Abstract (en)
The invention relates to a rotor assembly and a heat/energy recovery unit having a rotor assembly in which inlet air (I) is heated to supply air (S) by using thermal energy of discharge air (D) such that the discharge air (D) is cooled to outlet air (O). The heat/energy recovery unit having a rotor assembly comprises: a rotor (1), an inlet plenum (14) for conducting inlet air (I) to the rotor (1), a supply plenum (15) for receiving supply air (S) from the rotor (1), a discharge plenum (16) for conducting discharge air (D) to the rotor (1), an outlet plenum (17) for receiving outlet air (O) from the rotor (1), a circumferential sealing unit (2, 6), a first axial sealing unit (4, 7), and a second axial sealing unit (5, 10). The sealing units (2, 6; 4, 7; 5, 10) are provided with a pressure balancing volume (8, 9) between the plenums (14, 15, 16, 17), said pressure balancing volume (8, 9) allowing an air leakage between the opposing plenums (14, 15); (16, 17), through the side surfaces (24), (25) of the rotor (1).
