METHOD OF AUTOMATIC CONTROL OF COMBINED HEAT LOAD

FIELD: heat power engineering. ^ SUBSTANCE: invention relates to heat power engineering end it can be used in open heat supply systems of residential, public and industrial buildings at dependent connection to heat network. Proposed method of automatic control of combined heat load of heat points of open heat supply system with dependent connection of risers of circulation circuit of hot water supply system, heating ventilation and water-to-water elevator of heating system equipped mainly with commercial heat energy metering unit provides maintaining of normal water temperature for hot water supply and required air temperature in heated rooms defined by actual operating conditions of centralized heat supply system within limited values. Amount of heat getting into heating system and water dispensing risers of hot water supply is changed depending on absolute current temperature of ambient air, and heating schedule at output of heat supply system at noncontrolled increase of not water consumption for domestic needs and changing load in heating ventilation is executed as close as possible. Device for automatic control of combined heat load is described in invention. Invention provides, within the limits of heat accumulating capacity of barriers of heated building, a closed cycle of compensation of heat losses at changes of ambient air temperature without waiting for changes of thermal conditions of operation of heat supply system and increased efficiency of control owing to maintaining constant summary flow rate of heat carrier in heat supply system which provides designed (when necessary, required) heat consumption of object and reduction of flow rate of high temperature heat carrier up to 20-30%. ^ EFFECT: reduced consumption of high temperature heat carrier. ^ 4 cl, 2 dwg
