“…However, one of the urgent problems in the development of underground construction is environmental safety. This requires the use of energy efficient lighting systems and mechanical ventilation [2]. It should also be noted that underground building structures are characterized by increased moisture content due to contact with wet soil, which causes problems during operation: infiltration of ground moisture, development of fungal infections, etc.…”

Preserving the ecological comfort of the urban environment forces architects to look for compromise solutions. One of them is the development of underground urbanism not only for transport infrastructures, but also for public buildings. In this case, environmental issues are relevant. The air quality in underground parking lots and in the adjacent area must comply with environmental standards. Underground parking lots are local sources of pollution. Therefore, during the construction of parking lots, design solutions should be carefully analyzed, especially ventilation issues. An effective method is mathematical modeling. The article considers the use of numerical simulation for the organization of ventilation using jet ventilation. The results of numerical simulation of a system of differential equations describing the processes of heat and mass transfer using a modern system of jet ventilation are presented. The use of jet fans makes it possible to ensure the permissible concentration of CO in the exhaust shafts. It is substantiated that the choice of locations for jet fans should be based on the analysis of velocity fields and concentrations of harmful substances. The article considers the features of jet ventilation in underground car parkings. The results of a numerical simulation of a system of differential equations describing heat and mass transfer processes using a modern jet ventilation system are presented using the example of an underground parking.

“…Increasing the number of jet fans does not improve mechanical ventilation system efficiency. Using LMA concept in the design shows the length of the time of the stagnation areas in different sections in an underground car park [12]. To improve air quality in underground car parks, various mechanical ventilation strategies have been developed.…”

The jet fan ventilation system is one of various ventilation systems available for the purpose of carbon monoxide extraction in underground car parks. Such a system is dependent not only on the rules applied during the design, but also the architecture of the underground car park. This paper describes a numerical model used to analyse air stagnation areas, airflow and streamline patterns and the influence of partition walls on the jet fan ventilation system. Additional focus is on the validity of the choice of the jet fan ventilation system for the underground car parks with partition walls. Results show that jet fan ventilation system is not suitable for all underground car park architecture layouts.
