Our Technology: Quattro™ Technology
Midea's Quattro™ Technology, powered by the Genius Core Energy Chip, utilizes a Precise-control Inverter Deduction Algorithm. This system reduces energy loss by enabling more precise signal reception, accurate data processing, and prompt delivery of instructions to the compressor. This results in more stable operation and a super-smooth inverter frequency variation, ensuring consistent room temperature without noticeable fluctuations.
Key Technology Benefits:
- Up to 71% Ultra Energy Saving.
- Flash Cooling/Heating in 6 seconds.
- Comfort within ±0.5°C stable temperature.
- Superior operation from 60°C to -30°C (High Ambient Cooling/Heating).
The Full DC Inverter System enhances energy efficiency by 20% compared to normal AC inverters.
Internal components include:
- Sine-wave DC inverter control.
- Rear-earth magnet motor.
- IPM DC Fan Motor.
These contribute to a Vector Shaped Motor design for smooth movement and high efficiency, contrasting with conventional motors that may be harder moving and less efficient.
The Perfect Multi Room Solution
Midea's multi-split systems are designed for flexible installation, allowing one outdoor unit to connect with up to 6 indoor units, each with independent control. This setup maximizes efficiency and comfort by enabling users to heat or cool only the rooms they need, leading to significant energy cost reductions.
Key Features:
- Higer Energy Efficiency under Partial load: Up to 30% less energy consumption when only a part of rooms require air conditioning.
- Bionic Blower Wheel and Improved Air Duct: Based on natural models, Midea's fan blade design and optimized air duct effectively reduce airflow resistance and noise, delivering the same airflow volume with 30% less energy consumption.
- V-PAM (Vector + I-PAM) Inverter Control: Enhances compressor speed and efficiency by reducing magnetic flux effects, leading to higher performance and enabling miniaturization.
- Twin-Rotary Compressor: Ensures low vibration and noise due to its 180° symmetrical balance.
- Inner Groove-Tube: Features a densely serrated copper design to enlarge the heat exchange area, increasing heat transfer efficiency.
Customise Choice: Indoor Unit Types
Midea Inverter Multi Split Systems offer a choice of 4 indoor unit types, providing endless combination possibilities:
- Wall Mounted Split System: Discreet yet powerful performance with Turbo Function for rapid cooling/heating. Wi-Fi control via the Midea Mobile App allows remote adjustments.
- Ducted: Designed for quiet operation, hidden within bulkheads or ceiling cavities for a seamless look.
- Compact Cassette: Low-profile design delivering 360° airflow, ideal for open-plan living areas.
- Floor Console: Features a dual-outlet design for fast temperature adjustments. Can be wall-mounted or floor-standing and offers convenient Wi-Fi control via Android or Apple apps.
Outdoor units feature capacities from 5kW to 18kW and can be paired with up to 6 indoor units.
Flexible Installation
Midea's multi-split system allows one outdoor unit to connect with up to 6 indoor units, each with independent control. This flexible setup not only saves space but also reduces energy costs by letting you heat or cool only the rooms you need.
Automatic Wiring/Piping Correction
Midea multi-split units simplify installation by automatically correcting wiring and piping connections. Technicians simply press a "check switch" after installation, and the system automatically verifies and corrects connections, avoiding trial operations.
Diagram Description: A diagram illustrates the "BEFORE" and "NOW" states of wiring connections for an outdoor unit and two indoor units. The "BEFORE" state shows potential incorrect connections marked with 'X', while the "NOW" state shows all connections correctly identified with checkmarks '✓', indicating successful automatic correction.
