AIR CURTAIN WITH THERMOELECTRIC HEAT PUMP IN MILKING UNIT OF CATTLE FARM Russian patent published in 2020 - IPC F24F9/00 A01J9/04 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, namely, equipment for creating a microclimate in rooms for agricultural purposes. Air curtain with thermoelectric heat pump in milking unit of cattle farm is equipped with compact thermoelectric heat pump consisting of thermoelectric modules with heat exchangers of hot and cold junctions, when connecting the thermoelectric module to the control unit, one side of the module emits heat which is transmitted to the heat carrier, wherein hot junction heat exchanger is connected by hot circuit via hot circuit circulation pump to air heater and return pipeline of hot circuit with hot junction heat exchanger, forming closed circulation circuit for hot heat carrier circulation, and other side of thermoelectric module is cooled and takes heat from heat carrier by means of cold junction heat exchanger, wherein the heat released from the milk contained in the milk cooler is absorbed by the cold circuit heat exchanger installed inside the cooler, connected by the cold circuit pipeline and the cold circuit return pipeline with the cold junction heat exchanger and through the cold circuit circulation pump with the cold circuit heat exchanger, forming a closed circuit for the cold heat carrier circulation.

EFFECT: as a result of using the proposed invention, consumed energy is reduced for creation and maintenance of microclimate in the milking unit, and also it is possible to preserve stable parameters of air environment in the room with open gates, as well as perform preliminary cooling of milk due to the fact that the air curtain comprises a compact thermoelectric heat pump and a heat exchanger for cooling milk, installed inside the milk cooler in milking unit of the cattle farm.
