CALCULATION OF THE VENTILATION SYSTEM FOR OFFICE BUILDINGS

Abstract

This thesis presents a study on the calculation of ventilation requirements for an office building. The aim of this research is to determine the optimal ventilation rate necessary to maintain indoor air quality and occupant comfort. Various factors such as occupancy levels, building size, and outdoor air quality are considered in the calculations. The study utilizes mathematical models and simulation tools to estimate the required ventilation rates for different scenarios. The results of this research will provide valuable insights for building designers and HVAC (heating, ventilation, and air conditioning) engineers to improve the overall indoor air quality and energy efficiency of office buildings.
Ventilation – the recirculation of fresh air around a closed space or the system air through the conducting passages between the atmosphere. It is a process of replacement of indoor air with fresh outdoor air. It is movement of indoor air to out and outdoor air to inside a closed area. There are two types of ventilation: Natural ventilation – pressure difference is caused by difference between densities of interior and exterior air given by the temperature difference wind velocity providing on windward facade positive pressure and on leeward negative pressure. Mechanical ventilation – pressure difference is caused by dynamic pressure of a fan and blower. It is systems circulate fresh air using ducts and fans, rather than relying on airflow through small holes or cracks in a home’s walls, roof, or windows.
