When the detected temperature by the second room-temperature detector has raised above a second reference temperature which is set higher than the first reference temperature, the operation is stopped on receiving an off-command from the thermostat. The room heater is controlled to raise a set temperature by a predetermined value if it does not receive the off-command by passing of a first predetermined period of time after having received the on-command or if the detected temperature detected by the first room-temperature detector has been at the set temperature or higher without receiving the off-command for a second predetermined period of time. | 05-21-2015 |
| 20160004263 | GAS DISTRIBUTION SYSTEM WITHIN TEMPERATURE DIFFERENTIATED ENVIRONMENTS - Electrical power is provided to power consuming, heat-exhausting devices by multiple gas-fueled electrical power sources located near such devices. Exhaust heat from such devices is utilized as intake cooling air for the gas-fueled power sources, thereby excluding them from cooling capacity requirements. The gas piping delivering gas to gas-fueled power sources is positioned so as to be within hot aisles comprising exhaust heat. The gas piping is located up high for lighter than air gasses and near the floor for heavier than air gasses, with leak detection located nearby. Additionally, gas piping is externally coated with material that visually indicates a leak. By locating gas piping in the hot aisle, exhausted heat increases temperature and, thereby, pressure of the gas, resulting in more efficient gas distribution through the piping and preventing valve freezing. Furthermore, the gas piping is located after potential ignition sources in the airstream. | 01-07-2016 |
