Put, it includes one for being used to detect the environmental test chamber of the large volume of the objects such as automobile and being arranged in big environmental test chamber
Or multiple environmental test chambers for being used to detect the small size of the objects such as furniture.Formaldehyde and VOC detect that requiring certain puts in furniture
Change in rate, standard and require as 0.5-1 times per hour, equivalent to the temperature and humidity control under an open occasion, it is general using dew
Point method, but its to control wet speed slower, control that wet device design is complicated, cost is higher, and the mode of traditional dry and wet air mixing is very
Easily cause fluctuation.
Dry and wet air control is regulated because there is VOC burst size detection platforms nacelle to accumulate under non-constant characteristic, large volume
After the relevant parameter of wet device, relative humidity is likely to result in when the test chamber of small size is used and fluctuates larger or even can not reach
To the situation of relative humidity, and it is unable to reach and controls wet technical requirements respectively.
Utility model content
For the above-mentioned problems in the prior art, the utility model provides a kind of can solve the problem that under different volumes
The VOC burst size detection platforms that regulation of relative humidity problem, the wet speed of control are fast, humidity is difficult fluctuation, equipment cost is low are open
Regulation of relative humidity device.
The utility model is achieved by the following technical solution：A kind of VOC burst sizes detection platform is open relative
Humidity control apparatus, the VOC burst sizes detection platform includes being provided with outside test chamber A, the test chamber A to be supplied for adjusting
The aeration device of air humidity degree, the aeration device includes top and connects the dew point water tank for being used to dehumidify of fresh air pipeline and pass through pipe
The ultrasonic humidifier for being used to humidify that road is connected with the fresh air pipeline, the outlet of the fresh air pipeline of the aeration device is passed through
Inside the test chamber A, it is characterized in that：At least one test chamber B is internally provided with the test chamber A, the test chamber B's
Intake stack is connected with the fresh air pipeline of the aeration device in test chamber A, each test chamber B intake stack
On be equipped with connected water screen humidifying device.
In the utility model, entered using the aeration device being arranged on outside test chamber A using dew point dehumidification mode to fresh air
Row concentrates dehumidifying, fresh air is kept a relatively low dew point value, the dry air provided by aeration device in cabin to removing
It is wet, each test chamber B is individually humidified using water screen humidifying device, by setting the relative of different cabins in the controls
Humidity value can realize the humid control to different cabins.
The beneficial effects of the utility model are：The utility model is solved by using the mode concentrated dehumidifying, individually humidified
The problem of humidity can not controlled respectively between different cabins, and to cuddy by the way of concentrating dehumidifying, individually humidifying
Control wet speed fast, humidity is difficult fluctuation；The design of centralization dehumidifying can effectively reduce the manufacturing cost and use cost of equipment, and
And in VOC burst size detection platforms to different volume of compartments all can be effective control it is wet, solve the wet equipment of high-power control and draw
The problem of playing cuddy moisture fluctuation, the wet equipment of small-power control uncontrollable big cabin humidity.
