  2. Evaporative cooler - Wikipedia

    en.wikipedia.org/wiki/Evaporative_cooler

    The evaporation rate depends on the temperature and humidity of the air, which is why sweat accumulates more on humid days, as it does not evaporate fast enough. Vapor-compression refrigeration uses evaporative cooling, but the evaporated vapor is within a sealed system, and is then compressed ready to evaporate again, using energy to do so. A ...

  3. Evaporation - Wikipedia

    en.wikipedia.org/wiki/Evaporation

    Evaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water. In hydrology, evaporation and transpiration (which involves evaporation within plant stomata) are collectively termed evapotranspiration. Evaporation of water occurs when ...

  4. Wet-bulb temperature - Wikipedia

    en.wikipedia.org/wiki/Wet-bulb_temperature

    The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.

  5. Find out why your fridge isn’t working but your freezer is still cold with this guide. Learn how to check for issues with the thermistor, evaporator coils, and more.

  6. Vapor-compression evaporation - Wikipedia

    en.wikipedia.org/wiki/Vapor-compression_evaporation

    Vapor-compression evaporation is the evaporation method by which a blower, compressor or jet ejector is used to compress, and thus, increase the pressure of the vapor produced.

  7. Joule–Thomson effect - Wikipedia

    en.wikipedia.org/wiki/Joule–Thomson_effect

    The gas-cooling throttling process is commonly exploited in refrigeration processes such as liquefiers in air separation industrial process. [ 7 ] [ 8 ] In hydraulics, the warming effect from Joule–Thomson throttling can be used to find internally leaking valves as these will produce heat which can be detected by thermocouple or thermal ...

  8. Evaporator - Wikipedia

    en.wikipedia.org/wiki/Evaporator

    Because the cooling water, which is chemically treated fresh water, is at a temperature of 70–80 °C (158–176 °F), it would not be possible to flash off any water vapor unless the pressure in the heat exchanger vessel is dropped. A brine-air ejector venturi pump is then used to create a vacuum inside the vessel, achieving partial evaporation.

  9. Vacuum evaporation - Wikipedia

    en.wikipedia.org/wiki/Vacuum_evaporation

    The vacuum evaporation treatment process consists of reducing the interior pressure of the evaporation chamber below atmospheric pressure. This reduces the boiling point of the liquid to be evaporated, thereby reducing or eliminating the need for heat in both the boiling and condensation processes.
