AIRSTAGE™ 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.

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 intake port with a slanted-corner air-inhaling structure

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