VAV Diffusers in HVAC: A Basic Guide
A VAV diffuser, short for Variable Air Volume diffuser, is a part of some heating and cooling systems. It controls how much air goes into a room. Unlike normal diffusers that always send the same amount of air, a VAV diffuser can change this amount. So, if a room needs to be cooler, it lets in more cool air. This helps keep the temperature just right in each room and can save energy. VAV diffusers are especially handy in big buildings or offices where different rooms might need different temperatures.
