    1. Introduction The PlantVisorPRO Floating Suction Pressure Control plug-in has been designed to reduce the energy consumption of showcases. To do this, it periodically analyses the operation of the showcases associated with the compressor racks that have been enabled, and, based on the duty cycle values calculated for each showcase, automatically modify the set point of the rack.

    Floating Suction Pressure Control 5. Opening Floating Suction Pressure Control To access the plug-in click and select PLUG-IN: the list of plug-ins installed will be shown: 6. Configuring Floating Suction Pressure Control After having entered the PLUG-IN section, double click Floating Suction Pressure Control: the main page is shown for configuring the control: Code +030220508 - rel.
  • Page 8 Floating Suction Pressure Control Click Configuration: the Systems page is shown, with the list of compressor rack controllers compatible with Floating Suction Pressure Control. On this page, select the systems to be enabled in the plugin. NOTE: any devices not compatible with Floating Suction Pressure Control are not shown in the list. NOTE: a maximum of eight systems can be enabled.

    Floating Suction Pressure Control 8. Checking the status of the systems After having started the control, the trend of the set point on each compressor rack can be checked by reading the graph on the main page. If all the showcases associated with the compressor rack have a duty cycle lower than the maximum set point defined for the showcase, Floating Suction Pressure Control will increase the value of the set point on the compressor rack.

    Floating Suction Pressure Control 9. Customising the compressor rack and showcase parameters Floating Suction Pressure Control is supplied with standard parameters that manage the operation of the control. Nonetheless, some of the compressor rack parameters or the maximum duty cycle of a showcase can be changed, for example to adjust the algorithm to the specific installation.
