Description

Technical Field

[0001] The invention belongs to the technical field of indoor air supply, and in particular relates to a uniform ventilation pipeline and an exhaust floor in a passive house. Background Art

[0002] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

[0003] Professor Adamson of the University of Dron, Sweden, and Dr. Feist of Germany first proposed the concept of passive house in 1988. It refers to a building that does not use traditional air conditioning systems but relies on the good thermal insulation and air tightness of its own external envelope structure to maintain a comfortable internal thermal environment. Passive houses include passive low-energy buildings, ultra-low-energy buildings, and near-zero-energy buildings.

[0004] Building ventilation is divided into natural ventilation and mechanical ventilation, which means that the dirty air in the building is directly or purified and then discharged to the outside, and fresh air is added to keep the indoor air environment in line with the hygienic standards. In the existing technology of exhausting through the floor, although the exhaust vents on the floor are evenly arranged, the distance between the exhaust vents and the exhaust fan is not the same, which is not a truly uniform exhaust. How to achieve uniform exhaust on the floor is a technical problem that needs to be solved urgently in this field. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is how to achieve uniform exhaust of the floor.

[0006] In order to solve the above technical problems, the present invention provides a uniform ventilation duct in a passive house, wherein the ventilation duct is a tree structure, wherein the multiple subtrees of the tree structure are multiple ventilation duct segments, wherein the multiple leaf nodes of the tree structure are multiple first pipe openings, wherein a root node of the tree structure is a second pipe opening, and the other nodes of the tree structure are connection points of different ventilation duct segments, wherein there is a shortest ventilation channel between each of the first pipe openings and the second pipe openings, and the volumes of different shortest ventilation channels are the same.

[0007] As a further improvement, the ventilation areas and lengths of the different shortest ventilation channels are the same.

[0008] As a further improvement, the ventilation pipe section is a hose.

[0009] As a further improvement, the degree of each node of the tree structure is greater than or equal to 3.

[0010] As a further improvement, the depth of the tree of the tree structure is less than or equal to 3.

[0011] The present invention also provides another technical solution: an exhaust floor in a passive room, comprising a floor and an exhaust fan, wherein the floor is evenly distributed with a plurality of exhaust ports, and further comprising the ventilation duct, wherein the ventilation duct is arranged below the floor, wherein the plurality of first pipe ports are respectively connected to the plurality of exhaust ports, and the second pipe port is connected to the exhaust fan, and the exhaust fan drives the air in the enclosed space to be discharged from the exhaust ports.

[0012] As a further improvement, the floor comprises a plurality of floor blocks spliced ​​together, and the air exhaust vents are arranged at the splicing gaps between different floor blocks.

[0013] As a further improvement, the exhaust port is a long slot-shaped exhaust port, and the long slot-shaped exhaust port is parallel to the splicing gap.

[0014] As a further improvement, the exhaust vents are hole-shaped exhaust vents, and the hole-shaped exhaust vents are arranged at the intersection of different splicing gaps.

[0015] Due to the application of the above technical scheme, the present invention has the following advantages compared with the prior art: the uniform ventilation ducts and exhaust floors in the passive house disclosed by the present invention, the ventilation ducts adopt a tree structure, which ensures that the exhaust volume between each exhaust port and the exhaust channel is the same, realizing truly uniform ventilation.
