Embodiment 1

[0031] Example 1 An air duct intersection fitting used in a new exhaust ventilation system. The size of the fitting is designed according to the actual application of the project and verified through the application of specific HVAC projects. The relevant parameters and efficacy data are shown in Table 1. .

[0032] Such as Figure 1-5 As shown, a cross-section of the air duct used in the new exhaust and ventilation system, the cross section of the external pipe of the main air duct expansion pipe 1 and the external pipe of the branch air pipe 2 are rectangular, and the main air duct expansion pipe 1 is One side is expanded, and the expanded part is made up of expanded parts 3-1 and 3-2, expanded joint part 3-3, and the other side is not expanded.

[0033] The pipe fittings in this embodiment include main air pipe expansion pipe 1, branch air pipe 2, reducing pipes 4-1 and 4-2, tuyere flanges 5-1 and 5-2, tuyere flanges 6-1 and 6- 2. The two ends of the main air pipe expansi...

Abstract

The invention provides a wind pipe crossed pipe fitting of a new exhaust air exchange system. According to the crossed pipe fitting, airflow losses in crossed wind pipes can be reduced to the maximum, and meanwhile the problem that wind pipes of the new exhaust air exchange system of a building occupy the vertical height space of the building is solved also.

Description

technical field [0001] The invention relates to an air duct intersecting fitting, in particular to an air duct intersecting fitting used in a new exhaust and ventilation system, and belongs to the technical field of civil engineering heating and ventilation. Background technique [0002] In the building ventilation system, there is often the problem that the fresh air duct and the exhaust duct vertically intersect. The usual method is to arrange the fresh air duct and the exhaust duct vertically. Due to the relatively large size of the duct , The crossing of air ducts will occupy a large vertical height, and the method of increasing the floor height is usually adopted to ensure the clear height of the floor, which causes the height of each floor to be increased by at least 200mm, which greatly increases the cost of civil engineering. [0003] Especially in some civil buildings such as high-rise offices and hotels, fresh air and exhaust air often use fresh air ventilators to ...
