Ventilation for underground carparks is critical to indoor air quality (IAQ) due to carbon monoxide (CO) emissions from cars. The IAQ within a multi-level underground carpark of a shopping mall has been investigated using computational fluid dynamics (CFD) model based on ANSYS-FLUENT (18. 1) software. https://herbsdailyes.shop/product-category/cardio-pulmonary-monitors-ecg-mounts/
