Embodiment Construction

[0018] Concrete structure and implementation of the present invention are described in further detail below in conjunction with specific accompanying drawing:

[0019] The power displacement ventilation air supply device provided by the present invention includes an air induction port 4 , a booster fan 1 , a streamlined flow equalizing partition 2 and an outlet grille 3 . The streamlined flow equalizing partition 2 is arranged between the booster fan 1 and the outlet grille 3 , and a quadratic cavity is formed between the partition board and the outlet grille 3 . The streamlined flow equalizing partition 2 is composed of an inclined arc partition 5 and a vertical arc partition 6 arranged below the inclined arc partition; one side of the inclined arc partition 5 is a straight line , the other side is arc-shaped; the vertical arc partition 6 is a quadratic cylindrical shape, and the curvature of the arc-shaped side on the top of the vertical arc partition 6 is the same as that o...

Abstract

A dynamo driven ventilation and air blast exchanger features in the even flow and dynamo driven characteristics. Based on the traditional device, it adds an inside linear even flow barricade between which and the output grid forms into a secondary curve cavity. Due to the shape and structure of the linear even flow barricade, remaining constant differential static pressure at the end of the wind channel, sending the wind to wind blast device through the wind channel. After the treatment of the linear even flow barricade, the dynamic pressure decreases and the static pressure increases. Inside the secondary curve cavity between the linear even flow barricade and the output grid, an even flow field is formed with even distribution of wind height and width and meeting wind speed requirement for ventilation exchanging.

Description

technical field [0001] The invention relates to a dynamic displacement ventilation and air supply device, which belongs to the technical field of HVAC. Background technique [0002] Displacement ventilation is a new air-conditioning ventilation method. Compared with the traditional mixed ventilation method, this air supply method can obtain higher air quality and better thermal comfort in the indoor work area, and has higher ventilation efficiency. Therefore, it has been widely used in industrial buildings, civil buildings and public buildings. Displacement ventilation is the most widely used in the Nordic countries, about 50% of industrial ventilation systems use displacement ventilation, and about 25% of offices use displacement ventilation systems. At present, some domestic projects have begun to adopt displacement ventilation system. [0003] As for displacement ventilation, the existing technologies and products at home and abroad are mostly passive. This traditional...
