Investigation of Air Quality and Suspended Particulate Matter Inside and Outside of University Research Laboratories

摘要

Counting the aerosol particles and identifying the air quality are reflectors for the efficiency of heating, ventilating and air-conditioning system (HVAC). HVAC is an important system especially in construction, agriculture, food processing and animal farming sectors. The objective of the presented research was to study the changes in local conditions and air quality in research laboratories of Universiti Teknologi PETRONAS (UTP) due to research activities and construction going on in the university suburbs. To achieve our objectives, we have measured the aerosol particles by using DUSTTRAK~(?) in an indoor (with and without stimulus) and outdoor environment. We even further investigated the air quality of indoor and outdoor environment, through measuring carbon dioxide concentration, ventilation rate, light intensity, relative humidity and temperature by using Telaire 7001. Data was collected from both devices, analyzed and discussed thoroughly in the discussion section.
