• Operative temperature , also known as Dry resultant temperature, or Resultant temperature, is defined as a uniform temperature of a radiantly black enclosure in which an occupant would exchange the same amount of heat by radiation plus convection as in the actual nonuniform environment. Some references also use the terms 'equivalent temperature" or 'effective temperature' to describe combined effects of convective and radiant heat transfer. In design, operative temperature can be defined as the average of the mean radiant and ambient air temperatures, weighted by their respective heat transfer coefficients. The instrument used for assessing environmental thermal comfort in terms of operative temperature is called a eupatheoscope and was invented by A. F. Dufton in 1929. Mathematically, operative temperature can be shown as;where,= convective heat transfer coefficient= linear radiative heat transfer coefficient= air temperature= mean radiant temperatureOrwhere,= air velocityand have the same meaning as above.It is also acceptable to approximate this relationship for occupants engaged in near sedentary physical activity (with metabolic rates between 1.0 met and 1.3 met), not in direct sunlight, and not exposed to air velocities greater than 0.20 m/s (40 fpm). where and have the same meaning as above.
• 作用温度(さようおんど 英Operative Temperature:OT)とは効果温度ともいい、人体に対する温熱環境を評価する指標のひとつである。気温が同じ室内であっても、壁面温度と周囲気流の状態により体感温度は違う。これを加味し、周囲壁面との放射熱伝達と周囲気流との対流熱伝達と同じ量の熱交換をおこうなうような均一温度の閉鎖空間での仮想気温が作用温度である。人体の発熱は評価されないため、気流による冷却効果は評価できない。そのため、この指標は暖房時に用いられる。
