Condenser laundry dryer pump

This video is partly about a special purpose pump, but also explains how a very common European unvented tumble dryer works. They're extremely efficient and require no external exhaust vent. The simplicity of the design is stellar, with one main motor for drum rotation and the hot and cold air-path fans. The fans are the centrifugal type, so even when the machine changes drum direction briefly, the fans still push air around. The water extracted from the clothing is pumped up to a pull-out reservoir which can then be poured into a sink. Alternatively, some of these machines can be plumbed directly to a drain. By recycling the hot air in a loop, these machines have high efficiency, and also contribute to heating your home in winter. Unfortunately they also heat your home in summer, which isn't so good. They also do leak a small amount of fine lint which adds to the usual dust issue in homes, but most of the lint is caught in a small lint trap that is cleaned before each cycle. Because we have very high power available at all sockets in a UK home (32A 240V power circuits) we can plug these machines into any socket in the home. It's common to have the laundry equipment in the kitchen, but the dryer could be put in any spare room in the house.
