How a clothes dryer removes moisture from the load and disposes of it: a vented dryer expels warm humid air through a duct to outside; a condenser dryer cools the moist air to collect water in a reservoir (or drain); a heat-pump dryer recirculates low-temperature air through a refrigerant heat exchanger for much higher efficiency; a gas dryer burns gas to heat the air. A token category recurring across products (L11); growing (L13).
