A comparative analysis of two thermoeconomic diagnosis methodologies in a building heating and DHW facility

The way to deal with dynamic circumstances is thoroughly explored in this article. Likewise, this paper's main goal is to demonstrate an application of two thermoeconomic diagnosis methodologies in the building sector, one based on the malfunction and dysfunction analysis and the other one based on the characteristic curves of the components. The results obtained allow us to point out the advantages and limitations of both methodologies as well as to combine them and then develop a more reliable diagnosis.
