2.2 Material specification
2.3 Range of Application
2.3.1 Water inlet temperature
To prevent condensate from forming on non-insulated casing parts when the tempera-
ture falls below the dew point during cooling operation, certain minimum inlet tempera-
tures must be maintained. These temperatures depend on ambient temperature and
indoor relative humidity and are specified in the following diagram.
Example:
The room temperature is 28°C, the relative humidity is 60%. According to the diagram
(fig. 2-2), the minimum allowable water inlet temperature is 8°C.
