Airstage™ (VRF Systems) V-III TROPICAL Series
Excellent energy saving
Heat pump inverter type realizes the highly energy saving air conditioning for individual cooling and heating operation by all inverter technology for seasonal efficiency.
High design flexibility for various building air conditioning
High design flexibly meets the various needs of high-rise building air conditioning such as outdoor unit roof top concentrated installation and each floor installation by large capacity combination, sufficient connection capacity, and high static pressure design.
Easy installation and maintenance
The flexible communication method and piping connections makes installation and maintenance easy even for large systems.
High ambient operation design
Possible to operate cooling up to 52ºC outdoor temperature
Energy saving technology that boosted operation efficiency
Powerful large propeller fan
By using CFD*1 technology, a newly designed fan achieves high performance and low noise operation.
- CFD = Computational Fluid Dynamics
3 phase DC fan motor
Efficiency is substantially improved by high efficient motor with sophisticated driver control. In addition, low noise is realized by DC fan motor.
Subcool heat exchanger
High Heat Exchange efficiency is achieved by using an internal projection shape double pipe construction.
Sine-wave DC inverter control
High efficiency is realized by adoption of reduced switching loss IPM.
