Einfluss von dynamischen Durchflusskoeffizienten auf das Druckdifferenzkonzept

S. Brandt, M. Kriegel

Abstract: This paper investigates the requirements for maintaining the pressure in clean rooms and describes the theoretical principles for the calculation of volume flows as a function of pressure losses. With the aid of 1D simulation tools it is illustrated that pressure changes and backflows arise due to disturbances, such as door openings. In order to prevent these effects great effort is expensed in practice. A solution might be the adaption of new door-control methods, which require more detailed information on pressure exponents and flow coefficients. The focus of this paper is to study the dynamic resolution of these operating sequences and to integrate them into models to enable a more accurate mapping of the control processes..
