  2. Atmospheric radiative transfer codes - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_radiative...

    Radiative transfer codes are used in broad range of applications. They are commonly used as forward models for the retrieval of geophysical parameters (such as temperature or humidity). Radiative transfer models are also used to optimize solar photovoltaic systems for renewable energy generation. [1] Another common field of application is in a ...

  3. 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]

    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%.

  5. Thermo-hygrograph - Wikipedia

    en.wikipedia.org/wiki/Thermo-hygrograph

    A thermo-hygrograph. A thermo-hygrograph or hygrothermograph is a chart recorder that measures and records both temperature and humidity (or dew point).Similar devices that record only one parameter are a thermograph for temperature and hygrograph for humidity.

  6. Thermodynamic diagrams - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_diagrams

    The path or series of states through which a system passes from an initial equilibrium state to a final equilibrium state [1] and can be viewed graphically on a pressure-volume (P-V), pressure-temperature (P-T), and temperature-entropy (T-s) diagrams. [2] There are an infinite number of possible paths from an initial point to an end point in a ...

  7. ASHRAE 55 - Wikipedia

    en.wikipedia.org/wiki/ASHRAE_55

    It is based on the Predicted Mean Vote (PMV) model. [4] The graphic comfort zone model is limited in applicability to conditions when the metabolic rate of occupants is 1.0-1.3 met and the humidity ratio is below 0.012 kg H 2 O/kg dry air (0.012 lb H 2 O/lb dry air). If these requirements are met and the environmental conditions inside the ...

  8. Insulation system - Wikipedia

    en.wikipedia.org/wiki/Insulation_system

    Insulation does not suddenly fail if the hot-spot temperature is reached, but useful operating life declines rapidly; a rule of thumb is a halving of life for every 10 °C temperature increase. Older editions of standards listed materials to be used for the various temperature classes.

  9. Relative permittivity - Wikipedia

    en.wikipedia.org/wiki/Relative_permittivity

    Sensors can be constructed to detect changes in capacitance caused by changes in the relative permittivity. Most of this change is due to effects of temperature and humidity as the barometric pressure is fairly stable. Using the capacitance change, along with the measured temperature, the relative humidity can be obtained using engineering ...
