METHOD OF OPERATION OF OPEN HEAT-SUPPLY SYSTEM Russian patent published in 2011 - IPC F24D3/08 

FIELD: power engineering.

SUBSTANCE: method of operation of an open heat-supply system, along which heating water is prepared at a thermal power plant and along a supply pipeline of a heating network via a heating unit is sent to pipelines of the heating systems and hot water supply systems to loads, temperature of heating water in the supply pipeline of the heating network is adjusted at the thermal power plant depending on ambient air temperature according to the schedule of central quality control, the heating water that returned from the loads is sent along the return pipeline of the heating network to the thermal power plant. The temperature of the heating water at the thermal power plant for the whole year is adjusted without lower fracture in the temperature curve, additional heating of the heating water sent for hot water supply to the required temperature is carried out in a heat pump plant, a condenser of which is connected to the hot water supply system pipeline by the heated medium, and an evaporator is connected into the return pipeline of the heating network by the heating medium.

EFFECT: increased efficiency of their operation due to reduction of fuel flow to the thermal power plant with adjustment of heating water temperature without lower fracture of temperature curve, more complete usage of heat of return heating water, reduction of heating water temperature in supply and return pipelines of the heating network, increased generation of power for heat consumption.
