Daikin introduces the new EWYS-4Z polyvalent unit, featuring Daikin's inverter-driven, single-screw compressors, designed to efficiently provide simultaneous cooling and heating for commercial and industrial applications. Utilizing R-513A refrigerant, which has a 55% lower Global Warming Potential (GWP) compared to R-134a, the unit maintains the same safety classification (A1).
Key Features and Performance:
- Capacity Range: 400 to 800 kW in both cooling and heating modes.
- Total Energy Efficiency Ratio (TER): Up to 7.89.
- Operating Temperatures: From -18°C to +50°C.
- Chilled Water Temperature Range: From -8°C to +20°C.
- Heating Water Temperature Range: From +30°C to +60°C.
Versatile and Reliable:
The EWYS-4Z is ideal for various applications, including industrial and commercial buildings, hotels, and hospitals, ensuring reliable operation and optimal performance in diverse locations and weather conditions. A reduced noise configuration is available, featuring sound attenuation through lower fan speeds and a specially designed compressor cabinet.
Simultaneous Heating and Cooling:
Equipped with two Shell & Tube heat exchangers, the EWYS-4Z can simultaneously meet cooling and heating requirements year-round, adapting to changing climatic conditions without needing seasonal changeovers. The system controls the refrigerant circuits independently, based on actual demand.
Efficiency and Sustainability:
- VFD Regulation and VVR Control: Ensures efficient operation with minimized energy losses.
- No Starting Current Spikes: Ensures smooth operation without current spikes.
- High Power Factor: Maintains a power factor greater than 0.95, reducing electrical losses.
- Quick Comfort Conditions: Rapidly reaches set-point conditions, switching modes in less than a minute.
Reliable Operation:
- Independent Refrigerant Circuits: Ensures maximum safety and ease of maintenance.
- Refrigerant-Cooled VFD Technology: Not affected by environmental conditions, ensuring unparalleled reliability.
- Balanced Mechanical Loads: Reduces component stress and extends the unit's life.
Integration and Monitoring:
- Daikin Intelligent Chiller Manager (iCM): Manages up to 8 units, optimizing capacity and minimizing energy consumption.
- Daikin on Site: A cloud-based remote monitoring system providing real-time data, ensuring proper functionality and preventive maintenance.
The new EWYS-4Z polyvalent unit sets a high benchmark in HVAC technology, offering significant benefits for commercial and industrial applications with its efficient, reliable, and sustainable performance.
