Abstract: Apparatus, including a pump system controller, features a signal processor or processing module configured at least to: receive signaling containing information about pump differential pressure, flow rate and corresponding power data at motor maximum speed published by pump manufacturers, as well as instant motor power and speed, for a system of pumps arranged in a multiple pump configuration; and determine corresponding signaling containing information about instant pump differential pressure and flow rate for the system of pumps arranged in the multiple pump configuration using a combined affinity equation and numerical interpolation algorithm, based upon the signaling received.

Abstract: Apparatus for providing variable speed pump control in a hydronic pump system having a system flow and pressure requirement, featuring a signal processor or processing module configured to: receive signaling containing information about a system characteristic curve, a system flow and pressure requirement for the hydronic pump system, and real time changes by a pump operator to at least one control parameter to adjust the performance of the hydronic pump system; and determine corresponding signaling containing information about a design/redesign of at least one pump, system or control curve to adjust the performance of the hydronic pump system to correspond with the system flow and pressure requirement of the hydronic system, based upon the signaling received.

Inventor： Andrew A. Cheng , Kyle D. Schoenheit
Abstract: A pump controller features a signal processor configured to respond to signaling containing information about three corresponding discrete arrays with respect to a discrete motor speed for each system position at a motor speed derived from 3D discrete distribution surfaces of motor power, pump differential pressure and flow rate by respective numerical interpolations; and determine corresponding signaling containing information to control a pump, or pumps in a system of pumps, or a system of pumps based upon a corresponding pump differential pressure and flow rate at the motor speed for a corresponding power reading value determined using a numerical interpolation of the three corresponding discrete arrays, the signaling received. The signal processor is configured to provide the corresponding signaling as control signaling to control the pump, or the pumps in the system of pumps, or the system of pumps.

Abstract: The present invention provides a numerical affinity pump sensorless conversion signal processing technique, e.g. based upon processing the pump differential pressure, flow rate and power at pump maximum speed published by pump manufacturers, as well as the pump affinity law in order to obtain instant pump differential pressures and flow rate directly and numerically. The sensorless converter technique may be applied to any form of pump characteristics distributions simple or complicated, since there is no need to reconstruct and to solve any pump and system characteristics equations. As a result, the computation accuracy is significantly improved.
