The new analysis is based on recent research showing that hot weather's most deadly effects for humans come from a combination of high temperature and high humidity, which is measured by a reading known as wet-bulb temperature
recordings take into account humidity in addition to standard temperature, with a 35AC wet-bulb temperature
considered as the limit of human survivability.
Other than measuring and detecting air quality, the dust particle counter possess additional feature of measuring wet-bulb temperature
, humidity, dew point temperature, and air temperature as well.
This threshold corresponds to a wet-bulb temperature
of about 35[degrees]C (95[degrees]F)--conditions associated with, for example, a dry-bulb temperature of 40[degrees]C (104[degrees]F) and a dewpoint temperature near 33.5[degrees]C (92.3[degrees]F).
Since these temperature bin data are based on hourly weather data as opposed to daily averages, they are more accurate than degree-day calculations (Al-Homoud 2001) and able to perform latent load calculations in addition to sensible load calculations due to the availability of wet-bulb temperature
data (Papakostas and Sotiropoulos 1997).
Hot weather's most deadly effects result from a combination of high temperature and high humidity, called a wet-bulb temperature
. A temperature of 94 degrees Fahrenheit (34.4 degrees Celsius) and 80% humidity produces a wet-bulb or afeels likea temperature of 129 degrees Fahrenheit (31 degrees Celsius) on the NOAA National Weather Service Heat Index.
The cooling coil supply air approach to entering cooling water temperature is an important component of the total approach of supply air temperature to outdoor wet-bulb temperature
. Coil selection balances a number of factors, including construction economy, energy efficiency and space requirements.
And, [T.sub.wbi] is the wet-bulb temperature
of the entered (forced) air.
The researchers rely on a method of measuring atmospheric conditions known as wet-bulb temperature
, which describes the extent to which evaporation and ventilation can reduce an object's temperature.
Meteorological data of dry-bulb temperature, wet-bulb temperature
, relative humidity, and temperature humidity index (THI) were significantly different by time (p < 0.01) (Table 1).
