What Does
Dry Bulb Temperature Mean?
Dry bulb temperature (DBT) can be recorded when an ordinary thermometer is exposed to the atmosphere and is shielded from radiation and moisture. Temperature recorded in this manner does not vary with the moisture content in the air.
This type of temperature measurement is also referred to as the atmospheric temperature and can be expressed in either Celsius (C), Fahrenheit (F), or Kelvin (K).
Safeopedia Explains Dry Bulb Temperature
In the context of safety and health, dry bulb temperature can be used to express a component of thermal comfort. It is the most common and easiest indicator that people can relate to. Thermal comfort is significant because when people are dissatisfied with their thermal environment, not only is it a potential health hazard, but it also impacts their ability to function effectively, their satisfaction at work, and the likelihood they will remain a customer.
Dry bulb temperature readings are also one of the indicators used to measure heat stress.
In addition, dry bulb temperature can be used to determine relative humidity. The difference in temperature between dry bulb and wet bulb readings is used when referring to a humidity chart, which is then used to express relative humidity.
