Analysis of Indoor Air Quality and PMV-PPD Model in Dynamic Conditioned Car Cabin

Car Cabin Air Quality Sensors and Systems

It is not surprising that air quality in vehicle cabins is usually found to be worse than that typically found in homes or workplaces, especially when so many exhaust pipes are only inches away from adjacent vehicles. Pollutants find their way into the cabin via the ventilation system, also known as the Heating, Ventilation and Air Conditioning (HVAC) system. Independent studies [1–3] have show...

Analysis of Indoor Air Quality and Development of New Air Cleaner for Railroad Passenger Cabin

Indoor air quality investigation at air-conditioned and non-air-conditioned markets in Hong Kong.

To characterize indoor air quality at the markets in Hong Kong, three non-air-conditioned and two air-conditioned markets were selected for this study. The indoor air pollutants measured included PM(10) (particulate matters with aerodynamic diameter less than 10 microm), total bacteria count (TBC), carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO(2)) and sulfur dioxide (SO(2)). The...

Car indoor air pollution - analysis of potential sources

The population of industrialized countries such as the United States or of countries from the European Union spends approximately more than one hour each day in vehicles. In this respect, numerous studies have so far addressed outdoor air pollution that arises from traffic. By contrast, only little is known about indoor air quality in vehicles and influences by non-vehicle sources.Therefore the...

Screening for Indoor Air Quality Express Assessment Protocol of Air-conditioned Offices

A successful Indoor Air Quality (IAQ) surveillance plan is essential for healthy and safe workplaces; yet it is costly to sample all air pollutants of the entire community. In Hong Kong, a voluntary IAQ certification scheme for workplaces proposes the acceptable concentration levels of nine common indoor air pollutants, namely carbon dioxide (CO2), carbon monoxide (CO), respirable suspended par...
