Top Class Efficiency
Single Screw Compressor
Daikin single screw compressor with integrated inverter and Variable Volume Ratio Technology
The inverter integrated in the compressor is refrigerant cooled:
New Daikin High Efficiency Inverter fans
The new high efficiency fan developed by DAIKIN with optimized geometry ensures the best ratio between airflow and power input. The inverter control ensures the optimum airflow in every condition.
VVR (Variable Volume Ratio)
The operating conditions of a chiller are subjected to sensible changes due to the variation of ambient temperature and load request from the plant. Screw compressors increase the pressure of the refrigerant by forcing it into a progressive smaller volume, from the suction to the discharge port. Once that the geometry of the compressor is defined the volume ratio is also defined. Daikin compressors can modify their own geometry thanks to variable volume ratio (VVR). The volume ratio will change by moving the sliding valves. VVR changes the point at which the gas leaves the compressor, and therefore changes the pressures at discharge which will be optimal at any condition.
