Types of Air Terminals in HVAC

🌬️ Types of Air Terminals in HVAC: A Practical Guide for Designers and Contractors Air terminals are the final delivery points of conditioned air in HVAC systems. Whether you're designing for comfort, aesthetics, or performance, selecting the right air terminal is crucial for achieving optimal airflow, temperature control, and acoustic performance. In this article, we’ll explore: 🔍 What air terminals are and why they matter 🧭 Classification of air terminals 🛠️ Common types used in residential and commercial HVAC 📐 Selection criteria for air terminals 📊 Application tips for designers and contractors 🔍 What Are Air Terminals? Air terminals are devices that distribute conditioned air from the ductwork into occupied spaces. They regulate airflow direction, velocity, and volume, and often contribute to the room’s visual and acoustic comfort. They are typically categorized into: Supply air terminals : Deliver air into the space Return air terminals : Extract air b...

HVAC Duct Sizing Methods: Imperial & Metric Guide for Engineers.

📐 HVAC Duct Sizing Methods: Imperial & Metric Guide for Engineers Learn how to size HVAC ducts using Equal Friction, Velocity Reduction, and Static Regain methods. Includes formulas, velocity benchmarks, and ASHRAE-compliant tips in both Imperial and Metric systems. 🔍 What Is HVAC Duct Sizing? Duct sizing determines the dimensions of air pathways that deliver conditioned air throughout a building. Proper sizing ensures: Adequate airflow (CFM or L/s) Acceptable velocity (FPM or m/s) Minimal pressure loss Energy-efficient fan operation 📊 Common Duct Sizing Methods 1. Equal Friction Method Used for: Residential and commercial systems Goal: Maintain a constant friction rate across all duct sections Steps: Choose a friction rate: Imperial: 0.1 in.wg per 100 ft Metric: 0.8 Pa/m Use Ductulator/ Mcquay Duct Sizer or charts to find duct size for each airflow rate. Apply the same friction rate throughout the system. Formula: Imperial: Friction Loss = (Total...
