Tian You was a visiting student scholar at the University of California, Berkeley for one year. She obtained her MEng and PhD from Tsinghua University in China. Her doctoral dissertation focused on the modeling of Ground heat exchanger (GHE) and the performance improvement of Ground-coupled Heat Pump System (GCHP).
She proposed a general model to fast and accurately calculate the heat transfer of different GHEs, like boreholes, energy piles, energy walls and energy tunnels, based on the response factors. To solve the soil thermal imbalance of GCHP in cold regions, she developed a heat compensation unit combining air source thermosyphon and heat pump to realize the efficient seasonal energy storage from air to soil.
Research interests:
- Soil thermal imbalance of ground coupled heat pumps
