9.6 Connecting thermal fluids: additional batteries
If your equipment has additional water batteries, the water supply must be connected
according to applicable regulations and good practice by connecting the inputs and
outputs according to the corresponding battery labels:
Figure 10: Pre-cooling battery connections.
Water battery features:
-
Standard supply includes air/water heat exchangers with copper tubes and
aluminium fins.
-
The nominal values for cooling batteries are calculated with a standard
temperature jump in water of 5°C, entering at 7°C and exiting at 12°C.
-
For heating batteries, the nominal values are calculated with a standard
temperature drop in water of 20°C, entering at 70°C and exiting at 50°C.
- For calculating non-standard performance, please contact your FISAIR dealer.
NB. Ensure that the air to be treated does not contain aggressive components that may
react with copper or aluminium.
