= Variable Refrigerant Volume
Variable: The system responds depending on the required
capacity.
Refrigerant: Direct expansion system.
Volume: The refrigerant volume is regulated by an electronic
expansion valve in each indoor unit...

The VRV system has realized the REFNET piping system to facilitate simple piping construction through original refrigerant control. As a result, not only piping design is drastically simplified but also piping extending in a building is drastically curtained. Dedicated joints and headers are prepared for branch portions where construction is said difficult. Both design and construction are simplified to realize easiness of level same as that of water piping in a central air conditioning system.
Further, sue of the DAIKIN piping/wiring distribution diagram preparation software will enable simple check of piping diagrams.
