FIELD: heating. ^ SUBSTANCE: control method of hot-water heating system includes temperature measurement of heat carrier at the output of heating systems and changing of throttling valve positions. Aiming to increase the effectiveness of hot-water heating system functioning on the basis of heat carrier temperature measuring at the output of each heating system there made calculations of this temperature deviations from its average value among the variety of heating systems; the position of throttling valve plate is also measured. If the deviation mark is positive, the throttling valve of the heating system is moved towards increase of carrying capacity, if the deviation mark is negative - towards decrease of carrying capacity. Meanwhile total changes of throttling valve plates' positions are performed with the saving of value constancy of general hydraulic resistance of hot-water heating system and till mean square value of temperature deviations at the output of the variety of heating systems from the average temperature value of this variety is not acceptable. ^ EFFECT: increase of effectiveness and economy of building heating system at the expense of provision of equal heat radiation of all heating units that comprise heat system. ^ 3 cl, 1 dwg |
