 | Daikin says its new generation of inverter driven screw compressor chillers with R1234ze(E) refrigerant will provide a long-term solution that supports the HFC phase down. |
The air-cooled TZ series will be available from 130 kW up to 830 kW cooling capacity. The water-cooled VZ series will be available from 340 kW up to 1600 kW cooling capacity. The range will be equipped with a Daikin-designed inverter driven single screw compressor with Variable Volume Ratio (VVR) technology.
An inverter drive modulates chiller capacity at part load in the most efficient way, while VVR (Variable Volume Ratio) adjusts compressor operation at any temperature conditions. A sliding valve fine-tunes refrigerant discharge pressure to match the operating condensing pressure. Dakin says the inverter drive for capacity control and VVR for discharge pressure fine-tuning, work together to optimise efficiency in any operating condition.
