Energy reduction process and interface for open or closed loop fluid systems with or without filters

#Not Applicable

#Not Applicable

#This invention pertains to the field of pumping fluids. While this process and interface can be used on a variety of applications, a commercial swimming pool is the clearest example of the use and will be used for this specification. The use of swimming pools as an example is strictly for illustration purposes only and should not be construed as to limit the use of this invention to swimming pools.

#FIG. 1: A concept of the front panel of the interface. The interface may have a touch screen as shown or could have an LCD display with “soft keys” mounted on the outside of the enclosure. The housing is non-metalic NEMA 4, approximately 8″×6″×4″

#FIG. 2: Process Performance Comparison Charts. FIG. 2A illustrates the performance of the conventional process and FIG. 2B illustrates the performance of the improved process. The graphs show the relative comparison. In the conventional process, as the filter load increases, the flow decreases, but the pump speed and energy consumption remain relatively constant. In the improved process, pump speed starts off lower and increases as the filter load increases while the flow remains relatively constant. In the improved process, the % load equals the cube of the % speed (90% speed=72.9% load). The effect is that the pump performance curve dynamically changes to meet the dynamic changes in the filter demand. Beyond the energy reduction, the cavitation at low TDH is eliminated.

#FIG. 3: Conventional Swimming Pool Process Block Drawing. This drawing shows the major components of a conventional swimming pool circulation process.

#The first component of the invented Process and Interface is the interface. The following specifications detail the interface and its operation.
