Abstract (en)
[origin: EP2910865A1] The object of the invention is a system for controlling a fan insufflating air into a protected space, especially in fire ventilation for the protection of escape routes, comprising a controller equipped with a processor with a high computational power and a memory, designed and configured to control the said fan by setting frequency U of the inverter controlling the motor of said fan and connected to this inverter, and in addition connected to a pressure sensor for measuring pressure difference P between the protected space and a reference pressure, characterised in that the said controller is configured and programmed to perform the following steps: a) registering, in the memory of the controller, parameters of the fan, determined in time; b) registering, in the memory of the controller, parameters of the protected space, variable in time; c) determining the value of parameter a(k) at current moment k as a function of a(k)=P(k) / U2(k); d) determining the value of control U(k+1) at a subsequent moment of time k+1, by solving the task of non-linear optimisation by means of an iterative method, the feasible point of the iterative method being assumed as Ustart(k+1)=Sqrt(P(k) / a(k)); e) setting the so determined value of control U(k+1) as a frequency of the inverter controlling the fan motor. The object of the invention is also a method for controlling a fan insufflating air into a protected space, especially in fire ventilation for the protection of escape routes.
