Industrial Heat Recovery and Heat Pumps Systems
Résumé
The growing costs of fuels and supply security concerns make it necessary to reduce energy consumption in industrial processes. The use of heat recovery technologies like Heat Pumps (HPs) is an effective way of achieving an energy saving and a significantly reduction in CO2 emissions. Around one third of the final energy used for thermal purposes1 is subsequently wasted through losses. The lowest temperature range of this heat could be technically recovered through HPs systems from energy end-uses like dryers, refrigeration systems, air compressors etc. HPs have made great technological progresses by providing at the same time useful heat at higher temperatures and the possibility of replacing boilers which consumed traditional fossil combustible to provide heat. The purpose of our work is a prospective energy analysis up to 2020, to highlight the availability and opportunities of existing and innovative high temperature heat pumps systems in French Food & Drink (F&D) industry. For that purpose, we implement a sectoral energy system optimization model using the ETSAP TIMES2 framework. It is a "Bottom up" technical economic model which provides a technology rich basis for estimating energy dynamics over a medium or long-term and a multiperiod time horizon.
