Theoretical analysis of solutions on ventilation and smoke removal in indoor parkings

One of the most pressing problems of megacities is that the rate of increasing of the number of cars is bigger than the rate of providing parkings for them. At present, indoor car parkings are becoming an integral part of the infrastructure of big cities in Russia. This prompts the search for new solutions with investment potential and aimed at improving the efficiency of functioning of car parks. When designing a ventilation of underground parking lots, the main tasks are the following: ensuring that regulatory parameters of the indoors air are observed; ensuring fire safety, explosion safety; carrying out activities aimed at protecting the environment. Currently, the issues of improving ventilation systems remain topical when designing these improvements as to the characteristics of the systems that ensure efficient operation, making safety requirements more strict, and finding solutions that are more cost-effective. The article presents the results of calculations and comparison of characteristics, two technical solutions ensuring efficient operation of ventilation systems and smoke removal in indoor car parks. A model of indoor air flow was developed using the SOLIDWORKS software.
