Title: METHOD FOR REGULATING THE ROTATIONAL SPEED OF A COMPRESSOR AS A FUNCTION OF THE AVAILABLE GAS FLOW OF A SOURCE AND REGULATION THEREBY APPLIED
Abstract:
Method for controlling the speed (n) of a compressor (4) with a controller (7) as a function of the available gas flow (Q) comprising the following steps: • - the setting of a desired value (p set ) for the inlet pressure (pin); • - the determination of the, inlet pressure (p in ); • - the determination of the speed (n); • - the control of the speed. (n) of the compressor (4) by reducing or increasing it depending on whether the, ' inlet pressure ( pin ) is less than or greater than the set desired value (p set ) until the inlet pressure ( P in) is equal to the set desired value (p se t); • - the provision of the characteristic data of the compressor (4) relating to the- efficiency and/or the SER as a function of the speed (n) and the inlet pressure ( p in); • - the adjustment of the. desired value (p set ) of the inlet pressure (p in ) on the basis of the aforementioned characteristic data and in such a way that after the aforementioned control of the speed (n) at the adjusted desired value (p set ) of the inlet pressure ( p in), the efficiency of the compressor - is a maximum or the SER is a minimum. Controller applying the method, and compressor comprising a controller.
