This paper represents the complete design of an HVAC system for an American Restaurant in Madison Wisconsin, especially focusing on balancing comfort, capability and cost-efficiency. A number of crucial factors are taken into account in the system design, such as duct size, airflow rates, heating and cooling loads, and weather conditions. To attain balanced pressure drops and ideal airflow distribution, the paper used the equal friction method for duct sizing. Building Drawings were created using Revit 2021 Software. Which helped with the accurate planning of diffuser and air handling unit (AHU) locations. In order to ensure compliance with industry standards, thorough calculations for pressure drops, ventilation needs, and thermal loads were carried out. The resulting HVAC system design shows a viable and successful solution for medium-sized restaurant buildings by efficiently managing energy flows, enhancing indoor air quality, and creating a comfortable environment for occupants.
