In February 2023, Daikin enhanced its scroll compressor chiller range with R-32 by introducing a new air-cooled chiller series, increasing the maximum cooling capacity to 1,010 kW (up from the previous 704 kW). This aligns with Daikin’s commitment to delivering low-carbon solutions for both process and comfort cooling applications. The compact design of these chillers offers a footprint up to 3 metres shorter than equivalent screw chillers, making them a space-efficient solution.
In April 2024, Daikin further extended the range with new models offering cooling capacities from 180 to 400 kW and introduced the Shell & Tube evaporator option for units above 700 kW. These updates expand the scope of applications and improve system versatility.
Key Features of the Second-Generation Cooling-Only Chiller Range
The second generation of R-32 air-cooled chillers incorporates several innovative upgrades to optimise performance, efficiency, and operational flexibility.
- High Performance and Efficiency
- Daikin R-32 Scroll Compressors: Enhanced for exceptional full and part load efficiency.
- Redesigned Fans: Increased airflow, reduced noise, and improved overall performance.
- Metal Compressor Housing: Improves aesthetics and noise reduction.
- Wide Temperature Range: Operates in ambient temperatures from -30°C to +55°C, suitable for global projects.
- Advanced Features
- Rapid Restart: Keeps the unit controller operational for 180 seconds during power failures, enabling the compressor to restart within 30 seconds after power restoration and restoring full capacity in less than 3 minutes.
- Integrated Sequencing and Performance Monitoring: Previously available only on screw compressor units, now standard in this range.
- Mobile App Integration: Simplifies system monitoring and management, providing real-time data access.
- Flexibility for Critical Applications
The chillers are available in two efficiency versions and two sound configurations, catering to comfort and mission-critical applications like data centres. Integrated hydronic-free cooling is also offered for enhanced efficiency in key applications.
Compactness and Operational Flexibility
Daikin’s innovative design focuses on compactness and flexibility:
- Optimised Footprint: Redesigned condensing sections minimise unit dimensions, ensuring better utilisation of space.
- Free Cooling Capability: With capacities ranging from 150 to 1,344 kW, including glycol-free options, the chillers support significant pumping system savings.
- High Leaving Water Temperature: Capable of delivering evaporator leaving water temperatures of up to +30°C, improving efficiency and enabling extended free cooling mode operation in regions with mild climates.
New Additions: Extended Capacity Range and Shell & Tube Evaporator
- Lower Capacity Models (180–400 kW)
- Dual-circuit models deliver high part-load performance.
- SEER values comparable to screw technology with variable frequency drives, thanks to Daikin EC fans.
- Shell & Tube Evaporator Option (Above 700 kW)
The Shell & Tube evaporator is now available for larger models, meeting specifications for:
- Critical Cooling Applications: Ideal for industrial process cooling where reliability is paramount.
- Large Projects: Many specifications favour Shell & Tube options for durability and performance.
