About the project
TARIP will validate the technical feasibility of a robust and flexible industrial thermoacoustic heat pump (TAHP) technology capable of operating with supply temperatures between 150 to 250°C and temperature lifts of up to 100K. The heat pump will use a working fluid (Helium) that has zero GWP & ODP and is non-toxic and non-flammable. TARIP will develop and pilot a first-of-a-kind electrically driven TAHP at TRL5/TRL6 (200 kWth).
Ambition in TARIP is to scale up the bench scale industrial thermoacoustic heat pump to pilot scale, with enhanced power density and improved COP. The ambitions are summarized below :
• Prove double acting piston operation;
• Realization of 20-fold increase in power output to 200 kW pilot scale;
• Increase of the relative Carnot efficiency of the TAHP vessel to 60% by lowering internal heat losses, improved components (heat exchanger and regenerator) and by compressor optimization;
• Cost effectiveness is improved by standardized design and industrial production techniques for heat exchangers and the implementation of the double acting piston;
• Doubled power density by application of patented booster component.
The pilot TAHP will be designed using the thermoacoustic modelling software based on the existing bench scale unit and using as input data the compressor operation parameters like stroke, bore, and frequency and the process data form ArcelorMittal like the temperatures of the heat source and heat sink. The different components like heat exchangers, regenerator, and booster will be developed, designed, built, tested in separate setups, and validated against the expected performance. The pilot scale TAHP will be tested on 200kW in the TNO Carnot laboratory operating with supply temperatures between 150 to 250°C and temperature lifts of up to 100K.
