This project studied Heating, Ventilation, and Air Conditioning (HVAC) systems for commercial buildings. I completed an energy model Raleigh County Sheriff’s Department in West Virginia. This building’s HVAC has been completed by the consulting engineering firm: Scheeser Buckley Mayfield. I intern at this company, so they allowed me to use their original design as a basis for comparison. Load calculations, utility costs, energy consumption, and carbon footprint were derived from this energy analysis. The energy model compared three systems: variable air volume (VAV) with electric reheat, variable air volume with hydronic reheat, and variable refrigerant volume (VRV). Based on the …

In keeping with Cal Poly's focus on physically applying the concepts learned in the classroom, our team of engineering students has compiled a laboratory experiment displaying the basic thermodynamic cycle found in air conditioning systems. This vapor compression cycle is displayed on a visualization board that features all four major components of the system: the compressor, the evaporator, the condenser, and the throttling valve. Students will take measurements of temperature and pressure at each stage in the cycle and also gauge the power draw from the compressor to gain an understanding of how performance and electricity cost come into play …
