity in room,
Mixed ventilation machine mixing ratio is adjusted, when humidity is relatively low, then blowpipe air output is reduced, and secondary air channel is mended air quantity and improved；Conversely, work as
When humidity is higher, blowpipe air output improves, and secondary air channel is mended air quantity and reduced.Do not improving the premise of frequency conversion dehumidifier energy consumption
Under, ensure the air output stablized in room, ensure indoor air flows ambient stable, make indoor humidity uniform.And it is to use
The return air in this room carries out benefit wind, can guarantee that indoor air temperature is stablized.
Preferably, return air humidity sensor is respectively equipped with the port that each return air branch pipe is connected with each room,
Signal is connected between the adjusting valve of each corresponding return air humidity sensor in room and mixed ventilation machine.Return air humidity sensor is made
For the signal of each room humidity control, the mixed ventilation ratio for corresponding to room is controlled, meanwhile, the air output that interior is stablized makes return air
Humidity information it is more representative, can more accurately reflect indoor humidity real-time condition.
Preferably, the frequency conversion dehumidifier is additionally provided with the fresh air pipeline being in communication with the outside, each room is respectively equipped with row
Air port.When fresh air is supplemented, whole system internal pressure improves, and at this time by the individual row air port air draft in operation room, ensures room
Interior air pressure environment.
Preferably, the fresh air pipeline is equipped with adjustable new air-valve with frequency conversion dehumidifier junction, the return air is total
The carbon dioxide sensor of control new air-valve opening degree is equipped with pipe.New air-valve can change according to return air gas concentration lwevel
Open degree, so as to effectively control Leads to new breeze amount, reduces unnecessary Leads to new breeze and causes frequency conversion dehumidifier except humidity load
Increase, so as to reduce system energy consumption.
Preferably, being equipped with the baroceptor of monitoring pressure in the air supply plenum chamber, baroceptor is removed with frequency conversion
Wet machine signal is connected.The air pressure signal of air supply plenum chamber adjusts the foundation of rotating speed, energy-saving and frequency-variable as frequency conversion dehumidifier.
As other preferred, the air pressure sensing of monitoring pressure is respectively equipped with air supply plenum chamber and the return air plenum chamber
Device, baroceptor are connected with frequency conversion dehumidifier signal.The air pressure difference of air supply plenum chamber and return air plenum chamber is removed as frequency conversion
Wet machine adjusts the foundation of rotating speed, energy-saving and frequency-variable, and is exaggerated pressure signal, and control is more accurate.
Preferably, the mixed ventilation machine is equipped with the regulating device that can actively adjust total air output.It can adjust according to demand
Section air-supply total blast volume.
Preferably, the frequency conversion dehumidifier is DC frequency-changing dehumidifier.Frequency conversion dehumidifier uses DC power supply, uses city
Political affairs power supply is powered, and meets civilian demand.
The present invention concentrates dehumidifying using frequency conversion dehumidifier, by the transition of air supply plenum chamber and return air plenum chamber, to each
Independent room is individually blown, and realizes each room independent humidity control, effective control system energy consumption；Pass through the monitoring to return air carbon dioxide
Fresh air inlet air is controlled, it is effective to control Leads to new breeze amount, reduce unnecessary Leads to new breeze and cause frequency conversion dehumidifier to remove humidity load
Increase, so as to reduce system energy consumption；Meanwhile the direct mixed ventilation of part return air in each room is re-circulated to interior,
Ensure that room air-supply wind speed is stablized on the premise of not improving system energy consumption.
