Abstract
The appropriate ventilation for factory spaces with regard to volume flow rate and air velocity inside the factory is one of the most important factors in the improvement of the thermal comfort of workers and in the reduction of the percentage of pollution they are exposed to, which in turn helps to improve the work environment and increase productivity. It also could improve the performance of machines. Hence, overheating can cause various problems and malfunctions. In this study, three types of mechanical ventilation systems are compared: the wall fan extract ventilation system, the roof fan extract ventilation system, and the spot cooling system. The Ansys software has been used to conduct the computational fluid dynamics (CFD) simulations for the different cases and the ventilation effectiveness factor (VEF) has been used to compare the performances of the three systems. The ventilation factor notably relies on the temperature distribution produced through the modeling and the results show that the most optimal system that can be used for similar factory spaces is the forced ventilation system. Finally, it is also the best in terms of energy consumption, despite the increase in the initial cost of its installation.
Highlights
There is great emphasis on reducing the pollution resulting from industrial activities and rationalizing energy consumption within the industrial environment, and these issues are the most important elements when it comes to creating a sustainable design for industrial buildings [4]
The feasibility of the study of industrial building ventilation systems is a crucial step for ensuring the use of the most effective system in terms of providing a suitable work environment and reducing energy consumption
Traditional ventilation systems are the most commonly used in Egyptian industrial buildings due to their low initial costs and ease of installation
Summary
The Egyptian state’s plan for urban development is mainly accompanied by industrial development, which helps to expand development axes and attract inhabitants to new cities [1]. One of the most critical problems facing urban and industrial expansion is the variety in the climate between different areas, which is hoped to be expanded in the southern areas characterized by high temperatures [2,3]. There is great emphasis on reducing the pollution resulting from industrial activities and rationalizing energy consumption within the industrial environment, and these issues are the most important elements when it comes to creating a sustainable design for industrial buildings [4]. With the above in mind, it becomes clear that studying industrial buildings and finding appropriate solutions that create a comfortable work environment, as well as reduce energy consumption, helps to attract industrial investments
