Abstract:
An extended run time device for extending the time that a compressor-based heating, ventilating, and air-conditioning (HVAC) system runs so as to increase energy efficiency of the HVAC system. The extended run time device includes a sensing circuit, a switching device and a processor. Based upon a signal from the sensing circuit, the processor causes the switching device to transmit a proxy control signal to the compressor, thereby causing power to the compressor to be maintained for a time period longer than a time period requested by the temperature control device.
Abstract:
A load-managing electricity service (LMES) system for managing and controlling electricity-consuming loads supplied by a common distribution transformer. The LMES system includes: a communicative distribution transformer (CDT) sensor that includes a transceiver, a sensing circuit and a processor configured to determine whether a power load of the transformer exceeds an upper threshold. The LMES system also includes a load-control device (LCD) configured to communicate with the CDT sensor, and to selectively decrease or increase the power load of the distribution transformer by managing the electricity-consuming leads at consumer premises.
