VENTILATION SYSTEM FOR LIVESTOCK BUILDINGS Russian patent published in 2023 - IPC F24F7/06 

FIELD: ventilation.

SUBSTANCE: invention relates to ventilation of livestock premises, in particular to ventilation with forced air circulation. The task to be solved by the ventilation system of livestock buildings includes improving the energy efficiency of the system and the quality of the microclimate by removing excess hazards from the serviced premises, in particular moisture and ammonia, ensuring the standard parameters of the microclimate by introducing a heat pump unit into the system, which allows heating the air in a cold period and cooling it in a warm period in accordance with the requirements of the sanitary standards of livestock enterprises. The ventilation system includes exhaust and supply air ducts installed in each other with a gap and forming a heat exchange device. In the proposed solution, the heat exchange device is installed vertically, the exhaust duct is coaxially placed inside the supply air duct, in the lower part the exhaust duct is equipped with a condensate trap, and in the upper part it is connected to the fan, whereas the inlet tangential branch pipe of the exhaust duct is connected to the exhaust hood, and the supply air duct has an inlet and outlet branch pipes, and the inlet pipe is connected to the supply device, and the outlet pipe is connected to the heat pump through its condenser unit, in turn, connected to the air distributors 22.

EFFECT: improved ventilation efficiency.
