This value is based on the case where the outdoor unit is located above the indoor unit.
If the outdoor unit is located underneath the indoor unit the level difference is a maximum
of 40m. 
The maximum actual piping length between the indoor unit and the first branch is 40 m.
Equivalent pipe length between outdoor and indoor units 175 m 
The BS unit can be located anywhere between the indoor unit and outdoor unit, 
if installing after the first branch
(REFNET JOINT or HEADER) , the piping limit is less
than 40m. 

In conventional systems that use water, the size of the pipes had
to be calculated depending on the amount of water used. In the
VRV system, however, Daikin's advanced compressor
technology eliminates the need for time-consuming piping
calculations and greatly reduces design time.
Long Piping Design
Can Be Installed for Each Floor
The refrigerant piping length between the indoor unit and
outdoor unit in one system can extend up to 150 meters and the
difference in height can be as great as 50 meters. These
generous allowances make it possible to put all the outdoor
units on the rooftop in a 15-story building. The difference in height
between indoor units in the same system can be as much as 15
meters, thus making it possible to cover four or five stories with a
single system.
Systems Requiring a Mix of Cooling and Heating Can Be Easily Designed
When cooling and heating must be simultaneously performed in
the same building, until now a 4-pipe fan coil system had to be
used. The VRV system Heat Recovery Series, however, satisfies
these needs with ease of design and installation.
Air Refreshing Treatment (Heat Reclaim Ventilation: HRV)
Lightweight Outdoor Units Short Design Times
Lightweight outdoor units featuring minimized vibrations do not
require floor reinforcement as do conventional systems.
The HRV system exchanges heat between the
supplied air and exhausted air in order to bring
the outside air closer to the indoor temperature
and humidity conditions, thus allowing
ventilation without increasing the cooling and
heating load. And it can save not only running
cost but also initial air conditioning system's
cost because the smaller ones can be selected. 
The HRV system interlocks with the operation of
the VRV system, thus eliminating the need for a
dedicated HRV remote controller and
simplifying installation and wiring operation. The
central control unit is common to the VRV, thus
helping achieve the total control and
management of air conditioning and ventilation.
Wide Range of Control Systems
Using regular wired or wireless remote controllers, various control
systems can be achieved including double remote control, group
control of up to 16 units and interlocked control with HRV.
By flexibly combining the central controller, on/off controller and
schedule timer, a versatile central control system can be easily
constructed to control up to 128 indoor units.
Our large-scale air conditioning management system consists of
the intelligent Manager ECO 21, which allows BMS*-level
monitoring and control simply using a personal computer, or the 
BACnet Gateway / DMS-IF (for LONWORKS
®
), which connects
air conditioning system to a BMS to perform monitoring and
control.

Intelligent touch Controller is a simplified but highly advanced
central control air conditioning management system that gives
complete control of your air conditioning equipment.
Daikin's VRV systems include indoor and outdoor units available in a wide variety of models for
all sizes of buildings and installation conditions. Long refrigerant piping lengths and other
features put few restrictions on design for greater flexibility in meeting the needs of the building.
Since the external hydrostatic pressure of the outdoor unit fan motor is 6 mm H2O, an outdoor unit can
be placed on each floor using short-discharge ductwork.
Lineup of heat pump types is 5 to 48 HP, and heat recovery types
is 8 to 48 HP, both in 2 HP increments*. Indoor units consist of 10
types with a total of 63 models. This wide selection of models
makes it possible to build a system that perfectly suits the
customer’s requirements.
