METHOD OF AUTOMATIC HEAT CONSUMPTION CONTROL OF BUILDING IN A CENTRAL HEAT SUPPLY SYSTEM Russian patent published in 2016 - IPC F24D19/10 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering and can be used for weather-dependent regulation of the heat flow in central heating systems of buildings and structures. In method of controlling operating mode of heating system, which comprises periodic supply of heat carrier in building heating system in form of a pulse whose duration is shorter than or equal to a preliminarily set period of heat carrier flow rate control, in measurement of heat carrier temperature in return line of building heating system and in measurement of ambient air temperature, as well as in correction of pulse duration of heat carrier, circulation pump is placed in the jumper between the supply line and return line, the specified value of heat carrier temperature in return line functionally associated with temperature of ambient air, is introduced the minimum step and set to it the multiple step change of pulse duration of heat carrier in each period of heat carrier flow rate control, the sign of step change of pulse duration depends on the ratio of the specified value of heat carrier temperature in return line and heat carrier temperature in return line, and also appoint a step change of heat carrier temperature in return line for the period of heat carrier flow control at minimum value of pulse duration of heat carrier, equal to minimum step of change of pulse duration of heat carrier in the period of heat carrier flow rate control, while at the beginning of each period of heat carrier flow rate control are compared to the specified value of heat carrier temperature in return line with heat carrier temperature in return line, determined rounded value of frequency correction step change of pulse duration of heat carrier in the i-th period of heat carrier flow rate control and corrected value of pulse duration in the i-th period of heat carrier flow rate control, and during pause in each period upon termination of the supply of heat carrier in the building heating system include a circulation pump, provide forced circulation of heat carrier in the building heating system and align the heat carrier temperature in return pipelines of building heating system.

EFFECT: higher reliability, efficiency and accuracy of heat consumption control of building included in the system of the central heat supply system.
