Air Economizer High Limit Strategies

In this video, we break down key U.S. climate zones and show how conditions like hot-humid (Zone 1A – Miami), mixed-humid (Zone 3A – Atlanta), dry climates (Zones 1B–5B – Denver, Phoenix), and humid northern regions (Zone 5A – Chicago) impact HVAC design and economizer strategies.

You’ll see clear visual diagrams that illustrate the differences in dry vs. humid regions, coastal vs. inland climates, and how these affect building cooling strategies, energy efficiency, and sensor placement.

✅ What you’ll learn in this video:
The difference between humid and dry climate zones
Why sensor accuracy and placement matter for economizers
How climate impacts dry bulb vs. enthalpy control
Real-world examples from cities like Miami, Atlanta, Denver, and Chicago
Whether you’re an HVAC engineer, contractor, or student, this guide will help you better understand ASHRAE climate zones and how to design systems that balance energy savings, comfort, and reliability.
