| dc.description.abstracten | Thermal collectors are widely used to produce sanitary hot water and are expected to provide more and more thermal energy to the heating system of buildings in the near future. Their main component is a thermally conductive panel aimed at: (i) converting light into thermal energy and (ii) extracting thermal energy and transporting it to a heat storage unit, using a fluid and forced convection.
Few materials can fulfill both objectives. Generally, objective (ii) is met using a metallic substrate like copper while objective (i) is reached using a “selective coating”. Such a coating, and more generally surface treatments, may be energy-consuming. Besides, they are often associated with liquid pollutions, especially due to surface preparation. However, LCA data concerning surface treatments are still scarce and many of them left yet undocumented.
In this work, we present LCA for a coating dedicated to absorb light in a thermal collector. The coating process consists of a semi-continuous physical deposition. The study includes:
- The inventory of inputs and outputs of a coating chain, including surface preparation
(degreasing, etching) and estimates for the target consumption.
- An impact assessment, using Impact 2002+; one stresses the influence of the batch
size (i.e. amount of coated square meters), since launching a new production has a
significant impact.
Results are expressed per m2 of coated sheet and incorporated in a complete collector
study. The coating represents less than 2 % of hot water production impact, for all damage categories. The main contributions are the electricity consumption necessary for the vacuum and, to a lesser extent, the steel sheet used to “tune” the process. | en_US |
