    en.wikipedia.org/wiki/Constant_air_volume

    In a simple CAV system, the supply air flow rate is constant, but the supply air temperature is varied to meet the thermal loads of a space. [1] Most CAV systems are small, and serve a single thermal zone. However, variations such as CAV with reheat, CAV multizone, and CAV primary-secondary systems can serve multiple zones and larger buildings.

  7. Automatic balancing valve - Wikipedia

    en.wikipedia.org/wiki/Automatic_balancing_valve

    Although the capital costs of installing a constant flow system are relatively low, the manual balancing required is time-consuming, complicated, laborious and system is inefficient. This results in higher running costs and subsequently resulting in higher CO 2 emissions. Since most air-conditioning and water distribution systems only reach ...
