VENTILATION AND HEATING UNIT WITH THERMOELECTRIC HEAT PUMP Russian patent published in 2022 - IPC F24F3/00 F24F12/00 F24F7/08 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely to electrothermal energy-saving devices designed to create the required microclimate parameters in the premises of livestock farms. SUBSTANCE: ventilation and heating unit with thermoelectric heat pump contains fans of supply and exhaust air, heat exchanger made of polymeric materials, supply air branch pipe, exhaust and supply air ducts, air purification filters, supply air distributor, corona discharge ozonizer with ozone supply pipelines, recirculation channel. The ventilation and heating unit is equipped with a thermoelectric heat pump, including a cold circuit heat exchanger, a cold circuit pump, a cold circuit pipeline, a Peltier element cold side radiator, a Peltier element power source, Peltier elements, a Peltier element hot side radiator, a hot circuit pump, a hot circuit pipeline, hot circuit heat exchanger. At the same time, the thermoelectric heat pump takes part of the heat from the air removed from the room in the cold circuit heat exchanger and transfers it from the cold circuit to the hot circuit, while the supply air is heated in the hot circuit heat exchanger, and the cold circuit heat exchanger is installed in the exhaust air duct and connected by the cold circuit pipeline with a radiator of the cold side of the Peltier elements, forming a closed cold circuit, through which a coolant circulates with the help of a cold circuit pump, and the hot circuit heat exchanger is installed in the supply air inlet and is connected by a hot circuit pipeline to the hot side radiator of the Peltier elements, forming a closed hot circuit, through which the coolant circulates with the help of a hot circuit pump.

EFFECT: reduction of energy consumption for heating supply ventilation air during the heating period of the year.
