SYSTEM AND FLOW ADAPTIVE SENSORLESS PUMPING CONTROL APPARATUS FOR ENERGY SAVING PUMPING APPLICATIONS

摘要

FIELD: control; regulation.;SUBSTANCE: group of inventions relates to the operation and / or control of a pump of water heating systems. In the method, the signal processor receives the flow rate signaling information from the sensorless converters in zone circulators in heating / cooling zones controlled by temperature sensors to extract the adaptive pressure set point to meet the flow rates requested by the heating / cooling zones. It uses an adaptive system and a flow control curve equation. Also the signaling contains information about total flow rates requested by the zone circulators. Further, the processor determines the required speeds of operation of these circulators in order to meet the temperature requirements in the heat zones, based on the received signaling.;EFFECT: inventions are aimed at providing the pressure in the system required for the flow rate requested in the system with more economical energy consumption.;22 cl, 4 dwg
