Variable air variable refrigerant flow (vavrf)

Abstract

The present disclosure describes various embodiments of a new HVAC system and apparatuses (and related methods) that combine the efficiencies of VRF and VAV systems. An exemplary system comprises a plurality of indoor units located in different zones of a building, each comprising a damper operable to modulate airflow through the indoor unit into a building space and a valve operable to modulate a flow of refrigerant through the indoor unit; an air handling unit having a supply fan that is configured to generate the airflow that is received by the plurality of indoor units; and a controller unit operable to control the damper and the valve simultaneously for each of the plurality of indoor units, wherein the controller unit is operable to control the supply fan and an amount of airflow generated by the supply fan.
