FIELD: mechanical engineering.
SUBSTANCE: invention relates to plants making it possible to mix air or liquid medium with simultaneous heating or cooling at provision of increased of power output. Result is obtained owing to the fact that in ventilating and mixing device containing channel for heat or cold carrier, blades, and blade drive, part of heat or cold carrier channel, according to invention, is made in from of heat exchanger functionally coupled with blade drive as with part of said channel.
EFFECT: possibility of heating or cooling of media at increased of power output of device.
