Features
New intelligent refrigerant control
Fujitsu General is proposing outdoor units equipped with refrigerant control function.
The refrigerant control operates with subtle control corresponding to the heat load of the room and offers a more comfortable environment. The refrigerant control can also provide increased energy savings.
* The improvements due to the control and the actual sine wave vary depending on the combination of the indoor unit and system operating conditions.
Efficiency in actual operating conditions
The use of our proprietary heat exchanger structure and high-efficiency DC twin-rotary compressors achieves the classleading coefficient of performance (COP) in every combination.
Space saving combination
Energy efficiency combination
* These specifications are determined by Cassette combination.
* Multiple outdoor units are not certified by Eurovent.
The energy-saving technology that boosted operation efficiency
1. Powerful large propeller fan
The fan uses CFD* technology to achieve both high performance and low noise operation.

- CFD: Computational Fluid Dynamics
2. 3-phase DC fan motor
The use of a DC fan motor with sophisticated driver control improves energy efficiency substantially. In addition, low noise is realized by the DC fan motor.
3. Sine-wave DC inverter control
High-efficiency is realized by the adoption of reduced switching loss IPM.
4. 4-face heat exchanger
The 4-face heat exchanger increases the effective surface area and significantly improves heat-exchanging efficiency.
5. Subcooling heat exchanger
High heat exchange efficiency is achieved by using an internal projection-shape double-pipe construction.
6. High-efficient, large-capacity DC twin-rotary compressor
Large-capacity high-efficient DC twin-rotary compressor with excellent intermediate capability.
7. Front intake port (Corner cut air inlet structure)
In multiple outdoor unit installations, the unique front intake design improves airflow into the heat exchanger.
