VRF Systems V-III Series

System overview

Excellent energy saving

The all-inverter heat pump provides highly energy-efficient air conditioning for individual cooling and heating operation all year round.

Great design flexibility for placement in any building

Design flexibility meets the diverse installation needs of high-rise buildings for air conditioners, such as rooftop, concentrated installation of outdoor units combined with individual floor installation of indoor units. This flexibility is achieved by large-capacity combination, sufficient connection capacity, and high static pressure design.

Easy installation and maintenance

The flexible communication method and piping connection make installation and maintenance easy even for large systems.


Outstanding efficiency in real-world operating conditions

The use of our proprietary heat exchanger structure and highly efficient DC twin compressors achieves the best-in-class coefficient of performance (COP) in every combination.

3-phase DC fan motor

The use of a DC fan motor with sophisticated driver control improves energy efficiency substantially. In addition, this motor operates quietly.

Subcooling heat exchanger

The double-pipe structure with internal projections achieves great heat-exchanging efficiency.

Sine-wave DC inverter control

The use of a motor with an intelligent power module (IPM) reduces switching loss and achieves great efficiency.

High-efficiency, large-capacity DC inverter compressor

A high-efficiency, large-capacity DC twin-rotary compressor offers excellent intermediate capability.

4-face heat exchanger

The 4-face heat exchanger increases the effective surface area and significantly improves heat-exchanging efficiency.

Front slanted-corner air-intake port

When multiple outdoor units are installed, the uniquely shaped front intake improves the airflow into the heat exchanger.
