Design and Development of Duct System for Classroom Ventilation
Abstract: This paper presents the design, development, and performance evaluation of a duct-based ventilation system for efficient air circulation in enclosed spaces. The system delivers a steady airflow of 550 CFM using a circular inline fan integrated with galvanized sheet metal ducts to minimize pressure losses and ensure uniform distribution. Performance tests conducted under real environmental conditions measured ambient temperature, duct inlet and outlet temperature, and airflow rate. Results confirmed that …

HVAC Design by Using Green Building Norms
Abstract: An HVAC system can be describing as a system which removes the heat from a desired space by pumping the heat from one place to another which result a cooling effect, also by lowering the temperature. HVAC work for a good indoor air quality by using latest filtering technologies. The major components of the HVAC system are, Heat exchanger, Evaporator coil, Thermostat, Refrigerant lines, Condensing unit, drain piping system, electrical …

Study on Improvement of Air Quality in Underground Car Parking Area Using Jet Fan
Abstract: In recent years, jet fans have become a popular alternative to traditional ducted systems for ventilating pollutants in large parking areas like underground car parks and tunnels. Proper forced draft ventilation is necessary to remove harmful pollutants, such as vehicle exhaust fumes and smoke in the event of a fire. It is crucial to have a quantitative understanding of how exhaust gases, containing various toxic particles, propagate in these areas.So …

Enhancing Energy Efficiency in HVAC Systems: A Comprehensive Study of EC+ Fans, VFDs, and AI Integration
Abstract: This research paper explores the integration of EC+ fans with Variable Frequency Drives (VFDs) and Permanent Magnet (PM) motors to enhance energy efficiency and operational performance in heating, ventilation, and air conditioning (HVAC) systems. An extensive energy audit was conducted at the BidP plant in Bangalore, focusing on air handling units (AHUs) in Hangar 101. The audit revealed substantial variations in fan efficiency, secondary fan performance, power consumption, and airflow …
