VRF/VRV air conditioning explained
By David Otieno, Senior ICT Consultant 1 min read
Variable refrigerant flow systems serve many rooms from shared outdoor units, adjusting capacity to demand.
Variable refrigerant flow (VRF) — also called VRV — systems are common in offices, hotels and hospitals.
How they work
One or more outdoor units connect to many indoor units, varying refrigerant flow to match each room's demand.
Benefits
- Individual control per room or zone.
- Efficient operation at partial load.
- Flexible layouts.
Considerations
Design by qualified engineers, quality installation and refrigerant piping, and regular maintenance.
Smart control
Central controllers and building management integration allow schedules and monitoring.
Plan maintenance access
Indoor units in ceilings, outdoor units on roofs and long refrigerant runs all need safe access for servicing. Agree maintenance responsibilities and response times for faults, especially in guest rooms, wards and server rooms.
