Abstract

The invention relates to the field of heat exchange, namely, to the systems for heating/warming of premises with several heat exchange contours and common system of heat carrier distribution and control. The technical result is increase of temperature regularity of heat carrier distributed from the pressure header into the separate heat exchange contours. The essence of the invention is that the heating-mixing device of a liquid heating system contains the distributive pressure and return headers, having the input end and the output end, as well as side offsets located along the headers, the circulatory pump, the intake nozzle of which is connected with the return header, and the delivery one—is connected with the pressure header. The headers are connected together by means of the bypass nozzle. At that the device is equipped with the block of electrical control, and on the input end of each header the temperature sensor and the thermostat are sequentially installed, being electrically connected to the control block, at that the inlet in each header is connected to the source of warmed heat carrier. According to the invention, the intake nozzle of the pump is connected with the output end of the return header, and the delivery nozzle is connected with the input end of the pressure header. The bypass nozzle connects the output end of the pressure header and the input end of the return header, at that the return header is located along the pressure one, and the input end of one header is located opposite the output end of another header.
