Air distribution plenum chamber of fresh air system and mounting method of air distribution plenum chamber

Abstract

The invention discloses an air distribution plenum chamber of a fresh air system and a mounting method of the air distribution plenum chamber. The air distribution plenum chamber comprises a chamber body, a cover plate and air blocking pieces, air blocking piece mounting grooves are dug in the chamber body, the air blocking pieces comprise sleeve plates and telescopic plates, the telescopic plates are slidably mounted in the sleeve plates, the sleeve plates are detachably mounted in the air blocking piece mounting grooves, an air inlet is dug in the side wall of one side of the chamber body, and air outlets are dug in other side walls of the chamber body. Air flow in the chamber body is blocked through the arrangement of the air blocking pieces, air distribution of the air flow in the plenum chamber is facilitated, so that the air outlet volume of each air outlet is kept basically consistent, the air blocking area of the air blocking pieces is changed by changing the relative positions of the telescopic plates and the sleeve plates, the plenum chamber can be adjusted conveniently during mounting, and the mounting and adjusting efficiency is improved.

Description

technical field [0001] The invention belongs to the field of fresh air systems, in particular to an air volume distribution static pressure box of a fresh air system and an installation method thereof. Background technique [0002] People spend more than 80% of their time indoors. The Chinese standard stipulates that the indoor fresh air volume per capita should not be less than 30m 3 / h. But at present, most of the houses in our country do not have a fresh air system installed, and the means of ventilation are only the partial exhaust of kitchens and bathrooms or the way of opening windows for ventilation. Studies have shown that relying on the above means alone cannot meet the minimum demand for indoor fresh air. Therefore, in residential buildings, it is necessary to install a fresh air system. [0003] Compared with other buildings, residential buildings have lower floor height and smaller installation space, and it is difficult to adopt the air volume distribution m...

Problems solved by technology

[0003] Compared with other buildings, residential buildings have lower floor height and smaller installation space, and it is difficult to adopt the air volume distribution method of general ventilation system

At present, the air volume distribution of the fresh air system in the actual project only depends on the judgment of engineering experience, and it is impossible to ensure that the air volume of each room at the end reaches the standard, resulting in differences in the air intake volume of the fresh air system in each room
