A003 Thermal CO2 carpark

Field study on the indoor thermal environment and carbon monoxide levels in a large underground car park

Brief:

Indoor environment quality in a large underground car park in Hong Kong are studied: field measurements were divided into three parts: (1) assessment of the thermal environment; (2) measurement of the carbon monoxide concentration; and (3) a survey on thermal comfort. The indoor air temperature, relative humidity, instantaneous airspeeds, turbulence intensity, and carbon monoxide concentration at different locations in the car park were measured. Design and operation of the installed ventilation systems were studied and the number of cars staying at the car park was investigated. Correlations between the mean carbon monoxide and the mean air speed, the turbulence intensity, and the number of cars entering or leaving the car park were investigated.
