    Abstract: A signal processor receives signaling containing information about flow rates from sensorless converters in zone circulators in heating/cooling zones controlled by temperature sensors in a hydronic heating system in order to derive an adaptive pressure set point to meet the flow rates requested by the heating/cooling zones using an adaptive system and flow control curve equation, the signaling containing information about total flow rates requested by the zone circulators; determines desired pump speeds for the zone circulators to meet temperature requirements in heat zones; provides corresponding signaling containing information about the desired pump speeds; and/or determines the adaptive pump control curve equation based upon an adaptive system curve and as a moving maximum system flow rate depending on an adaptive pressure set point, a system flow rate requested by temperature loads, a minimum pressure at no flow, a control curve setting parameter, and an adaptive moving maximum flow and pressure.

    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.

    Abstract: A discrete valve flow rate converter is provided to obtain a system flow through a valve in a dynamic hydronic pumping system, e.g., based on signaling containing information about the valve's differential pressure and the valve's hydronic characteristics calibration data. The discrete valve flow rate converter resolves the valve system flow rate directly and accurately with the valve's open position and the corresponding valve differential pressure signals associated therewith. The discrete valve flow rate converter may be applied to all kinds of valves as long as their open position and differential pressure associated with is available, e.g., including implementations for control valve applications, e.g., where the valve open position is controlled automatically and accurately, as well as implementations either for pumping system pressure controls with the flow rate known, such as adaptive hydronic system pressure controls, or as an alternative to sensorless pump monitoring and control.
