A VRV system provides considerable savings on energy, costs,
and space requirements. The VRV's innovative inverter technology
ensures the kind of performance required by building owners in
every stage of operation. And the unique REFNET piping system
and compact, lightweight unit design give flexibility in system
planning and quick and easy installation.
Conventional systems air condition a building as a whole, whereas
the VRV system air conditions each room individually. Hence it
is ideal for the constantly changing occupancy of a typical building.
Even further, precise level control is possible that reacts to
the exact conditions in each room. Individual control promotes
a far more economical and efficient system.
The heat recovery system supports separate heating and cooling
in different rooms, making the system ideal for the constantly
changing occupancy of a typical building.
Using the HRV for ventilation dramatically boosts energy efficiency.
Space efficiency is enhanced by the compact size of the individual
units, the long maximum piping length, and the ability to realize
a large-scale air conditioning system with a single piping circuit.
Offers a wide selection of models
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.
* Except for 5 HP
Operates over a broad temperature range
The lower end of the operating temperature range in heating has
been extended from –15°C to –20°C.
Provides superior design flexibility
The extended maximum piping length gives more flexibility when
designing the system.
Layout changes can be made easily because the capacity of the
indoor units can be up to 130% that of the outdoor units.
New compressor technology eliminates the need for piping calculations,
which shortens the time needed for design.
Outdoor units can be placed on the roof where they have no effect
on the design of the building interior.
Enhances ease of use
Units are designed to operate quietly, and are also equipped
with a function for silent operation especially at night.
The controller is easy to operate and has many useful functions.
Units can be controlled in each individual room.
Delivers ultimate reliability
The self-diagnostic system identifies problems within the system
quickly and accurately.
The Auto Restart function ensures that operation is restored with
the previous settings even if the power has been shut off.
Units are controlled in each individual room, so local malfunctions
does not cause the entire system to shut down.
The lightweight, compact units can be transported using a regular
Units can be installed on each floor.
The pipes are narrow and few in number, making layout simpler.
Inspection after installation is straightforward.
