DEVICE FOR AUTOMATED CONTROL OF HEAT CONSUMPTION FOR HEATING IN HEAT SUPPLY SYSTEMS

FIELD: heat supply.SUBSTANCE: invention relates to central heat supply of residential, public and industrial buildings. Device for automated control of heat consumption for heating in heat supply systems includes supply and return pipelines, a bridge connecting supply and return pipelines with mixing pump, a heat flow rate controller for heating with water temperature sensors for heating ambient air temperature, control valve with a drive in the supply pipeline, wherein the heat flow rate controller for heating includes an ambient air temperature recorder and a water temperature logger for heating, which are connected to corresponding temperature sensors, wherein each of the temperature recorders comprises comparison, reference and non-linear feedback units, as well as electronic and magnetic amplifiers, besides, the mixing pump is equipped with a drive with a rotation speed regulator and a control valve with a drive in the supply pipeline equipped with a rotation speed controller in the form of a powder electromagnetic couplings unit, wherein magnetic amplifiers of outdoor air temperature recorder and water temperature logger are electrically connected to corresponding controller of rotation speed of control valve and mixing pump, besides, the inner surface of the connection strap connecting the supply and return pipelines is coated with a nanomaterial in form of a glass-like film, wherein heat carrier quantity regulator located between mixing pump and return pipeline and connected with heat carrier temperature sensor in return pipeline is made on web connecting supply and return pipelines.EFFECT: reduced power consumption for mixing pump drive in conditions of normalized temperature maintenance in heated room due to control of coolant supply from return pipeline at heat carrier temperature recording and accordingly its density in the return pipeline before supply through the mixing pump through the web into the supply pipeline.1 cl, 2 dwg Изобретение относится к централизованному теплоснабжению жилых, общественных и промышленных зданий. Технической задачей предложенного изобретения является снижение энергозатрат на привод насоса смешивания в условиях поддержания нормированного температурного режима в отапливаемом помещении за счет регулирования поступления теплоносителя из обратного трубопровода при регистрации температур теплоносителя и соответственно его плотности в обратном трубопроводе перед подачей через насос смешивания по перемычке в подающий труб
