with PICV control<\/p>\n

Function<\/p>\n

The fixed speed chillers are connected to the controller which opens and closes the flow through each chiller by turning the PICV on and off.<\/p>\n

The controller measures the inlet and outlet temperature to maximize Delta T and regulates the variable speed pump to maintain the required pump pressure.<\/p>\n

For optimal chiller efficiency, the use of cascade control is recommended.<\/p>\n

Benefits<\/p>\n

\n
• \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0The PICV ensures balancing of the flow and eliminates the use of both static balancing valves and differential pressure control valves.<\/li>\n
• \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Simple installation as only the PICV is required with no need for additional pressure or flow balancing valves.<\/li>\n
• \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Low total pressure loss in the system due to simple design.<\/li>\n
• \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0The flow can be set directly on the PICV without the need of a manometer or a commissioning unit.<\/li>\n
• \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0The differential pressure only needs to be checked at the PICV to set the required flow.<\/li>\n<\/ul>\n

  Considerations<\/p>\n

  \n
  • \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0A metering station can be placed on the main line if additional flow verification is required by the witnessing authority.<\/li>\n
  • \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0A minimum bypass flow controlled by a dynamic flow limiter is required by the chiller to avoid freezing as they are running at full capacity when switched on.<\/li>\n<\/ul>\n
