2. Thermal comfort - Wikipedia

   en.wikipedia.org/wiki/Thermal_comfort

   The results are displayed on a psychrometric or a temperature-relative humidity chart and indicate the ranges of temperature and relative humidity that will be comfortable with the given the values input for the remaining four parameters. [44] The PMV/PPD model has a low prediction accuracy. [45]

3. File:Temperature-relative humidity chart - PMV method.pdf

   en.wikipedia.org/wiki/File:Temperature-relative...

   The representation is made on a temperature-relative humidity, instead of a standard psychrometric chart. The comfort zone in blue represents the 90% of acceptability, which means the conditions between -0.5 and +0.5 PMV, or PPD < 10%.

4. ASHRAE 55 - Wikipedia

   en.wikipedia.org/wiki/ASHRAE_55

   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 ...

5. File:Psychrometric chart - PMV method.pdf - Wikipedia

   en.wikipedia.org/wiki/File:Psychrometric_chart...

   English: This psychrometric chart represents the acceptable combination of air temperature and humidity values, according to the PMV/PPD method in the ASHRAE 55-2010 Standard. The comfort zone in blue represents the 90% of acceptability, which means the conditions between -0.5 and +0.5 PMV, or PPD < 10%.

6. Humidity - Wikipedia

   en.wikipedia.org/wiki/Humidity

   Although humidity is an important factor for thermal comfort, humans are more sensitive to variations in temperature than they are to changes in relative humidity. [31] Humidity has a small effect on thermal comfort outdoors when air temperatures are low, a slightly more pronounced effect at moderate air temperatures, and a much stronger ...

7. Psychrometrics - Wikipedia

   en.wikipedia.org/wiki/Psychrometrics

   A chart is valid for a given air pressure (or elevation above sea level). From any two independent ones of the six parameters dry bulb temperature, wet bulb temperature, relative humidity, humidity ratio, specific enthalpy, and specific volume, all the others can be determined.

9. Operative temperature - Wikipedia

   en.wikipedia.org/wiki/Operative_temperature

   Operative temperature is used in heat transfer and thermal comfort analysis in transportation and buildings. [10] Most psychrometric charts used in HVAC design only show the dry bulb temperature on the x-axis(abscissa), however, it is the operative temperature which is specified on the x-axis of the psychrometric chart illustrated in ANSI/ASHRAE Standard 55 – Thermal Environmental Conditions ...
