The goal of setting up smoke evacuation systems for parking lots, evacuation and control of heat, smoke and fire products, as well as ventilation of toxic gases caused by car engines and vehicle exhaust under normal operating conditions. It is common. In this company, the European standard, BS 7346-7, and the operating criteria of the ventilation, evacuation and smoke control systems of the Tehran Fire Department are used for the design of the exhaust system of the parking lots. Based on this, in normal times for air ventilation, the system should be able to replace the air of all floors at least 6 times per hour. In emergency situations such as fire, this power should be at least equivalent to 10 times the air of the accident zone per hour. The capacity of compensating air is 50%-75% of the exhaust air depending on the project conditions.
The ventilation system of parking lots can be implemented independently in each floor and each zone or jointly for different floors.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\tIn this system, with the help of exhaust and fresh air fans, fresh air injection and polluted air evacuation are done. Also, in this method, for better performance, it is necessary that 50 percent of the valves are located at the lower level.
In this system, in addition to major problems such as: There is a decrease in the height of the roof due to the construction of ducts, the presence of non-ventilated points in the parking lots, high maintenance costs, noise generation, and a decrease in the beauty of the parking lots due to the high volume of the ducts.
Such as : Decreasing the height of the ceiling due to the implementation of ducting, the presence of unventilated points in the parking lots, high maintenance costs, creating noise and reducing the beauty of the parking lots due to the large volume of the canals.
Therefore, as a general rule, the use of channeling system in large parking lots not only has high costs, the efficiency and effectiveness of the system also decreases.\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tIn the parking lot air evacuation system using jet fans, horizontal channels are completely removed and jet fans are replaced. With their coordinated operation, jet fans can create air flow in the parking space, and our task of air transfer between two points becomes empty and fresh air. In this system, in addition to smoke control, the speed of smoke discharge is also increased compared to the duct system. In addition to the fact that this system has better performance in large parking lots, this system does not have the disadvantages of the drainage system.\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\tIn the design of parking lot ventilation systems, it is possible to check the accuracy of the design and the correctness of the proposed system's performance using air flow simulation (CFD) and fire in the parking lot. Due to the complexity of pollutant behavior, parking lot geometry and the number of air inlets and outlets, the analysis of parking systems is done accurately and with comprehensive modeling by the expert experts of Bostanchi Industrial Group using specialized software such as Pyrosim and Solidwork Flow Simulation.
With the help of these software, various simulations and analyzes can be done, such as:\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
