Room ventilator with regenerative heat recovery

摘要

The ventilator (1) uses regenerative heat recovery, and has a regenerator (3) and a fan (4) which are fitted into a pipe, which is made preferably from aluminium or a synthetic material (2). It may also have fan equipment with two pipes (2,12), which are installed close to one another in a wall opening. The regenerator may be may be made from a synthetic material or from metal shavings, and the pipe nozzle may partly be able to be rotated or inclined. The direction of rotation of the fan may also be switched over by a timing unit, whose switching cycles may depend on the speed of rotation of the fan.
