20120286051TAMPER 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
20090032604Energy 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

20130161402METHOD OF PREVENTING EXHAUST GAS FROM LEAKING OUT OF FOOD WASTE DISPOSER - A method of preventing exhaust gas from leaking out of a drying furnace is disclosed. In the method, the temperature of an exhaust passage and the temperature of a heater are measured, and turning on/off the heater is controlled in response to the measured temperatures. The present invention can be applied to all kinds of apparatuses having drying furnaces which are heated by heaters and thus generate the exhaust gas and can effectively prevent exhaust gas from leaking out of the apparatuses. Furthermore, the present invention can be more effectively applied to food waste disposers which heat food waste containing a large amount of water.
