FIELD: agriculture, possibly poultry farming, animal husbandry with use of common convection and local heating by means of infrared heaters. SUBSTANCE: gas IR-burners assembled in group are secured to horizontal suspension with possibility of their vertical motion and they are connected at their inlets in parallel relative to gas main pipeline. Outlets ( for combustion products) of burners are connected in parallel relative to second gas main pipeline whose outlet is connected to three-section heat exchanger for heating flow-through outer air. In first section inlet for flow of exhaust air and combustion products is connected through centrifugal double-suction blower with adjustable damper by means of first suction branch pipe and with second section by means of second suction branch pipe. Flow of intake outer air in first section is separated from that of second section by means of blower. Inlet (for combustion products) of second heat exchange section is connected with second gas main pipeline and its outlet is connected with inlet of second branch pipe of double-suction blower and with third section. In second section flow of intake outer air is separated from third section by means of adjustable damper connected through first inlet of first actuating mechanism with first comparator whose first inlet is connected with setter and whose second inlet is connected with pickup for monitoring carbon dioxide content in agricultural room. Third section is connected with outlet of second section. Third section is separated by means of adjustable damper from second section; outlet of third section is communicated with air medium of poultry breeder. System is designed for organization of local heating in poultry breeder in such a way that to provide changing of heating degree during first 30 - 60 days of poultry growing and in animal husbandry rooms for heating animals. EFFECT: enhanced ecology, lowered cost price of system, reduced load of ventilation due to prevention of exhaust of combustion products of IR-burners into breeding room. 1 dwg, 4 tbl
