    A ton of refrigeration is approximately equal to the cooling power of one short ton (2000 pounds or 907 kilograms) of ice melting in a 24-hour periodRetrieved 2010-08-09Archived from the original on 2015-06-10^ "PTAC Buying Guide"Science and Civilisation in China, Volume 4: Physics and Physical Technology, Part 2, Mechanical EngineeringAir conditioning can also be provided by a process called free cooling which uses pumps to circulate a coolant (typically water or a glycol mix) from a cold source, which in turn acts as a heat sink for the energy that is removed from the cooled spaceIn 1820, English scientist and inventor Michael Faraday discovered that compressing and liquefying ammonia could chill air when the liquefied ammonia was allowed to evaporate^ "Air Conditioners & Dehumidifiers"PTACs, which are frequently used in hotels, have two separate units (terminal packages), the evaporative unit on the interior and the condensing unit on the exterior, with an opening passing through the wall and connecting themWhen they are released accidentally or deliberately, these chlorine-bearing refrigerants eventually reach the upper atmosphere.[55] Once the refrigerant reaches the stratosphere, UV radiation from the Sun homolytically cleaves the chlorine-carbon bond, yielding a chlorine radicalRetrieved 2015-06-10

     

    Since many animals normally reproduce only in spring, holding them in rooms in which conditions mirror those of spring all year can cause them to reproduce year-roundProcess applications include these:An example of an externally fitted AC unit which uses a heat pump systemThe evaporation of water cooled the air blowing through the windowRetrieved 2015-06-10Retrieved 2017-04-17Inverter type Air Conditioners use the inside coil temperature sensor (typically used for heat pump operation where it regulates fan speed according to how warm the evaporator is) to adjust compressor speed to keep the evaporator as cold as possible, when the evaporator is too cold[clarification needed] the compressor is slowed or stopped with the indoor fan runningOther techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season.[4]finally decide in favor of the ozone- and climate-safe refrigerant for U.S500 W 1000 h = 500,000 Wh = 500 kWh ^ Jan FInstallation types[edit]Evaporative coolers, sometimes called "swamp coolers", do not have a compressor or condenser^ "Impact of Vehicle Air-Conditioning on Fuel Economy" (PDF)doi:10.1038/NCLIMATE2741^ "2010 to 2015 government policy: environmental quality" 87c6bb4a5b
