  2. Dehumidifier - Wikipedia

    en.wikipedia.org/wiki/Dehumidifier

    A typical "portable" dehumidifier can be moved about on built-in casters. A dehumidifier is an air conditioning device which reduces and maintains the level of humidity in the air. [1] This is done usually for health or thermal comfort reasons or to eliminate musty odor and to prevent the growth of mildew by extracting water from the air. It ...

  3. Atmospheric water generator - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_water_generator

    State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.

  4. Heating, ventilation, and air conditioning - Wikipedia

    en.wikipedia.org/wiki/Heating,_ventilation,_and...

    A dehumidifier is an air-conditioner-like device that controls the humidity of a room or building. It is often employed in basements that have a higher relative humidity because of their lower temperature (and propensity for damp floors and walls).

  5. 2021 Texas power crisis - Wikipedia

    en.wikipedia.org/wiki/2021_Texas_power_crisis

    On February 16, 2021, Governor Greg Abbott declared that ERCOT reform is an emergency priority for the state legislature, and there would be an investigation of the power outage to determine long-term solutions. [124] The legislature held hearings with power plant chief executives, but not with natural gas industry leaders. [22]

  6. Nurse scheduling problem - Wikipedia

    en.wikipedia.org/wiki/Nurse_scheduling_problem

    Solutions to the nurse scheduling problem can be applied to constrained scheduling problems in other fields. [2] [3] While research on computer-assisted employee scheduling goes back to the 1950s, [4] the nurse scheduling problem in its current form was introduced in two parallel publications in 1976. [5] [6] It is known to have NP-hard ...

  7. Humidity - Wikipedia

    en.wikipedia.org/wiki/Humidity

    Solutions for energy-efficient buildings that avoid condensation are a current topic of architecture. For climate control in buildings using HVAC systems, the key is to maintain the relative humidity at a comfortable range—low enough to be comfortable but high enough to avoid problems associated with very dry air.

  8. Air ioniser - Wikipedia

    en.wikipedia.org/wiki/Air_ioniser

    Usually, the work is done over a special dissipative table mat, which allows a very slow discharge, and under the air gush of an ioniser. The ionization falls off very sharply with distance (even in ducting), so air ionization is rarely used for this purpose, and only for items immediately adjacent to the actual ionizer.

  9. Humidor - Wikipedia

    en.wikipedia.org/wiki/Humidor

    This phenomenon was so great that in order to put an end to much controversy, in 2002, nine years after joining the league, the Colorado Rockies started storing their game balls in a large walk-in humidor at their home stadium, [2] thus counteracting the effects of the low humidity due mainly to Denver's famous mile-high altitude of around ...
