Abstract

In a regenerative heat exchanger with a rotating rotor having radially and axially sealed-off storage masses, a high degree of tightness is achieved and leakages are largely avoided if the housing (12) surrounding the rotor (3) axially and the separating zones (14) arranged radially between the heat-exchanging media are designed as blocking chambers (circumferential or radial chambers 13, 13a, 13b or 15). Such a regenerative heat exchanger allows an operating mode such that sucking off, blocking, blowing out or sucking in can take place at respective tight points in a controlled and appropriate manner in accordance with the pressure conditions prevailing locally in the heat exchanger. <IMAGE>
