METHOD OF HEAT SUPPLY Russian patent published in 2007 - IPC F24D3/02 

FIELD: heat power engineering.

SUBSTANCE: method comprises supplying heat-transfer agent to a heater made of a vortex pipe and branching the heat-transfer agent flow into cold and hot flows. The hot flow of heat-transfer agent is supplied to the consumed and is returned through the piping unit to the heating unit. The cold flow of heat-transfer agent is supplied to the heat exchanger where it is heated by means of a source of external heat and is supplied to the units for mixing it with the hot flow of the heat-transfer agent. The amount of heat supplied to the heat exchanger from the external source is controlled in order to keep constant the temperature of the heat-transfer agent discharging from the mixing unit. The temperature of the cold heat-transfer agent flow is controlled at the entrance to the heat exchanger. The temperature of the mixed flow of the heat-transfer agent is controlled downstream of the mixing unit.

EFFECT: enhanced efficiency.
