AI Technical Summary
Existing refrigeration and freezing appliances with activated carbon filters require separate installation space and are inefficient due to energy loss from pressure drops caused by conventional filters.
Integrate activated carbon or antimicrobial materials into existing components like fans, air ducts, and containers to provide additional odor absorption and antimicrobial properties without reducing air volume flow.
Achieves effective odor reduction and antimicrobial functionality while maintaining optimal air flow efficiency by utilizing existing components as dual-function surfaces.
