Contribution to a life cycle exergy analysis of heat pumps with various evaporator sources.

Author(s) : CURTI V., FAVRAT D., SPAKOVSKY M. R. von

Summary

There is a growing need for the analysis of energy systems not only on the basis of their operation life, but also on the basis of considerations for the manufacturing and recycling phases. Environmental and to a lesser extent resource scarcity factors should also be taken into consideration. A general unified thermodynamic approach based on exergy is briefly summarized. The main idea of this approach is to minimize the cumulated exergy losses of operation, manufacture and recycling, distributing the exergy of manufacture (the so-called gray exergy) and recycling over the life time of the system. Additional levels of analysis consist of introducing pollution and resource scarcity factors. In the paper, the first level of analysis (exergy analysis with gray exergy) is applied to four domestic heat pumps operating with different evaporators.
