| Sumario: | [EN] This work develops a software to control and diagnose building thermal facilities based on thermoe-conomics. It is tested with the data obtained from three building blocks in the Basque Country (northern Spain) with the aim of detecting the potential energy saving points and mitigating environmental im-pacts. Some obstacles, solved, are related to the insufficient number of probes and the inherent errors of sensors. Besides, new methodologies for performing a thermoeconomic dynamic analysis are described. Apart from this, the inefficiencies of components are quantified, a dynamic cost calculation of all fiows is done and different operation modes are discussed. The outcomes of operation modes are discussed and their exergetic, economic and environmental average unit cost are calculated. In such way, the inter-vention of the control system is analysed and the operation modes with lower and higher fuel con-sumption are detected. The results show that domestic hot water (DHW) production has an average value of 13.72 c euro /kWh and heating of 12.92 c euro /kWh; in addition, boilers have 1,587 MWh of real losses. Besides, the operating modes dynamic analysis opens a new research line for thermoeconomics appli-cations. This information is a key fact for control optimization searching the high performance of buildings. |
