Patent number: 8840376Abstract: The present invention provides a pumping system for moving water of a swimming pool, including a water pump and a variable speed motor. In one example, a target volume amount of water and an operational time period is provided, and the operational time period is altered based upon a volume of water moved. In another example, operation of the motor is altered based upon the volume of water moved. In addition or alternatively, a target flow rate of water to be moved by the water pump is determined based upon the target volume amount and a time period. In addition or alternatively, a plurality of operations are performed on the water, and a total volume of water moved by the pump is determined. In addition or alternatively, an optimized flow rate value is determined based upon power consumption.Type: GrantFiled: March 29, 2010Date of Patent: September 23, 2014Assignee: Pentair Water Pool and Spa, Inc.Inventors: Robert W.

Patent number: 8801389Abstract: Embodiments of the invention provide a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, and a controller in communication with the motor. The controller determines a first motor speed, obtains a reference flow rate, determines a present flow rate, and determines a present power consumption. The controller calculates a difference value between the reference flow rate and the present flow rate, and uses at least one of integral, proportional, and derivative control to generate a second motor speed based on the difference value. The controller attempts to drive the motor at the second motor speed until reaching a steady state condition.Type: GrantFiled: December 1, 2010Date of Patent: August 12, 2014Assignees: Pentair Water Pool and Spa, Inc., Danfoss Low Power Drives A/SInventors: Robert W. Stiles, Jr., Lars Hoffmann Berthelsen, Peter Westermann-Rasmussen, Gert Kjaer, Florin Lungeanu

Patent number: 8602745Abstract: Embodiments of the invention provide a system including a pump, a motor, and a controller. The controller establishes a baseline value of power consumption during a deadhead condition, increases a counter when a current value decreases below the baseline value, and determines a deadhead condition when the counter exceeds a limit. The controller also compares a current value to an immediately previous power consumption value to determine an entrapment condition indicated by a sudden decrease in power consumption.Type: GrantFiled: December 11, 2006Date of Patent: December 10, 2013Assignees: Pentair Water Pool and Spa, Inc., Danfoss Low Power DrivesInventors: Robert W.
