Duct Components: Core Composition and Selection & Installation Guide for Ventilation and Air-Conditioning Systems Duct components are key elements in ventilation and air-conditioning systems that enable air transport, distribution, and functional control. Their design, selection, and installation directly determine system efficiency, safety, and stability. This article systematically introduces the classification, characteristics, selection principles, and installation and maintenance key points of duct components. I. Definition and Core Classification of Duct Components Duct components include functional elements such as air outlets, valves, exhaust hoods, wind caps, inspection doors, and measuring holes. Together with ducts and fittings (e.g., elbows, tees), they form a complete air distribution system. Classified by function: - Air Outlet Category: Includes supply air outlets, return air outlets, and exhaust air outlets, which need to meet requirements for air flow ...

Complete Guide to Central Air Conditioning Ventilation Duct Installation: Detailed Explanation of Specifications, Methods and Spatial Layout The professional installation of central air conditioning ventilation ducts is crucial to ensuring the efficient operation of the system and improving indoor comfort. The installation process requires comprehensive consideration of factors such as location selection, installation methods, technical specifications, and spatial layout. Negligence in any link may affect the final result. 1. Selection of Installation Location and Supply/Return Air Methods The position of ventilation ducts should be carefully planned to avoid direct airflow to areas where people frequently stay, such as bed heads, sofas, and office seats, to prevent discomfort caused by direct airflow. Meanwhile, air outlets should not be directly facing doors or windows, as this may disrupt indoor air distribution and potentially cause condensation on glass. There ...
