ROOM AIR TEMPERATURE CONTROL DEVICE

FIELD: power industry. ^ SUBSTANCE: air temperature control device of the room heated with open heat supply system includes circuits of common circulation and recirculation with straight and return main lines, each of which is equipped with circulation pump with actuator and rotation speed control, which is connected respectively at pump of recirculation circuit to pressure control output, and at pump of common circulation to air temperature control output, which also includes temperature sensor on return main line at heating system outlet; at that, at outlet of circulation pump of straight main line of common circulation circuit there located is heat counter, and at circulation pump outlet of recirculation circuit there arranged is heat carrier flow counter. Air temperature control is connected to temperature sensor made in the form of differential thermocouple the sensitive elements of which are located respectively in the room and out of the room heated with open heat supply system. Besides, pressure control is connected to pressure sensor of circulation circuits of rooms of the heated room, which are different as to temperature modes. Each of pressure sensors is installed on return main line of heating system; besides, each of rotation speed controls is made in the form of unit of powder electromagnetic couplings. Temperature control and pressure control include comparing unit and assignment unit respectively; besides, comparing unit is connected to output of electronic amplifier equipped with non-linear feedback unit. Output of electronic amplifier is connected to input of magnetic amplifier with rectifier, which is connected at the output to speed control in the form of powder electromagnetic couplings unit. ^ EFFECT: reducing power consumption of supplied heat at maintaining the specified temperature in rooms with various comfort levels for conditions of varying ambient temperature within a day and at longer time intervals. ^ 1 dwg Изобретение относится к области автоматического регулирования и управления, в частности к устройствам для регулирования температуры воздуха в помещениях, отапливаемых от систем открытого теплоснабжения.
