Embodiment 1

[0049] Such as Figure 1-10 As shown, the present embodiment proposes a low-Re number high-efficiency air supply device for use in cross-shaped building corridors. The center is a dot, which is connected around the fixed structure of the blade to form a circular low-Re number high-efficiency air supply device around the fixed structure of the blade; there is a gap between the adjacent blades, and the gap is used for wind;

[0050] Each gap angle value y for air outlet satisfies:

[0051]

[0052] Among them, y 0 is a constant, the value is 1.07125±0.07089;

[0053] w is a constant, the value is 0.51152±0.07169;

[0054] x c is a constant, the value is 0.69813±0.01346;

[0055] A is a constant with a value of -0.40727±0.0918;

[0056] A two-dimensional coordinate system is established with the axis center of the blade fixed structure as the circle point, the horizontal positive direction of the two-dimensional coordinate system is specified as 0°, n is the nth air outl...

Abstract

The invention provides a low-Re (Reynolds)-number efficient air supply device for a corridor. The low-Re-number efficient air supply device comprises a blade fixing structure and a plurality of blades, wherein all the blades take the axis of the blade fixing structure as a point, and are connected around the blade fixing structure to form a circular air supply device; a gap is formed between two adjacent blades, and the gaps are used for discharging air; and all the gaps form four air outlets and four air outlets. By the device, the air supply of an air conditioner of a cross-shaped building gallery space can be more uniform, and the wind speed at different positions and the air supply accessibility of the whole space can be guaranteed.

Description

technical field [0001] The invention belongs to the field of ventilation and air conditioning, and relates to the improvement of air outlets in ventilation and air conditioning rooms, in particular to a low-Re number high-efficiency air supply device for corridors. [0002] technical background [0003] With the acceleration of the urbanization process in our country, the architectural plane forms are increasingly diversified and individualized. There are more and more irregular building structures, such as cross-shaped buildings with complex plane shapes and cross-shaped passages in buildings. Especially cross-shaped passages are commonly found in school classrooms, libraries, shopping malls, etc. Good indoor air quality contributes to people's health. Therefore, a good HVAC design for the cross-shaped building is an important factor to ensure the thermal comfort and air quality of the human body in the cross-shaped building space. It is worthy of attention to study the ai...
