Learn the fundamentals of HVAC design, from cooling-load calculations and system selection to airflow, duct sizing, equipment selection and commissioning. This practical beginner-friendly guide explains the complete design roadmap and introduces Nexora resources that help you strengthen your HVAC knowledge and calculation skills.

Learn how to design a chilled-water piping system step by step—from cooling-load and flow-rate calculations to pipe sizing, pressure-loss analysis, pump-head selection, valves, controls, insulation and commissioning. Includes practical equations, diagrams, tables and a complete worked example for HVAC and MEP engineers.

HVAC duct design and sizing ensure that the correct amount of conditioned air reaches each space efficiently. Proper duct sizing balances airflow, velocity, and pressure loss to maintain comfort while minimizing energy consumption. Using methods like the Equal Friction Method and accurate airflow calculations helps engineers design duct systems that deliver reliable performance and optimal HVAC efficiency.
