The VRF dividing line for Midea multi-split outdoor units
Outdoor units serving two and four indoor units were classified under the same GTIP, with the records focusing on why they do not qualify as variable-refrigerant-flow systems.
01
Expert assessment
Although both units can serve several independent indoor units, the pipe layout, absence of a common main refrigerant line and location of the electronic expansion valve in the outdoor unit were assessed together. Indoor-unit count alone does not establish VRF character.
02
Precedent warning
Do not transfer the result to models with different pipe topology, valve location, simultaneous operation or network control.
