Bio-coated surfaces with micro-roughness and micro-porosity: Next generation coatings for enhanced energy efficiency

Due to growing cooling demands as well emerging global warming and climate change issues, systems should be more efficiently utilized. Boiling is an effective heat transfer mechanism, which has a critical role in many systems. Surface modification considered the major approach for boiling enhancement. In this study, we developed microbial bio-coating surface technique phase applications. Thermoacidophilic Sulfolobus solfataricus coating was implemented using facile dip method on different metallic non-metallic surfaces. Controlled by drying conditions, exhibited rough porous morphologies. When tested setup, bio-coated surfaces offered enhancements up 76.3% Critical Heat Flux (CHF). Next, miniature evaporator coated real-world air-conditioning applications, coefficient of performance (COP) 11% clearly revealed potential energy saving purpose reduction greenhouse gasses. Furthermore, evaporators reduced exergy destruction rate 8%. This study not only offers new type morphology, but applicability proposed also proven air conditioning system.
