Abstract

A Process and Interface to reduce the energy required to operate a swimming pool pump. The process improves the conventional process by causing the pump to vary its operation based on variable filter loading conditions. The process uses a flow sensor to send a signal to the interface which then signals a variable frequency drive to increase or decrease the speed of the pump motor in compliance with user programmed flow. The pump operates at reduced energy until the filter load increases due to captured debris. As the filter load increases, the pump speed increases.

Claims

1. ). An energy reduction process for swimming pool circulation systems having a pump, filter, flow sensor, variable frequency drive and interface comprising:

a flow sensor located away from the interface; and

a signal cable to connect said flow sensor with said interface, wherein;

said interface receives a signal from said flow sensor;

said interface has a program to interpret said signal; and

said program will compare said signal to program parameters; and

a signal cable connecting said interface with said variable frequency drive;

wherein;

said interface program sends a signal to said variable frequency drive to control the functions of said pump, therefore;

said pump operates using the minimum energy required throughout the loading cycle of said filer.
