VRV SYSTEMS

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.

Individual control
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.

Other advantages
Saves energy

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.
Conserves space

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.
Simplifies installation

The lightweight, compact units can be transported using a regular lift.
Units can be installed on each floor.
The pipes are narrow and few in number, making layout simpler.
Inspection after installation is straightforward.
