FIELD: agriculture.
SUBSTANCE: invention relates to the field of agriculture, namely, equipment for creating a microclimate in rooms for agricultural purposes. Air-thermal curtain comprising air distributor with air ducts, heater, electric fan and control unit, is equipped with compact thermoelectric heat pump consisting of thermoelectric module 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 via hot circuit via hot circulation pump to air heater and return pipeline of hot circuit with heat exchanger of hot junction, forming closed hot circuit for heat carrier circulation. Other side of the thermoelectric module cools the heat carrier, which by means of the circulation pump via the cold loop pipeline enters the cold loop heat exchanger installed in the barn exhaust air duct, where it is heated with warm removed air from the cowshed and, via the cold pipeline return pipeline, enters the intermediate heat exchanger located in the boiler where it is cooled with tap water from the water supply network for animal drinking. From the intermediate heat exchanger, the coolant passes through the cold circuit to the cold junction heat exchanger to form a closed loop. Tap water heated in boiler is supplied for animals drinking to drinkers.
EFFECT: higher reliability and economy.
