CAV (constant air volume system)

When the load of the air-conditioning area changes, the air supply temperature will be changed to meet the indoor load and meet the requirements of maintaining the indoor temperature in the comfort zone. Commonly used central air conditioning systems are AHU (air conditioner) and cold water pipe system (FCU system). Both of these are generally supplied with constant air volume (CAV) to the air-conditioning area. In order to cope with the variation of the indoor partial load, the AHU constant air volume system uses the variable temperature air supply of the air conditioner to deal with, and the general FCU system uses the cold water valve ON/OFF. Control to adjust the supply air temperature.
