Ecological Efficiency of the Energy System of Recuperators in the South of Siberia

The article studies the environmental efficiency of using a resource-saving energy system—supply and exhaust ventilation (recuperators) in the south of Siberia. The numerical results of calculations of the environmental efficiency of the recuperator as an autonomous system are given: annual savings of conventional and real fuel, maximum values of the volume of dry combustion products, CO2, SO2, NO2 and ash not emitted during the heating season when using this resource-saving technology. Carbon footprint reduction calculated. The calculation was made for coals used in the south of Siberia: Kuznetsk flame coal, Kuznetsk flame coal, Kuznetsk unbaked coal, Kuznetsk fat coal; Ekibastuz bakeless coal, Belovsky anthracite, Listvyansky anthracite and gases: Neryungrinsky, Tyumensky, Urengoysky, Yamburgsky. The calculation was made for the average area of a private house put into operation in the south of Siberia in 2021.
