| Abstract: | The mathematical model of the decompressor in the operation process was built for the independent developed gas decompressor. The numerical simulation of air conditioning decompressor was performed by using four -step Runge -Kutta method. The response characteristics of the decompressor in the filling, opening and closing processes were analyzed and the comparison of response characteristics with test was also performed. The pressure response curves of the control cavity, output cavity and damping cavity fo... |
