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.
Top class efficiency:
EER up to 3.6
ESEER up to 5.5
