Bio

I work in the Building Equipment Research Group on new and improved types of energy-efficient building equipment, with specific applications in HVAC, water heating and appliances. The research involves thermodynamic system modeling, component modeling, engineering analysis, design optimization, prototype fabrication, and performance evaluation via experimentation. Past and ongoing work includes:
- Novel rotating heat exchanger for refrigeration applications: Conducting detailed performance characterization experiments on vapor-compression system with micro-channel baseplate evaporator/rotating fin combination; study of frost formation and removal from heat exchanger fins using high-speed imaging.
- Ultrasonic clothes dryer: Conducting experiments in mechanical extraction of water from clothing using piezoelectric transducers; development of prototype clothes dryer with ultrasonic vibration as the sole drying mechanism.
- Thermoelectric clothes dryer: Development of experimental prototype using thermoelectric elements in place of electric resistance heating, based on thermodynamic modeling; detailed thermodynamic and psychrometric measurements for design optimization of prototype.
- Heat pump water heater: Conducting experiments for existing open absorption and CO2 heat pump water heating system.
- A2L flammable refrigerant leak studies: Literature review and experimental validation studies of flammable refrigerant charge limits and leaks from building equipment.
