Energetic and environmental optimisation of drying process by integration of heat pumps (HP4Drying)
The main target of this project is to integrate HPs into different industrial drying processes in order to exploit the corresponding advantages by energetic and environmental optimization. The focus is on convective dryers because they are used most frequently and can be most conveniently modified to integrate HPs. By adapting HPs to operate under varying temperature levels (by using fluid mixtures, hybrid and multi-stage HPs, HPs with variable pressure ratio etc.) and developing innovative control systems, HPs could better follow the drying process. Thus the average efficiency of the HPs would increase substantially.
