Method and apparatus for energy-efficient temperature-based systems management

摘要

A system for load control in an electrical power system is described, wherein one or more temperature-monitoring devices are provided to control operation of a pool pump. When ambient temperatures are relatively high, and thus, electrical power demands from air conditioning systems are relatively high, the temperature-monitoring devices can remove power from the controlled device during the hottest portions of the day. The temperature-monitoring devices can provide power to the controlled devices during the cooler portions of the day. During heat waves or other periods of relatively continuous high heat, the temperature-monitoring devices can schedule power to the controlled devices to reduce overall power demands and to run the controlled devices during the cooler portions of the day when air conditioning electrical loads are reduced. The temperature-monitoring devices can also coordinate operation of the pool pump and a pool heater.

主权项

1. An apparatus for energy efficient operation of a pool pump and heater system, comprising:
a pump; a control system configured to receive water temperature data from water in a pool serviced by said pump; and and a heater that heats said water, said control system calculating a start time to turn on said heater and said pump such that said water will be at a desired temperature at a desired future time, said control system calculating filtration times to run said pump before said start time, said filtration times computed based at least in part on said start time and at least in part on a desired average of filtration time operating over a time period, said control system running said pump during said filtration times, said control system activating said heater at said start timea specified average amount of time over a specified time window so that said pump is operated to provide filtering of the water while taking into account periods of pump operation to run the heater, wherein the specified time window is a sliding window such that the control system operates said pump for at least a specified amount of time over a time window that includes a plurality of days in the past and one or more days projected into the future, and wherein when said control system has deferred operation of the pump entirely for at least one past day within the specified time window, said control system increases the time the pump is to be operated to at least partially catch up on the filtration time missed during deferred operation of the pump in order to meet the specified average amount of time.
