An air duct cross fitting

Abstract

The invention provides an air duct cross fitting used in a new exhaust ventilation system. The cross fitting can minimize the airflow loss in the cross duct, and at the same time solves the problem of intersecting air duct occupation in the new exhaust ventilation system of a building. The problem of building vertical height space.

Description

Technical field [0001] The present invention relates to a wind tube cross pipe, and specifically, a wind tube cross pipe for a new exhaust system, belonging to the technical field of civil engineering HVAC. Background technique [0002] In the building ventilation ventilation system, there is often a problem of vertical cross-stroke of new wind tubes and exhaust wind tubes. The usual way is to arrange the new wind tubes and exhaust pipes in the vertical direction, since the duct size is relatively large. The cross of the wind tube will occupy a large vertical height, usually take a high level of highlighting to ensure that the level is high, thereby causing an increase in the height of at least 200 mm per layer, making the cost of civil construction. [0003] Especially in some civil buildings such as high-level office, hotels, new wind and drainage often use new wind ventilation to recycle drain energy, new wind main wind pipes and exhaust main wind tubes are placed in parallel ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the local resistance of the crossing of air pipes in the new exhaust and ventilation system of the building increases and the vertical space of the building is occupied, especially in places such as offices and hotel buildings where fresh air ventilators are used, the present invention provides a The air duct cross fittings of the wind ventilation system, which can minimize the airflow loss in the cross ducts, and also solve the problem that the cross ducts of the new building exhaust and ventilation system occupy the vertical height space of the building
