Four-Way Cassette VRF CE Certified High Airflow Hospital School Data Center HVAC Occupancy-Aware Four-Way Cassette with Acoustic-Grade EEV Silencing

Four-Way Cassette VRF System

CE Certified High Airflow HVAC Solution for Hospitals, Schools, and Data Centers with Occupancy-Aware Technology and Acoustic-Grade EEV Silencing

Advanced Demand Control & Noise Reduction

Radar-driven demand control, noiseless refrigerant routing, and seven-step fan matching for modern open floor plans. The Midea V8 Four-Way Cassette features integrated millimeter-wave radar that continuously scans for human presence, optimizing output based on occupancy while eliminating refrigerant hiss through electronic expansion valve noise cancellation.

The four-sector discharge geometry ensures comprehensive coverage, while independent vane control allows customization for non-standard room shapes. Seven discrete fan steps provide precise airflow matching to real-time thermal conditions, complemented by a full digital drainage suite with monitored pump, anti-sweat logic, and water-level fail-safe protection.

Core Features & Benefits

01 — Omnidirectional Coverage

Four discharge vectors radiate from a central ceiling point, providing complete room coverage from a single mounting location and minimizing required unit counts.

02 — Millimeter-Wave Occupancy Radar

Embedded mmWave sensor detects occupancy states with high confidence, automatically transitioning between active comfort and energy-saving setback modes.

03 — EEV Noise Elimination

Self-calibrating control routine suppresses refrigerant flow noise, ensuring consistently quiet operation without intermittent hissing.

04 — Dual-Point Temperature Sensing

Thermistors at both controller and unit chassis create blended temperature readings that account for stratification and localized heat sources.

05 — Per-Vane Independent Steering

Each discharge louver is individually addressable, allowing customized airflow patterns and directional control.

06 — Seven-Step Fan Discretization

Seven distinct speed levels provide fine-grained airflow matching to actual thermal load conditions, reducing both acoustic output and energy consumption.

07 — Soft-Discharge & Anti-Bacterial Protection

Draft-free discharge mode routes air along the ceiling for radiant comfort, while optional silver-ion drain pan provides continuous anti-bacterial protection.

Application Scenarios
