Multipoint distributed type central ventilation system with nondestructive load-bearing effect and pipe laying method

Abstract

The invention relates to the fields of environment-friendly firefighting and air conditioner ventilation, in particular to a multipoint distributed type central ventilation system with a nondestructive load-bearing effect and a pipe laying method. The central ventilation system is connected with a static-pressure draught distributing box, and branch pipes separated from the static-pressure draughtdistributing box are distributed indoors; the branch pipes enter the room and are laid on a floor layer, and load-bearing walls and spandrel girders are not needed to be punched; the multiple branchpipes perform multipoint and multi-position air supply or air return; and indoor pipeline distribution includes one or more modes as follows: the load-bearing walls and the spandrel girders climb walls by the aid of parapet walls, that is, wall decoration is contained outside the load-bearing walls and the spandrel girders and assisted in hiding of the branch pipes; the load-bearing walls and thespandrel girders climb walls by growing, that is, grooves are formed in the load-bearing walls and the spandrel girders and the branch pipes climb walls along the formed grooves.

technical field [0001] The invention relates to the fields of environmental protection, fire protection and air conditioning and ventilation, in particular to a non-destructive and load-bearing multi-point distributed fresh air system and a pipeline laying method. Background technique [0002] Traditional fresh air systems are mostly PVC pipes and PE (double-wall corrugated) pipes. Generally, each room has one air supply port and one return air port. Uneven fresh air volume and poor air distribution lead to insufficient fresh air volume indoors (in the core comfort zone), which makes users feel stuffy.

Problems solved by technology

[0002] Traditional fresh air systems are mostly PVC pipes and PE (double-wall corrugated) pipes. Generally, each room has one air supply port and one return air port. Uneven fresh air volume and poor air distribution lead to insufficient fresh air volume indoors (in the core comfort zone), which makes users feel stuffy. From the simulation of fluent air distribution, we can see the disordered air distribution caused by the layout of traditional fresh air ducts and air outlets. sequence results

[0003] 2. In the traditional fresh air system, most of the air pipes in the indoor layout are PVC pipes or PE pipes, and the diameters are generally 75mm, 110mm, 160mm, etc., so it is not possible to lay pipes on the vertical wall, the ground, (or directly on the top surface), And the construction is troublesome, the installation limitations are very high, the degree of freedom is very low, and because the traditional fresh air system pipes are relatively thick, the openings are relatively large during installation. For the sake of the safety of the house structure, the property is clearly defined in order to protect the building's stress and earthquake resistance. It is stipulated that opening holes in shear walls and load-bearing beams is prohibited, resulting in the failure of many users to install fresh air systems

[0013] Combining the above two major characteristics, if the above problems are realized, the existing pipeline system cannot meet the demand; the developer’s reservation is a method, but it cannot match the personalized decoration layout requirements; so the above problems need to be solved to achieve a simple, economical and efficient system design. The method of environmental protection and easy installation does not require drilling of load-bearing beams and shear walls, and realizes personalized multi-point precise air supply requirements
