HP4D – Heat Pumps for Drying

This project aims to build international knowledge on resource-efficient drying with heat-pumping technology.

The proposed project will be used as a Swedish national project to contribute to the overall aim of the new IEA HPT Annex 59 in the form of a joint project with RISE, Chalmers and KTH as the executive team.

The project will collect Swedish case studies focused on industrial drying, mainly in forests, pulp/paper, agriculture/food.

Both state of the art and innovative solutions will be investigated and described, including needs surveys, analyses, and in-depth case studies will be analysed from a technical, practical and financial perspective to achieve a shift towards electrified resource-efficient drying. The successful implementation of these drying processes will address complex multidimensional challenges.

This proposed project will explore opportunities to significantly increase the efficiency, flexibility and cost-effectiveness of drying applications using heat pumps.
