What are the advantages of a VRV System
over central air conditioning systems?

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
• 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 largescale air conditioning system with a single piping circuit

Offers a wide selection of models
• Lineup of heat pump types and cooling only are 5 to 54 HP, and both in 2 HP increments*. Indoor units consist of 14 types with a total of 79 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 200% 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 few in number, making layout simpler.
• Inspection after installation is straightforward.
