Embodiment Construction

[0032] Examples see figure 1 , figure 2 As shown, the construction method of the air duct in this full displacement fresh air system has the following steps.

[0033] Step 1. During the construction of the building structure, reserve an opening for the exhaust pipe on the wall near the lower part of the ceiling where the exhaust pipe 1 needs to go.

[0034] Step 2. After the construction of the building structure is completed, install the exhaust pipe 1 and the fresh air supply pipe 3 located in the fresh air supply pipe well 5 and the fresh air room 6, and open the exhaust pipe on the exhaust pipe in the fresh air supply pipe well. Pipe connection port, open the fresh air supply pipe connection port on the fresh air supply pipe in the fresh air supply pipe well.

[0035] Step 3: Install the indoor exhaust duct and fresh air supply duct.

[0036]Regarding the installation of the indoor exhaust pipe, the indoor exhaust pipe is first laid along the ceiling, and the indoor ex...

Abstract

The invention relates to a construction method of an air pipe in a full displacement type fresh air system. The construction method comprises the following steps: step one, reserving an exhaust pipe hole port in a building structural construction; step two, after completing the building construction structure, installing exhaust pipes and fresh air blast pipes positioned in exhaust pipe wells and an fresh air machine room; and step three, installing exhaust pipes and the fresh air blast pipes in a chamber, wherein the installation of the fresh air blast pipes further comprises the following steps: reserving a die box on the position in which a fresh air outlet is located while arranging an electric pipeline and a water supply and drainage pipeline; arranging the fresh air blast pipes in the chamber after arranging the electric pipeline and the water supply and drainage pipeline; pouring a foamed concrete cushion, and painting a cement mortar for levelling layers; installing an air supply outlet on the fresh air outlet of the fresh air blast pipes in the chamber; and filling the construction space used for installing the air distributor. The method solves the problem of long construction period of the full displacement type fresh air system, and prevents the fresh air system from being damaged from pre-burying to running.

Description

technical field [0001] The invention relates to a construction method for an air duct installed in a fresh air system in a building. Background technique [0002] In the past, it was difficult to control the quality of indoor air in residential houses. Generally, the windows were opened for ventilation, and whether the windows were opened or not was all controlled by the owner. However, this is limited by many practical conditions. For example, it is too cold to open the windows in winter, and it is too hot to open the windows in summer, or the windows are not opened to keep the room quiet during rest, so that the windows cannot be opened for ventilation. [0003] There is a full-replacement fresh air system. The air ducts in the fresh air system include exhaust ducts and fresh air supply ducts. Some of the exhaust ducts are laid along the lower surface of the ceiling, and some of the fresh air supply ducts are buried above the floor structure. In the cushion layer, the rem...
