VRV-WII

The water-cooled VRV-WII uses

water as its heat source and since

there are no limitations on water

piping length, is eminently suitable

for application to tall multi storey

or large buildings. Considerable

flexibility is available within the

refrigerant circuit since up to 120m

actual piping length and 50m* (if

the VRV-WII is above the indoor

units) in height can exist between

the VRV-WII and indoor units.

Water piping does not intrude on

the occupied spaces, so there are

no leakage problems.

VRVIII

VRVIII offers an extended piping

length of 165m (190m equivalent

piping length) with a total system

piping length of 1,000m.

In case the outdoor unit is located

above the indoor unit the height

difference is 50m standard. It can

be extended to 90m*

In case the outdoor unit is located

below the indoor unit, the height

difference is 40m standard. Height

differences up to maximum 90m

are possible*.

After the first branch, the longest piping length can be a maximum of 90m provided that the difference

between the longest piping length and the shortest piping length is a maximum of 40m.

* For more information, please contact your local Daikin dealer.
