  • Patent number: 9733652
    Abstract: An apparatus control system includes a metabolic amount measurement device measuring a metabolic amount, and an apparatus control device controlling a heating-cooling combination apparatus. A control content storage unit stores thermal sensations and control contents of the heating-cooling combination apparatus. The metabolic amount measured by the metabolic amount measurement device is inputted to an input unit. A metabolic amount storage unit stores a history of the metabolic amount inputted to the input unit before. A calculation unit calculates the thermal sensation using the metabolic amount inputted to the input unit. A correction unit corrects the thermal sensation calculated by the calculation unit using the history of the metabolic amount stored in the metabolic amount storage unit.

  • Publication number: 20090032604
    Abstract: This invention integrates energy saving lighting with energy saving HVAC (Heating, Ventilating and Air Conditioning). This system is termed by the inventor “ILAC” (Integrated Lighting and Air Conditioning). An ILAC system includes light fixtures mounted in a ceiling and, emitting lamp heat into a plenum and visible light into a room. A central computer controls both lighting and HVAC systems. In a COOL mode an HVAC unit cools the room through a supply air duct and return air duct and the lamp heat exits the plenum through an exhaust duct. In a HEAT mode the HVAC heats the room through the same supply air duct, a ceiling-to-plenum duct carries the heated room air into the plenum, and an HVAC return air duct carries room and plenum heat back into the HVAC unit that uses less power to heat the lamp-warmed return air. In a thermostat-controlled OFF mode, warm room air convects through the ceiling duct into the plenum and exhausts through a plenum exhaust duct along with lamp-heated plenum air.

  • Publication number: 20080156891
    Abstract: A refrigerant system includes a controller that enables the system to dehumidify the air in a room without relying on a humidistat and without having to operate the system's compressor and electric heater at the same time. To dehumidify the air, the system's compressor, supply air fan, and outside air damper are controlled in a manner similar to other systems operating in a cooling mode when the room temperature is above a certain setpoint temperature. When the room temperature falls below the setpoint, however, the operation changes significantly. The controller closes the outside air damper, decreases the speed of the fan, and continues operating in this manner until the room temperature decreases to a subcooling temperature limit. The subcooling temperature limit is less than a predetermined limit that is used during the system's normal cooling mode.

  • Patent number: 7159789
    Abstract: A thermostat having a thermostat housing and a rotatable selector disposed on the thermostat housing. The rotatable selector adapted to have a range of rotatable positions, where a desired parameter value is identified by the position of the rotatable selector along the range of rotatable positions. The rotatable selector rotates about a rotation axis. A non-rotating member or element, which may at least partially overlap the rotatable selector, may be fixed relative to the thermostat housing via one or more support member(s). The one or more support member(s) may be laterally displaced relative to the rotation axis of the rotatable selector. The non-rotatable member or element may include, for example, a display, a button, an indicator light, a noise making device, a logo, a temperature indicator, and/or any other suitable device or component, as desired.

  • Patent number: 6898942
    Abstract: A refrigerated appliance that dispenses items includes a power source and a cooling system. Power control circuitry is electrically coupled between a power source (e.g., power cord coupled to a wall outlet) and components (for example, a compressor and one or more circulating fans of the cooling system) of the appliance. A controller, which is operably coupled to the power control circuitry, is adapted to manage the supply of electrical power to such components by intelligently transitioning between a normal-operation mode and at least one power-conserving mode. To achieve efficient power conservation, the controller automatically transitions between the at least one power-conserving mode and the normal-operation mode based upon at least one temperature signal, at least one dispensing event signal, and possibly other data signals supplied to the controller.

  • Patent number: 6745581
    Abstract: The present invention provides systems and methods for temperature control in refrigeration systems, such as beverage coolers, and heating systems, such as coffee dispensers. In an embodiment of the present invention, a control unit of a refrigeration system in accordance with the present invention receives and records activity data such as door openings and/or human presence detection in the vicinity of the refrigeration system, and then establishes the beginning and end times of an energy saving mode for the refrigeration system over a period of time, such as a week. The control unit calculates the time to restart the compressor cycle at the end of the energy saving mode so that the product will be at the correct temperature at the time of first usage. As part of the energy saving function, the lamps and fans in the refrigeration system are controlled independently by the control unit according to the activity data.

  • Patent number: 6726113
    Abstract: A temperature control system utilizes detected occupancy and activity levels to automatically condition a response of an HVAC system to a difference between a setpoint temperature and an actual temperature within a zone. The illustrated example includes an infrared sensor that provides at least one signal indicating the activity and occupancy levels in the zone. A neural network processes the sensor signal to provide an indication of the occupancy and activity levels to a controller. The controller automatically adjusts at least one control parameter of the HVAC system to compensate for changes in the occupancy or activity levels that would affect the temperature comfort setting in the zone.
