Atmosphera water connections
The water circuit in the Atmosphera units is guaranteed for an operating pressure of 1000 kPa, although the Atmosphera units components are individually
designed and tested for a pressure of 1600 kPa.
For applications requiring an operating pressure of more than 1000 kPa, please contact your local Carrier representative.
Legend:
* Based on an entering water temperature of 7°C, entering air at 27°C dry bulb and 47% relative humidity, and a water temperature difference of 5 K at maximum
air flow (Eurovent conditions).
** Based on an entering water temperature of 50°C, entering air at 20°C and a water temperature difference of 10 K at maximum air flow (Eurovent conditions).
*** Refer to electrical data tables.
