Observera att Wet Bulb temperatur inte är den enda innebörden av WBT. The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked cloth (wet-bulb thermometer) over which air is passed. At 100% relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature); at lower humidity the wet-bulb temperature is lower than dry-bulb temperature because of evaporative cooling. bulb verb noun bʌlb, boʊlb + grammatik Any solid object rounded at one end and tapering on the other, possibly attached to a larger object at the tapered end 2020-04-18 · By definition, wet-bulb temperature is the lowest temperature a portion of air can acquire by evaporative cooling only.

The efficiency of cooling towers relies on accurate and reliable outdoor wet bulb temperature instruments. Shortcomings can result in cooling tower overuse, leading not only to increased water and energy usage but also reduced lifetime of fans and pumps.

Wet bulb temperature is the lowest temperature to which air can be cooled by the evaporation of water into the air at a constant pressure. It is therefore measured by wrapping a wet wick around the bulb of a thermometer and the measured temperature corresponds to the wet bulb temperature. The dry bulb temperature is the ambient temperature. Wet-bulb globe temperature (WBGT) is nowadays the most widely used index of heat stress, yet many users appear to be unaware of its history and its limitations. HISTORY OF WBGT: WBGT was invented and first used during the 1950s as one element in a successful campaign to control serious outbreaks of … The measured wet bulb is a function of relative humidity and ambient air temperature. Wet bulb temperature essentially measures how much water vapor the atmosphere can hold at current weather conditions.
