Daikin VRV - Air Cooled or Water Cooled

35
Air to air VRV systems make up the majority of
VRV installations This is due to the following:
» Ease of installation (no water system required)
» Less initial capital costs
However Water Cooled VRV can have
certain advantages:
» Greater energy efficiencies
» Localized CU installation
(reduced pipe runs)
These advantages come in to play
when the following are present:
» An existing chilled water loop
» Extreme ambient conditions
» An ability & desire to utilize a
local geothermal source

Factors that Benefit the use of VRV Water Cooled Series
Water Cooled VRV - Existing Water Loop
By utilizing an existing
water loop in the building,
the advantages of greater
energy efficiency can be
promoted without having
to offset capital costs.
In addition VRV Water
Cooled Series CUs are
usually located locally to the
area they are serving and
will typically attach to the
water loop already running
through the building. This negates the need to run copper piping
through risers to a remote plant space (be aware that VRV Water
Cooled Series CUs are internal mounting units).
