6. Water temperatures/ air volumes
The conversion diagram shows heater capacities in KW under different conditions. These
conditions may be:
- Water temperature, for example 90/70°C (Regime)
- Air temperature sucked by the fan (Air temp)
- Turning speed of the fan. When the 5-step switch is applied, the power supplied (voltage) is
relevant.
In addition following information can be selected from the conversion diagram:
- Output (kW)
- Air volume (m3/h)
- Noise level (dB)
- Discharge temperature (°C)
- Water flow (m3/h)
- Water pressure loss/water-sided differential pressure (kPa)
6.1 Example
What is the output of a WWH 230 with a water supply (regime) of 80/60 °C, in a room with a
environment temperature of 10 °C? The 5-step switch is on stage 3.
Look in the WWH 230 diagram. Select on the vertical axis the field ‘regime 80/60 °C’ and then in
the column ‘air temperature’ 10°C.
The output is now shown on the horizontal axis
in the field speed 3, under the column kW
(answer= 21 Kw).
