Centralised AC and VRF
VRF AC Outdoor Unit Location Planning
Compare rooftop and service-ledge locations for VRF outdoor units before finalising pipe routes, airflow and maintenance access.
Choosing a rooftop, service ledge or equipment yard for the VRF outdoor units affects the entire HVAC layout. A location that looks convenient on a floor plan can add long pipe routes, restrict service access or cause discharged hot air to return to the equipment. Compare locations with the architect and equipment selector before issuing the final drawings.
Measure the whole refrigerant route
Mark the path from each candidate outdoor unit location through shafts and branches to the indoor units. Record actual route lengths and elevation differences. The VRF supplier should check the proposed model’s limits and pipe sizes, including any limits after a branch. Compare this work against the available riser space and access.
Draw clearance, lifting and service zones
- Check the manufacturer’s intake and discharge clearances against walls, screens and neighbouring units.
- Coordinate structural support, access for replacement and the route for lifting equipment.
- Confirm where isolators, walkways, drainage and guards are required in the project design.
Compare options before the order is placed
Ask the project team to compare roof and ledge options using the same equipment schedule, zones and assumptions. Record any unresolved design input, such as a building-management restriction or façade screen. Confirm the chosen location on the issued coordination drawings so other trades can reserve the required space.
