Background & Policy context
The project was devoted to the development of an innovative Integrated Vehicle Thermal System based on the integration of vehicle thermal systems to improve on-board thermal management and energy efficiency.
The objective of TIFFE was to create a cost reduction (due to resizing the systems and their integration) and a remarkable fuel economy increase.
The major project works concerned:
- Dual loop air conditioning: one loop to transfer the cooling power and one loop to reject the heat;
- Two-levels temperature heat rejection system: one temperature to reject the high temperature heat (e.g. engine waste heat) and one temperature to cool locally the vehicle auxiliary systems;
- Innovative heat exchangers: new generation of compact fluid-to fluid heat exchangers and application of innovative technologies for fluid-to-air heat rejection;
- Use of innovative coolants (e.g. Nanofluids). To improve the heat rejection and redesign the heat exchangers TIFFE benefits can be summarised in a Cost Reduction (due to resize of the systems and their integration) and Fuel Economy increase of 15% on real use thanks to the:
- improvement of the aerodynamics due the new front end design - increase of auxiliary systems efficiency thanks to the local cooling;
- engine overall efficiency thanks to a fine control of heat exchange, local cooling (turbocharge, fuel, etc) and improvement of the engine intake;
- the reduction of engine re-starts on Hybrid or Stop and Start vehicle due to cabin thermal comfort: the dual loop air conditioning with a designed thermal inertia guarantees thermal comfort when the thermal engine is off;
- compact Refrigeration Unit compliant with Low GWP refrigerants R744 or flammables (e.g. R152a, R1234yf). Two prototypes will be realised and validated:
- a gasoline passenger car with Stop and Start function;
- a diesel Light Commercial Vehicle with hybrid power train Both will undergo to a complete series of road and climatic chamber tests and a long range road test. For example from Catania (I) to Cape North (N) to verify the reliability and effectiveness of the system and to promote its exploitation.

The most relevant results can be summarised as follows:
- A second IVECO Daily TIFFE demonstrator has been realised (F1A engine) with improved components (liquid cooled condenser, liquid cooled charge air cooler and front thermal module) and fully validated. The results are very promising showing a fuel economy increase of up to 5%.
- A specific active shutters system has been designed and prototyped for the Low Combination Vehicle (LCV) application.
- The system control strategies have been defined and implemented on the LCV application.
- The system architecture has been refined for both the applications.
- The Compact Refrigeration Unit has been designed, prototyped and validated in laboratory. Two units will be then realised for the LCV and passenger car application.
- A passenger car TIFFE demonstrator (Ford Focus) has been realised to undergo experimental validation.
- The flat heat exchanger technology has been further developed and refined realising a new aerodynamic underbody and engine hood based on the roll bond heat exchanger technology while a different technology is under testing for mudguards.
