VRF loops are not like other loops in DesignBuilder HVAC. They consist simply of a single VRF outdoor unit connected to one or more VRF indoor units through a dotted line.
VRF indoor units are placed within HVAC zones like other zone forced air units.
There is no data associated with the VRF loop itself - it mainly serves as a container for the VRF outdoor unit and the connections to the indoor units.
