FIELD: power engineering.
SUBSTANCE: invention relates to a climatic supply and exhaust unit with a heat exchanger and is intended primarily for servicing buildings of the agro-industrial and/or livestock sectors. The ventilation unit comprises a housing with a heat exchanger located in it, including tubular elements, exhaust and supply fans and a supply air heating device configured to automatically control the air temperature, between the heat exchanger and the supply air heating device a recirculation check valve is installed in the housing wall for additional supply of exhaust air, whereas inside the housing there is a device for cleaning the tubular elements of the recuperator.
EFFECT: invention makes it possible to increase efficiency and reduce energy consumption when operating the unit with lamellas resistant to aggressive environments both in winter and summer periods, and the lamella cleaning device, in addition, will allow to extend the life of the unit.
