METHOD OF OPERATION OF OPEN HEAT-SUPPLY SYSTEM Russian patent published in 2013 - IPC F24D3/00 

FIELD: power engineering.

SUBSTANCE: method of operation of an open heat supply system, according to which delivery water is prepared at a TPP and along a supply pipeline of a heating system via a heating point is sent into pipelines of heating and hot water supply systems for consumers. Delivery water temperature in a supply pipeline is controlled at the TPP depending on the ambient air temperature according to the schedule of central quality control. Delivery water that returned from consumers along a return pipeline of the heating system is sent to the TPP. The feature of the proposed method consists in the fact that the temperature of the delivery water at the TPP for the whole year is adjusted without lower fracture in the temperature curve, additional heating of the delivery 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. Some delivery water from the reverse pipeline of the heating system is sent into a mixer to the evaporator of the heat pump plant along with travel of the delivery water.

EFFECT: higher efficiency of TPP operation due to lower consumption of fuel at a TPP with control of delivery water temperature without lower fracture of a temperature curve.
