VRV/VRF System Maintenance
Expert Care for Multi-Split Systems
Variable Refrigerant Volume (VRV) and Variable Refrigerant Flow (VRF) systems are sophisticated HVAC solutions used in commercial buildings. These systems require specialized knowledge and equipment for proper maintenance.
What is VRV/VRF?
VRV (Daikin’s trademark) and VRF (generic term) systems connect multiple indoor units to one or more outdoor units through a single refrigerant loop. This allows:
- Individual zone control - Different temperatures in different rooms
- Energy efficiency - Only active zones consume power
- Flexible design - Mix of cassette, ducted, and wall units
- Heat recovery - Some zones can cool while others heat
