Abstract

An energy management system for a home network is provided. The energy management system includes one or more power consuming devices, including at least a pool pump system having a motor and a filter with a filtration cycle, a central controller operatively connected to the power consuming devices and configured to receive and process a signal indicative of the current state of an associated utility, including at least a peak demand state and an off-peak demand state, and a display. The central controller is configured to operate the pool pump system in one of a plurality of operating modes, including at least a normal operating mode and an energy savings mode, and to provide pool pump usage information to a user via a user interface on the display.

Claims

1. An energy management system for a home network comprising:

one or more power consuming devices, including at least a pool pump system comprising a motor, a filter with a filtration cycle, and a bypass valve configured to redirect a portion of water inflow around the pool pump system without entering the filter;

a central controller operatively connected to the power consuming devices and configured to receive and process a signal indicative of the current state of an associated utility, including at least a peak demand state and an off-peak demand state; and

a display;

wherein said central controller is configured to operate the pool pump system in one of a plurality of operating modes, including at least a normal operating mode and an energy savings mode, and to provide pool pump usage information to a user via a user interface on said display; and

said central controller is operatively connected to the bypass valve to divert a portion of the water inflow around the pool pump system in the energy savings mode to reduce the energy consumed by the pool pump system.

2. The energy management system according to claim 1, wherein said controller is configured to operate said pool pump system primarily in off-peak energy demand periods.

3. The energy management system according to claim 1, wherein said power consuming devices further includes at least one HVAC.

4. The energy management system according to claim 3, wherein said central controller is configured to operate said pool pump system according to a schedule opposite that of said HVAC.

5. The energy management system according to claim 1, wherein said user interface is configured to receive operating instructions for the pool pump system from said user.

6. The energy management system according to claim 5, wherein said operating instructions include at least one of a home setting, an away setting, a “

start now”

setting, and a low-flow setting.

7. The energy management system according to claim 1, wherein the pool pump system further includes a control valve capable of opening and closing in various degrees to increase and decrease flow restriction.

8. The energy management system according to claim 1, wherein the pool pump system further includes a dual-stage pump having each of a high- and low-flow condition, wherein said central controller is configured to switch from a high-flow to a low-flow condition in response to a signal indicative of a peak demand period.

17. The energy management system of claim 1 wherein the central controller is further configured to receive a signal of an upcoming peak demand period and present, on the display, possible cost implications of running the pool pump during the upcoming peak demand period.

9. A method for reducing the peak power consumption of a pool pump system in an energy management system including one or more power consuming device, a central controller configured to receive and process a signal indicative of the current state of an associated utility, the utility state being at least one of a peak demand period and an off-peak demand period, and a pool pump system having a motor and filter with a filtration cycle, said method comprising the steps of:

a) receiving and processing a utility state signal into said central controller;

b) at least one of operating and scheduling to operate said pool pump system such that the pool pump system operates primarily during an off-peak demand period; and

c) operating said pool pump system in a reduced-flow condition during periods of peak demand, including implementing a bypass valve and re-circulating water around the pool pump system and back into an associated pool without entering the filtration cycle.

10. The method according to claim 9, further including tracking the usage of each power consuming device in said system and scheduling the pool pump system operation at times usage of the power consuming devices is low.

11. The method according to claim 9, wherein the at least one power consuming device includes an HVAC, wherein the pool pump system is scheduled to operate when the HVAC is inactive.

12. The method according to claim 9, wherein said pool pump system includes a “

start now”

setting, enabling a user to activate the filtration cycle at any moment.

13. The method according to claim 10, wherein bypassing the filtration cycle maintains water circulation without filtration.

14. The method according to claim 9, wherein operating in a reduced-flow condition includes implementing a control valve and rotating the valve to block a water flow passageway in various degrees.

15. The method according to claim 9, further including adjusting the speed of said motor driving said pool pump system.

16. The method according to claim 9, wherein operating in a reduced-flow condition includes implementing a dual-stage pump and switching a pool pump flow condition from that of a high flow to a low flow.
