"R-134a hydrofluorocarbon largely replacse freon, while not breaking down Earth's ozone layer, is greenhouse gas... replacement with plastic organic ionic crystals, whose moleculest when pressurized move from disorganized to neat grid, absorbing heat/ chilling surrounding air... when pressure released returns to disorganized... pulls heat from air ranging from -37 to 10°C... compression chamber repeatedly squeezes/ un-squeezes crystals, added fan blows chilled air into area around device... future: less pressure/ cost"
