    Global, regional, and national burden of household air pollution, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021 by Fiona B, Bennitt

    Published 2025
    “…FindingsIn 2021, 2·67 billion (95% uncertainty interval [UI] 2·63–2·71) people, 33·8% (95% UI 33·2–34·3) of the global population, were exposed to HAP from all sources at a mean concentration of 84·2 μg/m3. Although these figures show a notable reduction in the percentage of the global population exposed in 1990 (56·7%, 56·4–57·1), in absolute terms, there has been only a decline of 0·35 billion (10%) from the 3·02 billion people exposed to HAP in 1990. …”

    An experimental study on achieving even-frosting for an air source heat pump using a novel dual-fan outdoor coil by Bai, Xiaoxia

    Published 2022
    “…Besides, as tTIAO values were decreased from 15 mins to 10 mins for both fans, and to 6 mins for Fan A and 8 mins for Fan B, heating/frosting operation duration was increased by 8.9% and 19.4%, respectively, at a higher and , as compared to those using the traditional single-fan outdoor coil. …”
