Variable Air Volume (VAV) is a type of HVAC system that maintains a constant temperarture while varying the airflow in order to heat or cool buildings. This is in contrast to Constant Air Volume (CAV) systems, thaten-USTelligent Community 12https://community.element14.com/products/manufacturers/superior-sensor-technology/b/blog/posts/lowering-hvac-energy-consumption-with-vavWed, 10 Sep 2025 17:04:03 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:fc1fc312-a66a-43c1-a43c-f9e1f21d3f78dougw0<p>It sounds like it would be useful to have 2 air temperature sources available to provide airflow even when there is no need to change the room temperature. This would avoid cooling and heating the same air. (Air flow is needed just to purge CO2 generated by people)</p><img src="https://community.element14.com/aggbug?PostID=29203&AppID=438&AppType=Weblog&ContentType=0" width="1" height="1">
