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 lower end of the operating temperature range in heating has been extended from –15°C to –20°C.
The extended maximum piping length gives more flexibility
when designing the system.

New compressor technology eliminates the need for piping
calculations, which shortens the time needed for design.

Layout changes can be made easily because the capacity of the
indoor units can be up to 130% that of the outdoor units.
Outdoor units can be placed on the roof where they have no
effect on the design of the building interior.
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.

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 lift.

Units can be installed on each floor.

The pipes are few in number, making layout simpler.
Inspection after installation is straightforward.

Operates over a broad temperature range
Provides superior design flexibility
Enhances ease of use
Delivers ultimate reliability
Simplifies installation
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.
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.
Using the HRV for ventilation dramatically boosts energy
efficiency.
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
Saves energy
Conserves space
Offers a wide selection of models
