  • Patent number: 10353411
    Abstract: A power supply unit for use with thermostats or other like devices. The power supply unit may keep electromagnetic interference emissions and harmonics at a minimum. A unit may have enough power for triggering a switch at about a cross over point of a waveform of input power to the unit. Power for triggering may come from a storage source. Power for the storage source may be provided with power stealing which require switching transistors which can generate emissions. In-line thermostats using MOSFETS power steal may do the power steal during an ON state (triac, relay or silicon controlled rectifier activated). Gate signals to the transistors may be especially shaped to keep emissions from transistor switching at a minimum. All that may be needed, during an OFF state as a bypass, is a high voltage controllable switch. The need may be achieved using high voltage MOSFETS.

If at least one of motion detectors, each provided to one of the indoor units, starts to detect the presence of a person during suspension of the air conditioning operation, an indoor controller of an indoor unit sums, for each of the motion detectors, time periods in which the presence of the person is detected to obtain a detection time period sum. If any one of detection time period sums, each for one of the motion detectors, reaches a reference value within a predetermined time period, the outdoor controller causes the air conditioner to resume the air conditioning operation.

  • Publication number: 20140263678
    Abstract: An auto changeover mechanism for a thermostat. A heat and cool mode auto changeover with single or crossed setpoints may be an approach for doing a single setpoint auto changeover, an approach that can handle auto changeover with separate heat and cool setpoints that do not require the cool setpoint to always be higher than the heat setpoint, and also an approach that does not necessarily require a dead band between the setpoints. A hysteresis may be associated with switching to the other mode. The thermostat having the auto changeover mechanism may have a display of a mode that automatically changes between heat and cool.

  • Publication number: 20140063721
    Abstract: A chassis for a network storage system contains a first thermal chamber that houses conventional electronic components and a second thermal chamber that houses non-volatile solid state memory such as flash memory. A cooling system keeps the electronics in first thermal chamber below their maximum junction temperature. Meanwhile, a temperature regulating system maintains the solid state memory in the second thermal chamber within a range of a preferred operating temperature selected to extend the lifetime and/or improve the reliability of the solid state memory. Thus, the chassis provides dual zone temperature control to improve performance of the network storage system.

  • Patent number: 8457796
    Abstract: A method and system for predictively controlling environmental conditions of multiple occupancy zones in an occupancy space are provided. Occupancy and environmental conditions of each of the occupancy zones are detected and identified. The detected occupancy is stored in an occupancy database. Patterns of occupancy of each of the occupancy zones are determined using the occupancy database. Future occupancy of the occupancy zones is predicted based on the occupancy patterns of the occupancy zones. The environmental conditions of the occupancy zones are controlled based on the detected occupancy and/or the predicted future occupancy. The environmental conditions of the occupancy zones in the occupancy space are thereby predictively controlled by simultaneously incorporating an occupant's desired settings, existing and historical temperature data within the occupancy space, and weather data.

  • Patent number: 8442694
    Abstract: An air conditioner and a method of controlling the same are disclosed herein. The method of controlling the air conditioner includes receiving an electric power rate information, and distributing an internal air from a first indoor room to a second indoor room to reduce a temperature difference between a plurality of indoor rooms. During periods of peak power rates, costs associated with operating the air conditioner may be reduced by limiting operation of the indoor and outdoor units, while adjusting the temperatures of the indoor rooms by distributing air among the plurality of the indoor rooms.

  • Patent number: 8386082
    Abstract: A cell phone location-based system is described that determines the occupancy of a home and controls home energy consumption such that energy is saved when the home is unoccupied. Occupancy is determined according to cell phone locations, occupant behavior patterns, or burglar alarm status. When an occupant is determined to be returning to their unoccupied home, the heating or cooling apparatus is activated to return the temperature in the home to a comfortable level by the time the occupant arrives.

  • Publication number: 20120080531
    Abstract: A method for evaluating a temperature control equipment of a building. The temperature control equipment is communicatively coupled with a thermostat. The method may comprise calculating an ideal design temperature difference (DTD) for temperature control of the building; calculating an actual DTD associated with the temperature control equipment, the actual DTD being calculated at least partially based on: an equipment off time during a temperature control equipment work cycle, an equipment on time during the temperature control equipment work cycle, an ambient temperature, and a set point temperature of the thermostat; and evaluating the temperature control equipment based on the ideal DTD and the actual DTD, the temperature control equipment being evaluated to determine whether the temperature control equipment is at least one of: oversized for the building, undersized for the building, or generally matches with a temperature control requirement of the building.

  • Patent number: 8010237
    Abstract: The invention comprises systems and methods for ramping setpoints on thermostats controlling HVAC systems. At least one thermostat is located inside a structure and is used to control an HVAC system in the structure. At least one remote processor is in communication with said thermostat and at least one database stores data reported by the thermostat. At least one processor compares the outside temperature at least one location and at least one point in time to information reported to the remote processor from the thermostat. The remote processor ramps the setpoint on the thermostat so as to reduce the average spread between inside temperature and outside temperature in order to reduce energy consumption with affecting comfort. The remote processor takes into account the effect of weather conditions and occupant preferences in determining whether and when to ramp setpoints.
