6.3 - Minimum chilled water flow
The minimum chilled water flow is shown in the table in
chapter 6.7 “Evaporator and condenser water flow rates”.
If the system flow is less than the minimum unit flow rate,
the evaporator flow can be recirculated, as shown in the
diagram.

6.4 - Maximum chilled water flow
The maximum chilled water flow is limited by the permitted
pressure drop in the evaporator. It is provided in the table in
chapter 6.7 “Evaporator and condenser water flow rates”.
•
Select the option with one water pass less that will
allow a higher maximum water flow rate (see option
100C in the table in chapter 6.6 “Number of passes”.
•
Bypass the evaporator as shown in the diagram to
obtain a lower evaporator flow rate.

6.5 - Condenser water flow rate
The minimum and maximum condenser water flow rates
are shown in the table in chapter 6.7 “Evaporator and
condenser water flow rates”.
If the system flow is higher than the maximum unit flow
rate, select the option with one pass less that will allow a
higher maximum water flow rate. Please refer to option
102C in the table in chapter 6.6 “Number of passes”.
