The calculation methods given in this section are not intended in the modelling but as a means to give insight about the network measures. Linear heat density: The ‘Linear Heat Density’ is a measure in DH systems showing the denseness of the overall heat load/supply as per the wideness of...
Then, the calculation formula of mutual information can be written as (17) Here, hf = ∑rhfr, hr = ∑fhfr, and N = ∑f,rhfr. Then, the gradient of the mutual information MI relative to the parameter Φ based on the B-spline FFD model is (18) According to the principle of ...

For this design, the height of the tank (l) was adjusted to 450 mm after this calculation process to stop overfilling. For testing, this height line should be used as a marker to know how much water is required for successful testing. The amount of water required (Vwater = Vtank - ...
Therefore, the number of solar collectors is determined as the nearest integer resulting from the calculation: 𝑁=𝐴𝑐,𝑇/𝐴𝑐.N=Ac,T/Ac. (10) The required volume of the storage tank is directly related to the solar collection area through the specific storage volume, namely, ...
The room model, as part of the Modelica Buildings library, covers all physical effects relevant for calculation of a room’s thermal dynamics. It also allows optimization of the heat supply controls with arbitrarily sized time steps. However, more complex physics causes the larger size of the ...
