The dry-bulb temperature (DBT) is the temperature of air measured by a thermometer freely exposed to the air but shielded from radiation and moisture. DBT is the temperature that is usually thought of as air temperature, and it is the true thermodynamic temperature. It indicates the amount of heat in the air and is directly proportional to the mean kinetic energy of the air molecules. Temperature is usually measured in degrees Celsius (°C), Kelvin (K), or Fahrenheit (°F). Unlike wet bulb temperature, dry bulb temperature does not indicate the amount of moisture in the air. In construction, it is an important consideration when designing a building for a certain climate. Niall called it one of "the most important climate variables for human comfort and building energy efficiency."〔Nall, D. H. (2004-11). Looking across the water: Climate-adaptive buildings in the United States & Europe. In ''The Construction Specifier'', 57, 50 – 56.〕 DBT is an important variable in Psychrometrics, being the horizontal axis of a Psychrometric chart. == See also == * Psychrometric chart * Wet-bulb temperature * Hygrometer * Atmospheric thermodynamics 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dry-bulb temperature」の詳細全文を読む スポンサード リンク
