Notes
- Minimum evaporator flow rate based on a water velocity of 0,5 m/s.
- Minimum condenser flow rate based on a water velocity of 0,3 m/s.
6.8 - Minimum temperature difference
The maximum flow rates recommended by Carrier limit unit operation with a ∆T (entering - leaving) of 3 K in the sections shown below:

To achieve a temperature difference of 3 K at the condenser, Carrier recommends the installation of option 102C.
To achieve a temperature difference of 3 K at the evaporator, Carrier recommends the installation of option 100C.
