The Heating Power Demand

111 the stationary state the hear demand b for an industrial building is 

If the volume flow practically the same at every outdoor tempera- 

Plotting the heat demand against T should produce a straight line with a negative slope coefficient. 

If we look at a measured heat demand (Fig, 8.50) for an industrial budding, we sec that this is essentially the case. Deviations from the straight line are due to the following three factors
