Management and control method of a pressurization system

A management and control method for at least one operation parameter of a pressurization system (1) operated by an electric motor (2), the method comprising a preliminary step of storing of nominal operation parameters of said pressurization system (1) in a summary portion of a control electronic unit (4) of said pressurization system (1), and further comprising the steps of:

• detection of an operating pressure value at a delivery duct (8) of said pressurization system (1), by means of a single pressure sensor (10);
• estimation of a hydraulic flow rate and a hydraulic head by means of an algorithm which is implemented in a control software based on said operating pressure value detected by means of said single pressure sensor (10);
• estimation of a motor rotation speed (2) of said pressurization system (1) based on said operating pressure value and on the number of blades (Z) of the impeller of said pressurization system (1);
• processing of an on/off signal of said pressurization system (1) as a result of said estimation;
• wherein said signal processing step comprises an updating step of the value of a nominal hydraulic head of said nominal functional parameters of said pressurization system (1), starting from said operating pressure value and from said motor rotation speed;
• wherein said signal processing step comprises a step of calculating an optimal value of input and suction hydraulic head of said pressurization system (1), within a reference value range;
• wherein said signal processing step comprises a step of calculating a pressure variation between said input and suction hydraulic head and said nominal hydraulic head and of a relative optimization of switch-on time of said pressurization system (1) as a function of said on/off signal;
• wherein said step of calculating an optimal value of an input and suction hydraulic head of said pressurization system (1), comprises the steps of:
• setting of initial pressure parameters of said pressurization system (1);
• calibration of said pressurization system (1) by means of an iterative process of comparison between a weighted difference in operating hydraulic head and a pre-set reference value, said calibration step being repeated after the switching off;
• identification of a value of said reference input and suction hydraulic head and of a minimum energy consumption condition in a pre-set time period.
