| 20090032604 | Energy saving integrated lighting and HVAC system - 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. Optionally, plenum exhaust duct may include a radiator to transfer plenum heat to pre-heat water entering a remote hot water heater. | 02-05-2009 |
| 20090159715 | VORTEX-BASED TEMPERATURE CONTROL SYSTEM AND METHOD - A vortex-based temperature control system comprises a test chamber configured to receive a test article therein, a sensor disposed within the test chamber for detecting a temperature within the test chamber, a first vortex tube coupled to the test chamber for providing a heating airflow to the test chamber, and a second vortex tube coupled to the test chamber for providing a cooling airflow to the test chamber. The system also comprises a temperature controller coupled to the sensor and configured to control an airflow delivered to the first and second vortex tubes to obtain a desired temperature setting within the test chamber. | 06-25-2009 |
| 20120080531 | THERMOSTAT CONFIGURED FOR PROVIDING EVALUATION OF A TEMPERATURE CONTROL EQUIPMENT AND METHOD THEREOF - 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. | 04-05-2012 |
| 20120286051 | TAMPER PROOF THERMOSTAT THAT LIMITS TEMPERATURE CONTROLS - A thermostat includes: a controller adapted to control the function of an associated HVAC system; and user controls adapted to provide instructions to the controller including selecting between heating functions and cooling functions, wherein the controller is limited by a maximum temperature when heating functions are selected and limited by a minimum temperature when the cooling functions are selected, wherein the maximum temperature is a lower temperature than the minimum temperature. | 11-15-2012 |
| 20140263678 | MULTI-MODE AUTO CHANGEOVER SYSTEM - 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. | 09-18-2014 |
| 20140374496 | NEED IDENTIFYING DEVICE, AIR-CONDITIONING CONTROLLING SYSTEM, NEED IDENTIFYING METHOD, AND AIR-CONDITIONING CONTROLLING METHOD - A need identifying device is provided with a need storing portion that receives, from an informant, a need pertaining to the surrounding environment, an environment state variable controlling portion that calculates an environment state variable for indicating the state of the surrounding environment of the informant based on an environment element measured value collected from a space occupied by the informant, and calculates, from the environment state variable, a dissatisfaction level for the surrounding environment of the informant, and an identification processing portion that identifies, based on the dissatisfaction level, a need from the informant as a temporary need or as a persistent need. | 12-25-2014 |
