NOTE: 1. Full load ow minimum is the minimum allowable ow at full load conditions, and/or for a constant ow system.
2. Part Load ow minimum is the minimum allowable ow for a partially loaded unit, which is only applicable a variable ow system.
Flow may only be reduced proportionally to load, i.e. a ow reduction of 25% from the design ow rate is only allowable if the chiller
load is reduced by 25%.
