Heating, Ventilation, and Air-Conditioning (HVAC) System in Physics Laboratory at Laguna University

This study designed and evaluated a HVAC system for the Physics Laboratory at Laguna University to improve thermal comfort and indoor air quality. Ducted and Blow-through systems were analyzed using cooling load calculations and CFD simulation through ANSYS Fluent. Results showed that both systems maintained acceptable indoor conditions; however, the blow-through system provided more uniform airflow and achieved a stable indoor temperature of in accordance to the recommended comfort range for laboratories. The selected system was implemented and tested under varying occupancy conditions, showing effective temperature regulation and positive user satisfaction. The study concludes that the blow-through HVAC system is the most suitable configuration for the Physics Laboratory.
