<p>It comprises taking pressure measurements in a point previous to the consumption points by means of a piece of control equipment and performing the following steps in sequence:
a) acquiring a successive series of supply pressure values (Pi) measured in said previous point;
b) varying the pump rotating speed in response to a pressure variation detected in said previous point;
c) detecting that at least two of said pressure values (P i1 ), (P i2 ) measured in said previous point change (increase or decrease) and obtaining a curve of demand (10) by calculating the coefficients of a known mathematical function descriptive of said curve of demand, making said coefficient calculations from said measured pressure values (P i1 ), (P i2 ) and of corresponding calculated flow rate values;
d) determining a consumption point (12) by intersecting the curve of demand with the y-axis and
e) adopting a pump rotating speed providing a pump setpoint pressure, depending on said consumption point (12) determined in step d),
restarting steps b) to e) in the event of another pressure variation in the demand.</p> |
