P09 Development of surface coatings on heat exchangers
for reduced ice accretion and fouling

Research residence SP

The accretion of ice and dirt on heat exchanger surfaces has a negative impact on the performance and energy efficiency of heat pumps. Surfaces that would reject or delay the accretion of ice and dirt are expected to result in energy savings of 10-15%.The purpose of the project is to evaluate different types of surface coatings on heat exchangers, with the aim of reducing or delaying the accretion of ice and dirt. The ultimate aim is to improve the efficiency of heat pumps. The project group consists of industry- and research partners with high competence in the area of heat exchangers and heat pumps (Nibe, Danfoss, SP), materials (Gränges, SP), and surface modifications (SP, Beneq).
