VRV/VRF systems control each zone separately and can run efficiently, but only if the pipe design, refnet selection and commissioning are done carefully.
Scope
- System design: zoning, outdoor and indoor unit selection, and checks against the manufacturer's limits on pipe length and height difference.
- Revit modelling, so refrigerant and drain routes are coordinated with the structure and other disciplines.
- Installation of copper piping, brazing under nitrogen purge, refnets, insulation and control wiring.
- Commissioning: pressure test, vacuum, additional refrigerant charge and test run.
- Centralised control and integration with other systems if the facility team needs it.
Who it is for
Offices, campuses and government facilities with many zones and different operating hours.
