The invention relates to methods for heat supply. A method of heat supply includes process of heating of main heat carrier by heat source, transportation of heated main heat carrier with supply line from heat source to consumers of heat, takeoff of heat from main heat carrier to heat consumers, transportation of cooled main heat carrier with back line to heat source. Heat takeoff from main heat carrier to heat consumers is realized with intermediate heat carrier, first with supply of heat to it from main heat carrier, and then with increase of temperature of intermediate heat carrier in heat pump cycle and discharge of heat from intermediate heat carrier to heat consumers, at that heat to intermediate heat carrier is supplied from main heat carrier in supply or back line. The invention provides increase of power effectiveness of heat supply due to decrease of temperature of main heat carrier and respectively losses of heat with main heat carrier to environment at transportation. |
