Staging control for constant speed pumps
This model describes a simple staging control for two
constant-speed pumps in a chilled water plant with two chillers and
a waterside economizer (WSE). The staging sequence is shown as
below.
- When WSE is enabled, all the constant speed pumps are commanded
on.
- When fully mechanical cooling (FMC) mode is enabled, the number
of running constant speed pumps equals to the number of running
chillers.
