Normal temperaturetemperatureperhapsroom temperature, generally defined as 25 ℃.Chemical processAMB is commonly used inambiance。In China, the normal temperature in engineering is 20 ℃, which is the temperature in spring and autumn in most parts of China, such as the circulating water temperature (natural water temperature).
AMB is commonly used in chemical process, namely ambiance.
Normal temperature is also called normal temperature or room temperature, which is generally defined as 25 ℃.thermodynamicsupperStandard temperatureIt is calculated by 0K, and the starting point of all enthalpies and entropies is 0K.

In China, the normal temperature is calculated at 20 ℃（RussiaThe normal temperature of the project is 10 ℃), which is the temperature in spring and autumn in most parts of China, such as the circulating water temperature (natural water temperature).Another exampleBlowerDesign temperatureIt is 20 ℃.The normal temperature in the boiler design calculation sheet is also 20 ℃.
The normal temperature in water treatment is slightly different, some are 15 ℃, some are 20 ℃, and some are 25 ℃ (such assolubilityandSolubility product, different materials and methods), andIonization of waterThe temperature is 22 ℃.
HVACThere are several kinds of professional normal temperature, such as 10 ℃ for unmanned rooms and 18 ℃ for occupied rooms.
In the chemical system, the design temperature of normal temperature is more than - 20~200 ℃.
In the pharmaceutical industry, normal temperature refers to 10-30 ℃, and imported ones also refer to 15-25 ℃.
