Real-time monitoring of an energy characteristic of a building such as an energy performance of the building or a carbon offset of the building is performed by first computing a heat transfer coefficient of the building from nighttime steady-state thermal load data of the building and from nighttime steady-state indoor and outdoor temperature data of the building. A thermal inertia of the building is then computed from nighttime transient indoor temperature data of the building and nighttime transient thermal load data of the building. During daytime, a solar radiation gain coefficient is computed from daytime thermal load data, daytime indoor and outdoor temperature data, incident solar radiation data, and the heat transfer coefficient. The energy characteristic of the building is then estimated in real time from the heat transfer coefficient, the thermal inertia, and the solar radiation gain coefficient.

A system and method for controlling the cooling fan within an electronic display based on the amount of ambient light present. An ambient light sensor is used to measure the amount of ambient light which is contacting the display. To anticipate a temperature rise and lower the thermal inertia of the display, the fan speed is increased when high ambient light levels are measured at the exterior of the display. The ambient light sensor data may be used to apply a temperature correction factor to a temperature sensor within the display. Alternatively, the ambient light sensor data may be used to apply a fan speed correction factor to a desired fan speed (calculated based on a temperature sensor within the display). Multiple systems or methods can be used simultaneously within the display to cool several components which may heat and cool at different rates relative to one another. The various systems can have similar or different logic depending on the amount of cooling needed and the manner in which the cooled-components produce / absorb heat.

A drum-type rotor carries an annular row of moving blades having root portions held within a slot in the periphery of the rotor. A turbine casing surrounds the rotor and carries a static blade assembly with an annular row of static blades which, together with the annular row of moving blades, constitutes an impulse turbine stage. The static blade assembly has a radially inner static ring confronting a periphery of the rotor with a seal acting therebetween. The static blade assembly has an outer static ring which has a substantially greater thermal inertia and stiffness then the inner static ring and is capable of sufficient radial sliding relative to the casing so as to accommodate relative thermal expansion and contraction of the outer static ring and the turbine casing.

The embodiment of the invention discloses a method and system for controlling the temperature of the process hot air of a warming and humidification device. The method includes injecting steam flow into a circulation wind pipe by adjusting a steam jet firstly, and adjusting, as an auxiliary means, the temperature of the process hot air by adjusting the steam flow amount of a circulation wind heater. The method no longer mainly depends on the circulation wind heater, thereby solving the problem that the adjustment of the temperature of process hot air is severely lagged behind due to the influence of the thermal inertia of radiating tubes of the circulation wind heater. No fresh air is needed for controlling the temperature of the process hot air, which prevents fluctuation of air flow pressure of the process hot air in a roller due to change of supplemented fresh air. The problems of unstable travelling speed and water absorption rate of materials in the roller also can be prevented.

The invention relates to a radiant heater for heating the building material in a laser sintering device and to a laser sintering device comprising a radiant heater of this type. The radiant heater comprises a flat heat-emission element (113, 213, 313), which is characterised in that it consists of a material with low thermal inertia and a thermal diffusivity preferably in excess of 1.5 10-4 m2 / s and preferably a thickness less than or equal to 2 mm.

The process of active DPF regeneration requires that the DPF be brought to regeneration temperatures in excess of 550° C. to 600° C. for a period of time sufficient to accomplish soot burnoff in the DPF. Similarly, during cold start up it is desirable to bring the catalyst to light off temperature as soon as possible. The large thermal inertia of one or more turbochargers delays the exhaust gas at the DPF from reaching critical temperature quickly. The incorporation of a low thermal inertia, insulated, turbocharger bypass duct avoids thermal energy loss from exhaust gas to the turbine housing and shortens the time for the DPF to reach critical temperature for active DPF regeneration, or in the case of a catalytic converter, shortens time for catalyst to reach light off temperature.

The composite wall structure gives full play to the heat insulation effect of the heat insulation layer and the heat storage and temperature regulation effect of the phase change layer to improve the thermal inertia of the wall body greatly. The composite wall structure has stable performance and is convenient in construction and energy-saving reconstruction of old buildings to achieve the effects of high efficiency and environmental protection.
