flow rate is required, an accurate flow meter must be
installed in the system.
Chilled Water System Volume
Minimum system volume requirements are indicated in
Figure 4, p. 25. Special applications may deviate from these
numbers as directed by Trane engineering. Operation below
these volumes will cause unacceptable system control
problems and the potential for evaporator failure.
