FIELD: heat and power engineering, namely heat exchangers with movable intermediate heat transfer agent, possibly used in ventilation systems of residential, industrial rooms. ^ SUBSTANCE: fan-shaped rotor type heat exchanger includes rotor in the form of pack of plates uniformly distributed along circle and secured to shaft of rotor rotating in direction opposite to cooled and also to heated flows overcoming said plates through heat exchange inserts provided in them. At rotation of shaft plates are drawn together by means of restricting members placed in boundary interfaces of flows passing through heat exchanger. Revolution number of shaft is linearly depends upon flow speeds; proportionality coefficient is controlled by means of control unit on base of measured difference of initial and final temperature values of said flows at realizing function for finding maximum difference between said temperature values. ^ EFFECT: improved efficiency of heat exchanger. ^ 6 cl, 3 dwg |
