Occupancy-Aware Four-Way Cassette with Acoustic-Grade EEV Silencing Radar-Driven Demand Control Noiseless Refrigerant Routing and Seven-Step Fan Matching

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

When an open-plan floor plate hosts fluctuating occupancy from dawn to dusk, a static-output cassette wastes energy on unoccupied zones and under-serves crowded areas. The Midea V8 Four-Way Cassette solves this with an integrated millimeter-wave radar module that continuously scans for human presence—ramping output when the room fills and retreating to setback mode when it empties. Paired with electronic expansion valve noise cancellation that eliminates refrigerant hiss at the panel, this unit redefines what specifiers should expect from a ceiling cassette in the commercial VRF class.

The four-sector discharge geometry ensures no corner escapes coverage, while per-vane independence lets designers tailor the throw pattern to non-standard room shapes. Seven discrete fan steps give facility engineers the granularity to match airflow precisely to real-time thermal gain—neither over-delivering nor under-performing. Add the V8 family's full digital drainage suite—monitored pump, anti-sweat logic, and water-level fail-safe—and the Four-Way Cassette emerges as the most intelligence-dense ceiling unit in the portfolio.

Core Highlights

01 — Omnidirectional Coverage from a Single Central Point Four discharge vectors radiate outward from the ceiling plane, filling every corner of square or near-square rooms with conditioned air from one mounting location—minimizing the unit count required on each floor plate.

02 — Millimeter-Wave Occupancy Radar The embedded mmWave sensor distinguishes occupied from unoccupied states with high confidence. Upon vacancy detection, the unit transitions to a reduced-output setback profile; re-entry triggers an immediate return to active comfort mode. This autonomous demand-response loop harvests energy savings in spaces with unpredictable schedules—conference rooms, training centers, multi-use halls.

03 — EEV Noise Elimination Algorithm A dedicated control routine drives the electronic expansion valve through a self-calibrating adjustment cycle that suppresses refrigerant flow noise at the ceiling panel. Occupants below experience a consistently quiet environment without the intermittent hissing that undermines acoustic comfort in conventional cassette designs.

04 — Dual-Point Temperature Sensing Thermistors at both the wired controller and the indoor-unit chassis jointly construct a blended temperature reading that accounts for stratification and localized heat sources. The system responds to a more representative room condition rather than a single-point snapshot.

05 — Per-Vane Independent Steering Each discharge louver is individually addressable, allowing the four air vectors to be customized independently—closing off airflow toward unoccupied edges, columns, or glazing while maintaining full output toward the core occupied zone.

06 — Seven-Step Fan Discretization Seven distinct speed levels provide fine-grained airflow matching to actual thermal load conditions. During partial-load periods, stepping down the fan reduces both acoustic output and motor energy draw—compounding annual savings across a large installed base.

07 — Soft-Discharge Mode & Drain Protection The draft-free discharge mode routes air along the ceiling for radiant-style comfort, while the optional silver-ion drain pan delivers continuous bacteriostatic protection—together creating an environment that feels as healthy as it sounds.
