Occupancy-Aware Four-Way Cassette with Acoustic-Grade EEV Silencing Radar-Driven Demand Control Noiseless Refrigerant Routing and Seven-Step Fan Matching for the Modern Open Floor Plate

Occupancy-Aware Four-Way Cassette with Advanced Demand Control

Radar-Driven Demand Control, Noiseless Refrigerant Routing, and Seven-Step Fan Matching for the Modern Open Floor Plate

When open-plan spaces experience fluctuating occupancy throughout the day, traditional cassette systems waste energy on unoccupied zones while under-serving crowded areas. The Midea V8 Four-Way Cassette addresses this challenge with an integrated millimeter-wave radar module that continuously scans for human presence—automatically increasing output when rooms fill and reducing to setback mode when empty.

Combined with electronic expansion valve noise cancellation that eliminates refrigerant hiss at the panel, this unit redefines performance expectations for commercial VRF ceiling cassettes. The four-sector discharge geometry ensures comprehensive room coverage, while independent vane control allows customization for non-standard room layouts.

Seven discrete fan speeds provide precise airflow matching to real-time thermal conditions, and the complete digital drainage system—including monitored pump, anti-sweat logic, and water-level fail-safe—makes this the most intelligent ceiling unit in the portfolio.

Core Features

Omnidirectional Coverage: Four discharge vectors provide complete room conditioning from a single central mounting point, reducing the number of units required per floor.
Millimeter-Wave Occupancy Radar: Embedded sensor detects occupancy states with high accuracy, automatically transitioning between active comfort and energy-saving setback modes.
EEV Noise Elimination: Advanced control algorithm suppresses refrigerant flow noise, ensuring quiet operation without intermittent hissing.
Dual-Point Temperature Sensing: Combined readings from controller and unit chassis account for stratification and localized heat sources for more accurate climate control.
Per-Vane Independent Steering: Individual louver control allows customized airflow direction—redirecting air from unoccupied areas while maintaining output to occupied zones.
Seven-Step Fan Control: Precise airflow matching to actual thermal loads reduces both acoustic output and energy consumption during partial-load conditions.
Soft-Discharge Mode & Drain Protection: Draft-free ceiling-level air distribution with optional silver-ion drain pan for continuous bacteriostatic protection.

Application Scenarios

Scenario	Description
Open-Floor Commercial Offices	Radial coverage eliminates perimeter dead zones; occupancy radar reduces after-hours energy waste
Conference & Boardrooms	Radar-driven setback between meetings cuts energy consumption without sacrificing system readiness
Restaurant Dining Floors	EEV silencing preserves conversational ambiance; even coverage maintains guest comfort across varying party sizes
Hotel Lobbies & Event Spaces	Independent vane steering adapts airflow patterns to changing furniture layouts and event configurations
Premium Retail Showrooms	Consistent climate control across sales floor; setback mode activates during low-traffic periods
