Product Description
AirBoost Screw Chiller 316-1449 kW Free Cooling Carbon Intelligence T3
When Free Cooling Meets Variable-Speed Precision Every Operating Hour Becomes a Carbon Saving
Product Overview
The Midea AirBoost Air Cooled Screw Chiller eliminates traditional efficiency compromises, delivering 397-1,449 kW on R134a and 316-1,335 kW on R513A. This platform matches water-cooled part-load efficiency in many climates while consuming zero process water and generating fully auditable sustainability performance data.
The variable-frequency screw compressor with 0.1 Hz precision control achieves IPLV exceeding 5.0 per AHRI 551/591, representing 30-40% lower annual energy consumption versus fixed-speed alternatives. The triple free-cooling architecture exploits cold outdoor air to reduce or eliminate compressor runtime for 2,000-4,000 hours annually, delivering 35-50% energy savings during those periods.
Key Features
Triple Free Cooling Carbon-Reduction Strategy
Three free-cooling modes provide the most powerful carbon-reduction feature in the air-cooled screw chiller category:
- Direct free cooling: zero compressor energy when ambient conditions permit
- Indirect free cooling: plate heat exchanger isolation protects end-user equipment
- Mixed mode: partial compressor blended with free cooling during shoulder seasons
- 2,000-4,000 hours of compressor-free operation annually in climates below 15°C average
- Free-cooling hours are metered separately, providing auditable carbon-reduction data
- 35-50% energy savings during free-cooling periods reduce annual Scope 2 emissions
Variable-Frequency 0.1 Hz Precision Control
Demand-responsive cooling system that dynamically tracks building thermal load in real time:
- 0.1 Hz frequency resolution matches motor speed to load within fractions of a kilowatt
- IPLV exceeds 5.0 per AHRI 551/591 - 30-40% lower annual energy versus fixed-speed screw chillers
- VFD eliminates starting inrush current, reducing peak demand charges
- Enables participation in utility demand-response programs as a flexible load resource
R513A Low-GWP Refrigerant for Compliance
Strategic decision about long-term regulatory compliance and carbon reporting:
- R513A GWP of 573 versus R134a GWP of 1,430 - 60% reduction in direct carbon impact
- Compliant with EU F-Gas Phase-Down requirements for new installations
- Reduces Scope 1 refrigerant emissions exposure
- Mitigates financial risk of future carbon pricing on high-GWP gases
T3 Certified Climate Resilience
Climate-resilience planning embedded in equipment selection:
- T1/T3/FC AHRI certification validates performance across full -25°C to 52°C envelope
- Full capacity at 52°C ambient provides climate-resilience margin for future warming
- Validated operation at -25°C covers continental winter conditions
- Single specification across multiple climate zones simplifies procurement
60-Second Recovery for Continuous Operations
Business-continuity risk management for mission-critical applications:
- Full setpoint restoration within 60 seconds of power interruption
- Compared to 3-5 minute recovery of conventional fixed-speed screw chillers
- Reduces need for backup generator capacity and associated fossil-fuel consumption
- Protects product integrity in pharmaceutical and food-processing environments
8-Unit Parallel Plant with Sustainability Dashboard
Comprehensive sustainability performance record for entire chiller plant:
- Maximum 8 units in parallel for plant capacities reaching 11,600 kW on R134a
- 7-inch touchscreen controller with integrated BMS communication
- Real-time plant COP, cumulative energy savings, and free-cooling contribution displayed
- Data exportable for ESG, carbon disclosure, and certification reporting
