VRF and VRV systems
Canonical HVACentric knowledge for commercial questions on this topic.
DIRECT ANSWER
Variable refrigerant flow systems connect multiple indoor units to shared outdoor equipment and use controls to vary refrigerant flow. Project review should cover zone loads, equipment combinations, piping design and limits, controls integration, ventilation, condensate, electrical work, refrigerant management, access, commissioning, training, and local service support. The system type does not remove the need for independent ventilation and code review.
