In a data center, a plurality of racks are cooled by activating a cooling device and opening a controllable partition configured to vary a supply of cooling fluid within a zone of the data center. The zone includes at least one associated rack of the plurality of racks. In addition, the temperature of at least one associated rack is sensed and it is determined whether the sensed temperature is within a predetermined temperature range. Furthermore, the controllable partition is manipulated to vary the supply of the cooling fluid to the zone in response to the sensed temperature being outside the predetermined temperature range.

Oppositely of a temperature measuring surface of an object-to-be-measured 16, a reflecting member 28 is disposed while being spaced by a reflection gap 35 from the temperature measuring surface. The reflecting member 28 is composed of a heat ray reflecting material capable of reflecting heat ray in a specific wavelength band, in a portion including a reflection surface 35a. A heat ray extraction pathway section 30 is disposed through the reflecting member 28 so that one end thereof faces the temperature measuring surface. Heat ray extracted through the heat ray extraction pathway section from the reflection gap is detected by a temperature detection section 34. The heat ray reflecting material is configured in a form of a stack comprising a plurality of element reflecting layers composed of a material having transparent properties to the heat ray, in which every adjacent two element reflecting layers are composed of a combination of materials having refractive indices which differ from each other by 1.1 or more. This makes the measurement be hardly affected by radiation ratio of the object-to-be-measured when temperature of the object-to-be-measured is measured by a radiation thermometer, enables to measure its temperature more correctly irrespective of the surface state thereof, and can simplify configuration of a measurement system.

This invention is a system of transparent or translucent panel units that permit selective transmission of light and solar radiation or glare across the system and can be adjusted and controlled according to a user's varying needs using light-controlling members mounted for rotation about their longitudinal axes. The system can illuminate the interior space by reflected sunlight, conducting both light from the brightest part of the sky and low-angle sunlight efficiently into the interior space, and also shading or deflecting the intense light found when the sun is at high elevation. Alternatively, the amount of a selected portion of the radiation spectrum passed through the system can be set at will, and can be amplified to allow increased light passage and transmission.
