Simulation and Experimental Study of the Characteristic Parameters of an Aircraft Cabin Temperature Control Valve
Source abstract
Abstract
The temperature control valve system is essential to an aircraft. This study proposes a temperature control valve system in which the cold and hot gas exchange heat through the heat exchanger without mixing to cool the hot gas. The purpose is to maintain the stability of gas flow and temperature at the outlet of the hot path. First, a mathematical model of the temperature control valve is established, and the feasibility of the method is theoretically analyzed. After that, the temperature control valve model is meshed in Ansys, finite element analysis is performed, and the factors that may affect the outlet temperature of the hot path are qualitatively analyzed. A characteristics test experiment for the designed temperature control valve is compared with simulation results to verify the system’s feasibility. A steady-state model of the heat exchanger was obtained by a 25-point orthogonal experiment. Taking the predicted hot-side flow rate of the heat exchanger under different flow conditions as input, the heat exchanger model was fitted and dynamically analyzed, which confirmed the feasibility of PID adaptive control of the temperature control system.
