Example Embodiment
[0070] Example 1: The experimental textile factory of the present invention is a textile factory in northern China. The workshop area is more than one thousand square meters, the main body is a steel structure building, and the roof is a spire. figure 1 As shown, the outer surface is thin steel plate, the inner surface is W-C veneer, the middle insulation material is Owens glass wool, and the workshop is equipped with a ceiling and an air-conditioned room. The temperature and humidity in the workshop are adjusted by the air-conditioning system. The temperature in the winter workshop is maintained at about 25℃ and the relative humidity is 70%. In the winter workshop, high-humidity water vapor permeates and diffuses through the ceiling gaps into the ceiling space. There are gaps in the WC veneer layer, and high-temperature and high-humidity water vapor enters the insulation through the gaps. In the material layer, when it reaches saturation and condenses into water, the glass wool ...
Example Embodiment
[0086] Example 2: Basically the same as Example 1, the similarities will not be repeated. The difference is that the cross section of the exhaust air dehumidification main pipe and the exhaust air dehumidification branch pipe are of equal section, and each exhaust air dehumidification branch pipe is along the roof direction Two rows of exhaust and dehumidification holes are arranged on both side walls approximately uniformly. The distance between the exhaust and dehumidification holes is 150mm, and the distance between the exhaust and dehumidification pipe network and the lower surface of the roof of the factory is 5mm.
[0087] The method of this embodiment is that when the relative humidity value detected by the humidity sensor reaches 70%, the control circuit starts the exhaust air dehumidification fan to extract high-humidity air near the lower surface of the roof of the factory building, and send it to the air-conditioned room of the workshop, or directly exhaust it outside W...
Example Embodiment
[0088] The third embodiment: It is basically the same as the first embodiment, and the similarities will not be repeated. The difference is that the exhaust air and dehumidification branch pipes are obliquely connected with the main pipe, and are arranged obliquely and equidistantly. The cross-section of the main pipe is of equal cross-section, the cross-sectional shape is elliptical ring, and the material is glass steel pipe. Each exhaust and dehumidification branch pipe has two rows of approximately uniformly arranged exhaust and dehumidification holes along the two side walls of the roof direction. The shape is oval, the distance between the exhaust and dehumidification holes is 50mm, and the distance between the exhaust and dehumidification pipe network and the lower surface of the roof of the factory building is 5mm.
[0089] The method of this embodiment is that when the relative humidity value detected by the humidity sensor reaches 82%, the control circuit starts the exhau...
