Unique piping and wiring systems and lightweight, compact indoor units make it possible for just
a few people to install a VRV system quickly and easily. The Auto Address Setting function and
the Auto Check function for piping and wiring errors allow anyone with just the ability to install
regular direct expansion type air conditioning equipment to perform a highly reliable installation.
Reduced Piping and Cost
Super Wiring System
Auto Address Setting Function
The address of each indoor unit is set automatically at the same
time they are connected, thus eliminating the need to manually
set each address. Address setting for central control can be
performed easily from the remote controller of an indoor unit.
Sequential Starting
By employing D -net, systems on the same power line will be
started sequentially. This holds down the starting current,
allowing the capacities of breakers to remain small (possible up
to 100 HP).
Four-Way Wiring and Piping Connection
Check Function for Connection Errors of Wiring and Piping
Mistakes in piping or wiring in the system can be checked via
lamps on the printed circuit board of the outdoor unit.
Wiring can be fed from the front panel, both left and right side
panels or bottom panel of the outdoor unit.
Piping can be fed from 4 directions, front, both left and right or
bottom of the outdoor unit.
These features increase installation flexibility, minimizing the
space required for installation and simplifying maintenance of
the wiring and piping.
Simple Wiring
Daikin's advanced REFNET piping system makes installation
easy. Only two* main refrigerant lines are required in one system,
and the strainers, stop valves, two-way and three-way valves,
used in conventional water piping systems are not required.
Thanks to the REFNET piping system and electronic expansion
valves, imbalances in refrigerant flow between units is greatly
reduced even though small-diameter piping is used. The small-
diameter piping is also easy to handle and requires less piping shaft
space. (* Three in the case of heat recovery type.)
The REFNET Joint and REFNET
Header (both optional) reduce the
amount of work involved in
installation and increases the
reliability of the system.
A Super Wiring system is used to enable the shared use of the
wiring between indoor and outdoor units and the central control
wiring. A high-level central control system can be achieved via a
relatively simple wiring operation. Even when retrofitting with a
central control system, all that is required is to connect the central
control unit to the outdoor units.
Two-wire multiplex transmission system makes it
possible to connect multiple indoor units to one
outdoor unit with one 2-core wire, thus simplifying
the wiring operation.
