FILTERING BUILDING BLOCK FOR AIR CLEANING

摘要

FIELD: air conditioning, particularly laminated building blocks used for building wall erection and having properties facilitating dust removal from ambient air passing into building. ^ SUBSTANCE: filtering building block for load-bearing wall enclosure erection comprises outer concrete layers formed of material mainly based on rigid cement mixes and porous layer arranged in-between. Porous layer is located in sealed cavity defined by outer concrete layer. Inlet and outlet orifices are made in opposite cavity sides. The inlet and outlet orifices are communicated with two chambers located near porous layer. The first chamber is provided with one-way valve assembly so that if ambient air pressure increases the valves are brought into opened state. The second chamber has one-way valve assembly and opens the valves if ambient air pressure decreases. ^ EFFECT: improved heat-insulation and sound-proofing properties of filtering building block used in load-bearing building structure. ^ 2 cl, 2 dwg
