Design Inverter: The Perfect Combination of Style, Innovation, and Efficiency

The Design Inverter series was developed at the request of the Italian branch of Mitsubishi Electric, where product aesthetics play a crucial role in commercial success. However, its refined design does not compromise the strict standards of energy efficiency and noise reduction – ensuring this range remains a leader in its class.

Key Benefits:

• Ultra-quiet operation – noise levels as low as 19 dB(A) (for MSZ-EF22/25VGK models), combined with high energy efficiency.
• Advanced aerodynamics – the innovative air distribution system ensures optimal airflow for both cooling and heating.
• Enhanced features – MSZ-EF VGK indoor units come equipped with a bactericidal silver-ion filter, a backlit remote control, and a built-in Wi-Fi module.

Silent Mode

The MSZ-EF series includes a super-quiet mode, reducing noise levels to just 19 dB(A). This makes it an ideal choice for bedrooms, children's rooms, and other spaces where quiet operation is essential.

"I save" Function

This mode allows users to store two personalized settings:

For cooling (or the energy-saving "ECONO COOL" mode).

For heating.

Pressing the "I save" button instantly switches the system to the pre-set temperature, fan speed, and airflow direction. Pressing it again restores the previous settings.

Advantages:
✅ Quickly switch to an energy-saving mode, by increasing the cooling temperature by 2–3°C or lowering it in heating mode.
✅ Can be used as background heating, with a minimum temperature of +10°C.

Automatic Mode

The system automatically selects heating or cooling based on the difference between the set and actual room temperature. Switching occurs when the temperature difference exceeds 2°C and persists for more than 15 minutes.

Low Power Consumption in Standby Mode

Even when the air conditioner is turned off, it may still consume energy. However, MUZ-EF VG models are equipped with a special circuit system that disconnects power lines during idle periods, significantly reducing standby energy consumption.

Bactericidal Silver-Ion Filter

The MSZ-EF VGK filter contains silver nanoparticles, known for their disinfecting properties:
✔ Prevents bacterial growth (bacteriostatic effect).
✔ Destroys harmful microorganisms by disrupting their metabolism (bactericidal effect).

The effectiveness of this technology has been confirmed by studies from the Japanese "BOKEN Quality Evaluation Institute".

For optimal performance, it is recommended to replace the filter once a year (replacement part number: MAC-2370FT-E).

Conclusion

The Design Inverter series blends elegant design, advanced technology, and eco-efficiency, making it one of the best choices on the air conditioning market.
