Description
Technical field
The present invention relates to a kind of conditioner, particularly one is with current-controlled central dehumidification system.
Background technology
In south China area, rainwater is more, and air humidity is large, and under indoor environment, the climatic environment that humidity is higher can cause metope, ground humidity, also can bring discomfort to human body.Therefore, people's humidity that dehumidification system can be selected to come in conditioning chamber.
And existing central dehumidification system, often cannot complete that the independence of each room humidity is controlled, dehumidification among a small circle can not be met.And the dehumidification equipment of dispersion, need the inside be arranged on by main frame between independent housing, but cause the increase of room noise and the raising of building cost.
And on the other hand, current construction and installation VMC and dehumidification system, often use two separate cover systems, it is too much that this just causes wind system pipeline in building, and design and installation difficulty strengthens, and workload and the cost of installation also increase greatly.
Moreover existing humidity control apparatus and regulating system, be substantially all regulate air output according to the humidity condition of indoor, according to the difference of indoor humidity, air output is unstable.Especially central dehumidification system, generally all arranges frequency modulation dehumidifier, and when air humidity is lower, air output reduces, and air-supply wind speed reduces, and the air-out of air outlet is difficult to form circulation in room, causes indoor air environment uneven.And if wind speed will be kept, then need dehumidifier high capacity work always, energy consumption is high.
Summary of the invention
The object of the invention is to solve existing central dehumidification system and cannot realize independent control, and the problem that dehumidification equipment noise is large, cost is high separately, provide a kind of band current-controlled central dehumidification system.This uses another novel object to be by dehumidification system in conjunction with VMC, provides a kind of central dehumidification system with Xingfeng capsule.Also object of the present invention is under the energy consumption prerequisite not affecting dehumidifier, ensures that in room dehumidification process, air-supply is stable.
The technical solution adopted for the present invention to solve the technical problems is: the current-controlled central dehumidification system of a kind of band, comprise frequency conversion dehumidifier, frequency conversion dehumidifier is connected with air supply plenum chamber by header pipe, air supply plenum chamber is connected to some separate rooms by several blowpipes, the end that blowpipe is connected with room is provided with mixed ventilation machine, each room connects return air plenum chamber respectively by return air arm, return air plenum chamber is returned by return air house steward and is connected to frequency conversion dehumidifier, the return air arm in each room is all connected with the mixed ventilation machine in this room by secondary air channel, mixed ventilation machine is provided with the adjusting valve regulating blowpipe and secondary air channel air intake ratio.The blowpipe that this device is independently arranged by each room is blown separately, each blowpipe unifies air distribution by air supply plenum chamber, when pressure in air supply plenum chamber reduces, the work of frequency conversion dehumidifier is that air supply plenum chamber supplements dry wind, achieves and concentrates dehumidifying, each room blows separately.Return air is similar with air-supply, achieves the independent return air in each room, concentrates dehumidifying.Blown by mixed ventilation machine in each room, mixed ventilation machine keeps air output to stablize, and by the humidity change in room, regulate mixed ventilation machine mixing ratio, when humidity is lower, then blowpipe air output reduces, and secondary air channel is mended air quantity and improved; Otherwise when humidity is higher, blowpipe air output improves, secondary air channel is mended air quantity and is reduced.Under the prerequisite not improving frequency conversion dehumidifier energy consumption, ensure air output stable in room, ensure indoor air flows ambient stable, make indoor humidity even.And be adopt the return air in this room to carry out benefit wind, can ensure that indoor air temperature is stablized.
As preferably, the port that described each return air arm is connected with each room is respectively equipped with return air humidity sensor, and between the return air humidity sensor that each room is corresponding and the adjusting valve of mixed ventilation machine, signal is connected.The signal that return air humidity sensor controls as each room humidity, controls the mixed ventilation ratio in corresponding room, and meanwhile, indoor stable air output makes the humidity information of return air have more representativeness, more accurately can reflect indoor humidity real-time condition.
As preferably, described frequency conversion dehumidifier is also provided with the fresh air pipeline be in communication with the outside, and each room is respectively equipped with exhaust outlet.When new wind supplements, in whole system, pressure improves, and now by the independent exhausting mouth air draft running room, ensures room pressure environment.
As preferably, described fresh air pipeline and frequency conversion dehumidifier junction are provided with adjustable new air-valve, and described return air house steward place is provided with the carbon dioxide sensor controlling new air-valve opening degree.New air-valve can change open degree according to return air gas concentration lwevel, thus effective control Leads to new breeze amount, reduce unnecessary Leads to new breeze and cause frequency conversion dehumidifier except the increase of humidity load, thus reduce system energy consumption.
As preferably, be provided with the baroceptor of monitor force in described air supply plenum chamber, baroceptor is connected with frequency conversion dehumidifier signal.The air pressure signal of air supply plenum chamber as the foundation of frequency conversion dehumidifier adjusting rotary speed, energy-saving and frequency-variable.
As other preferred, be respectively equipped with the baroceptor of monitor force in described air supply plenum chamber and return air plenum chamber, baroceptor is connected with frequency conversion dehumidifier signal.The air pressure difference of air supply plenum chamber and return air plenum chamber is as the foundation of frequency conversion dehumidifier adjusting rotary speed, and energy-saving and frequency-variable, and be exaggerated pressure signal, controls more accurate.
As preferably, described mixed ventilation machine is provided with can the adjusting device of the total air output of active adjustment.Air-supply total blast volume can be regulated according to demand.
As preferably, described frequency conversion dehumidifier is DC frequency-changing dehumidifier.Frequency conversion dehumidifier adopts dc source, uses municipal Power supply, meets civilian demand.
The present invention adopts frequency conversion dehumidifier to concentrate dehumidifying, by the transition of air supply plenum chamber and return air plenum chamber, blows separately, realizes each room independent humidity control, effective control system energy consumption between each independent housing; By controlling new wind air intake to the monitoring of return air carbon dioxide, effective control Leads to new breeze amount, reduces unnecessary Leads to new breeze and causes frequency conversion dehumidifier except the increase of humidity load, thus reduce system energy consumption; Meanwhile, the direct mixed ventilation of part return air in each room is re-circulated to indoor, under the prerequisite not improving system energy consumption, ensures that room air-supply wind speed is stablized.
