Centrifugal compressors

Where the volume flow of refrigerant required, for example, in large capacity water chillers, centrifugal compressors are commonly used. Where wide variations in load occur, the most common methods of control of power are the inlet valve regulation suction or discharge bypass. How to reduce efficiency.

These machines are usually specially selected and corresponds to the evaporators and capacitors manufacturer, then comes pre-mounted on a support (packaged chiller). The machines are usually specified conditions, necessary in a liquid (usually chilled water). If the reduction of the load for a long time expected, the manufacturer can take this into account when specifying the machine, and to mitigate the loss of effectiveness described above...
