Abstract：
Establishes a mathematical model and a physical model. In the same operating conditions, compares the results of similar model experiment with that of CFD numerical simulation, and verifies the validity of the simulation method. Based on a practical model of a large underground hydropower station, simulates the temperature distribution and velocity distribution of a workshop in the conditions of various supply air temperature and start-stop control of local air conditioning, which provides the reference for the optimized HVAC design scheme.
