01 / UNDERSTAND THE SYSTEM
VRV & VRF systems in context.
Variable refrigerant flow systems connect multiple indoor units to an outdoor system and adjust refrigerant flow to suit demand. VRV is Daikin’s name for its VRF technology.
Individual rooms share one coordinated refrigerant system. Fault diagnosis needs to consider the network, not only the room with the complaint.
Outdoor modules
The outdoor equipment responds to combined demand, within the limits of its design and controls.
Pipework & communication
Refrigerant branches, wiring and addressing link the equipment. Manufacturer-specific requirements apply.

02 / SCOPE & CONDITION
What we look at.
| Area | What matters | Why it matters |
|---|---|---|
| One room affected | Indoor unit, controller, drainage and local conditions | Record whether the other rooms operate normally. |
| Many rooms affected | Outdoor system, shared controls and supply | Capture outdoor and indoor alarm information. |
| Replacement planning | Compatibility, pipework and refrigerant | New and existing equipment must form an approved combination. |
Work that can be included
- Indoor unit and outdoor module servicing
- System alarms and communication faults

04 / COMMON QUESTIONS
A little more clarity.
Are VRV and VRF different systems?
VRF describes the general technology; VRV is a Daikin trademark. Exact capabilities and compatibility depend on the manufacturer and model.
Can any indoor unit connect to a VRF outdoor unit?
No. Compatibility depends on the manufacturer, system generation, capacity combination and control requirements.
Will every zone have independent heating and cooling?
Not on every system. Simultaneous heating and cooling requires a suitable heat-recovery arrangement; capabilities depend on the model.
