Abstract
This paper presents a methodology for assessing and monitoring the cleaning state of a heating, ventilation, and air conditioning (HVAC) system of a building. It consists of a noninvasive method for measuring the amount of dust in the whole ventilation system, that is, the set of filters and air ducts. Specifically, it defines the minimum amount of measurements, their time table, locations, and acquisition conditions. The proposed method promotes early intervention on the system and it guarantees high indoor air quality and proper HVAC working conditions. The effectiveness of the method is proved by some experimental results on different study cases.
Highlights
Particulate pollution has recently drawn the attention of public institutions, environmental associations, and researchers in different fields like medicine, engineering, and so on
Indoor air quality did not receive the same attention of outdoor air quality, especially for what concerns institutional rules and restrictions at both national and European level
Scientific studies have confirmed that 50% of energy consumption of a building is for HVAC system [7]
Summary
Particulate pollution has recently drawn the attention of public institutions, environmental associations, and researchers in different fields like medicine, engineering, and so on It consists of a mixture of organic and inorganic substances that are produced during natural or human processes. Indoor air pollution causes several health damages such as asthma, allergies, bronchitis, and general diseases, recently denoted by Sick Building Syndrome [5, 6]. Despite these clear evidences, indoor air quality did not receive the same attention of outdoor air quality, especially for what concerns institutional rules and restrictions at both national and European level. It is reasonable and desirable to have a tool for indoor air quality which automatically
