FIELD: heating systems.SUBSTANCE: technique for automatic regulation of flow of heat in a heating system for a dual-flow heating system is based on provision of an optimum mode for the heating system through maintaining given ratios of pressure and temperature in direct and reverse network of pipes consisting of first contour with a heat source, main-line pump with output to a heat exchanger, which is connected to the second contour of the heating network with a circulator pump, and heating system with regulated parameters.

Change in the flow of the heat carrier and its regulation is achieved through pumping units with frequency converters, when signals are applied to the microprocessor, from pressure sensors at the pump input and output, as well as from sensors for active power expended by the motor of the pump. Heat input is calculated in the computer using a formula. There is programmed control of the heat input from the source and the resultant pressure in accordance with the program in the microprocessor controller of the first contour, with consideration of ambient temperature and losses in the network. Regulation of flow is done by a frequency converter through changing the frequency of rotation of the pump shaft.

If necessary, the main-line pump of the first contour is shut down for a defined time when the given ratio between pressure and temperature in the network is maintained, for which the heating system operates in the given mode.EFFECT: increased effectiveness and economy in regulation of heat flow in a heating system.3 dwg
