Room temperature, colloquially, denotes the range of air temperatures most people find comfortable indoors while dressed in typical clothing. Comfortable temperatures can be extended beyond this range depending on humidity , air circulation , and other factors.
Also based on the PMV model, this method uses tools such as the ASHRAE Thermal Comfort Tool or the online CBE Thermal Comfort Tool for ASHRAE 55 [2] to evaluate thermal comfort. Users provide operative temperature (or air temperature and mean radiant temperature), air speed, humidity, metabolic rate, and clothing insulation value, and the tool ...
Satisfaction with the thermal environment is important because thermal conditions are potentially life-threatening for humans if the core body temperature reaches conditions of hyperthermia, above 37.5–38.3 °C (99.5–100.9 °F), [11] [12] or hypothermia, below 35.0 °C (95.0 °F). [13]
The most accurate method of evaluating how the environment is affecting the thermal manikin is by calculating the equivalent temperature of the environment, accounting for the effects of radiant heat, air temperature, and air movement. It is necessary to calibrate the manikin based on this before each experiment, as the factor to convert power ...

An airliner fuselage, such as this Boeing 737, forms an almost cylindrical pressure vessel.. Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for humans flying at high altitudes.
Anyone who shares a bedroom is likely familiar with what can sometimes become a bitter battle over the temperature at bedtime. Studies have shown that 50 percent of couples prefer different ...
The first human to fly in a vertical wind tunnel was Jack Tiffany in 1964 at Wright-Patterson Air Force Base located in Greene and Montgomery County, Ohio.. In 1982 Jean St-Germain, an inventor from Drummondville, Quebec, [2] sold a vertical wind tunnel concept to both Les Thompson and Marvin Kratter, both of whom went on to build their own wind tunnels.
