  • Page 11: Main Features

    • Introduction Main features Creating maximum comfort 6-1-1 Inverter technology The linear VRV system makes use of a variable Proportional Integral (PI) control system which uses refrigerant pressure sensors to give added control over inverter and ON/OFF control compressors in order to abbreviate control steps into smaller units to provide precise control in both small and larger areas.
  • Page 12 6-1-3 Less frequent start/stop cycle • The technique adopted by Daikin, of regulating the capacity using multiple compressors clearly results in minimum switching losses and power surges because of the overlap in capacity and frequency • Since Daikin utilises small 5HP inverter compressors, the influence of harmonics is less than that generated by a single large compressor •...
  • Page 13 • Introduction Main features Creating maximum comfort 6-1-4 PID control Proportional Integral Derivative control with an automatic capacity balancing circuit: – enables the use of lengthy piping up to 100 meters (actual length) – consists of two control systems: Oil control system that controls the refrigerant oil volume to prevent it from raising or backing up in the pipes Refrigerant flow stabilization mechanism: prevents refrigerant drift, caused by level difference of indoor units in the same system.
