Minimal mass flow To maintain the output shown in the table, a turbulent flow must be ensured within the pipes in the panels. This minimum mass flow depends on the lowest system temperature. When heating, this corresponds to the return temperature. When cooling or in a combined cooling/heating mode, this corresponds to the cold water flow temperature. If the minimum mass flow per pipe is not achieved, this can result in a drop in performance of about 15 %. 100 Minimum mass flow in the pipe in kg/h 80 60 40 20 0 10 20 30 40 50 60 70 80 Lowest system temperature in °C Limit temperatures Cooling. The flow temperature of cooling ceilings should be chosen so that it only falls below the dew point and hence causes condensation on the ceiling in exceptional situations (for a few hours a year). For this, a dew point monitor must be installed on each cooling ceiling. This prevents condensation by using control technology to raise the flow temperature or interrupt the supply of cold air. A minimum flow temperature of approx. 16 °C is recommended for Central Europe. Heating. For normal room heights (up to approx. 3 m) and with a high level of ceiling coverage (approx. 80 %), the flow temperature should not exceed 35 °C. This will avoid an unpleasant indoor climate. 23 Dew point temperature of outside air in °C 22 21 20 19 18 17 16 Berlin Central European cities 15 0 1 2 3 4 5 6 7 8 9 10 Lower deviation of the dew point temperature 34
