Thermal systems integration for fuel economy - Tiffe

Abstract

The TIFFE project is devoted to the development of an innovative integrated vehicle thermal system to improve the on board thermal management and the energy efficiency. The project main contents are a dual loop air conditioning where one loop transfers the cooling power and one loop rejects the heat, a two-levels temperature heat rejection system to dissipate the high temperature heat (e.g. engine waste heat) and to cool locally the vehicle auxiliary systems, a new generation of compact fluid-to-fluid heat exchangers and use of innovative coolants (e.g. nanofluids): to improve the heat rejection and redesign the heat exchangers. The approach benefits can be summarized in a cost reduction, due to resize and integration of the thermal systems, and fuel economy increase of 15% on real use. © 2010 Springer-Verlag Berlin Heidelberg.
