The HVAC lab was an exploration into the world of heating, ventilation, and air conditioning beginning with a strong foundation in both theory and hands-on experimentation. The first half of the semester focused on understanding core concepts like the refrigeration and PH cycles, fan systems, air leakage through blower door tests, and the effect of indoor air quality through particulate matter measurements. This learning culminated in the installation and testing of Heat Recovery and Energy Recovery Ventilators (HRV/ERV), following proper protocols to evaluate their real-world effectiveness. The second half transitioned into the digital realm, where the performance of various HVAC systems were simulated—Packaged DX, air- and water-cooled VAV, and VRF in a G+2 office building located in a chosen city and climate. Through these simulations, we assessed each system’s energy use, efficiency, thermal comfort, and unmet hours, gaining a deeper understanding of how HVAC design influences building performance across different conditions.
