HVAC LAB | Spring Semester 2025

This portfolio demonstrates a holistic understanding of HVAC systems through measurements, experiments, theoretical concepts, and energy performance simulations. Key learnings include evaluating ventilation effectiveness, indoor air quality, psychrometrics, and the thermodynamics of air conditioning systems. It explores various HVAC system types, their components, and appropriate real-life applications based on loads and utility. Simulation studies focused on optimizing system selection, efficiency, and load matching. Comparative analysis of air-cooled vs. water-cooled chillers and energy recovery strategies highlights the importance of right-sizing, zoning, and effective control strategies to enhance system performance and occupant comfort across diverse climatic conditions.
