Embodiment Construction
[0016] A fresh air collection device that uses the night sky to dehumidify (refer to Figures 1, 2, 3, and 4). The device includes a heat exchange network 1 , a fresh air collection funnel 2 , a static pressure box 6 and a fresh air guide pipe 4 . Among them, the heat exchange network 1 is installed in the edge of the open end of the fresh air collection funnel 2 in a state of being high in the middle and low around the periphery. Pipe 61 communicates with the air supply shaft in the building (the air supply shaft in the building and its interior is omitted and not shown). The lower end of the fresh air guide pipe 4 is fixedly arranged in the static pressure box 6, and its upper end is not lower than the intersection of the funnel tube of the fresh air collection funnel 2 and the funnel horn, and there is a water diversion gap between the funnel tube and the funnel tube. Pass through this funnel pipe (the arrow under the air supply pipe 61 in Fig. The ground bag clamps the fr...

The invention relates to a new air collection device which utilizes night air for dehumidification. The device comprises a heat exchanger network, a new air collection funnel, a static pressure box and a new air guide pipe; wherein, the heat exchanger network is arranged in the edge of an open end of the new air collection funnel in the state of high in the middle and low in the periphery, the new air collection funnel is arranged above the static pressure box which is communicated with an air supply well in a building construction by a section of air supply pipe; the lower end of the new air guide pipe is fixedly arranged in the static pressure box, the upper end thereof penetrates a funnel pipe in the state of not lower than the intersection of the funnel pipe and the funnel speaker of the new air collection funnel and retaining a water guide clearance with the funnel pipe; the lower end of the funnel pipe seamlessly packages the new air guide pipe and is communicated with a drainage pipe of condensate water. The new air collection device of the invention has simple structure, and the greatest advantage of being capable of providing the new air which is subjected to dehumidification treatment for a room without the need of additional energy source.
Description
technical field [0001] The invention relates to a device for dehumidifying fresh air. Background technique [0002] The existing scientific research results have fully realized that when the indoor relative humidity is high, it will have adverse effects on the comfort of the human body and the health of the occupants. In addition, high humidity can also cause condensation on the internal structure of the building, reducing the strength of building components. For this reason, when people deliver fresh air from the outside (commonly known as fresh air) indoors, it is often necessary to dehumidify the fresh air in advance. In areas with hot summer and cold winter, hot summer and warm winter climates, due to the humid outdoor air, it is necessary to dehumidify the collected fresh air. [0003] At present, the commonly used methods of air dehumidification are: adsorption dehumidification method, freezing dehumidification method, and ventilation dehumidification method. The ad...
