Similarly, Figure 3.10 and Figure 3.11 show the modelled cooling and hot wateroutlet temperature profiles superimposed on the measured data for the samesimulation period used in the case of the chilled water dataset.Fig. 3.10 - Measured vs. modelled cooling water datasetsFig. 3.11 - Measured vs. modelled hot water datasetsBoth figures show good agreement between the measured and modelled datasets,although showing a slightly positive temperature bias when compared to the resultsobtained from the chilled water. In terms of the cooling water circuit temperatures,the maximum and mean error values between the modelled and measured datasetswere calculated to be 2.19°C and 0.22°C respectively. The calculated standarddeviation was 0.61°C. The hot water circuit temperatures showed a similar behaviourto the cooling water temperatures with the maximum and mean error values betweenthe modelled and measured datasets being 2.81°C and 0.46°C respectively, whilst the127
