METHOD OF OPERATION OF OPEN HEATING MEDIUM SYSTEM

摘要

FIELD: power industry.SUBSTANCE: method of operation of open heat-supply system under which the system water is prepared at TPP and via the supply pipeline of the heat-supply system via the heating station is delivered to the heat and hot water supply system pipelines of the consumers; the system water temperature in the supply pipeline of the heat-supply system is adjusted at TPP depending on ambient temperature as per schedule of central qualitative adjustment without bottom brake of the temperature curve; the system water returned via the return pipeline of the heat-supply system is delivered to TPP; to ensure the required temperature of water delivered for hot water supply the system water is mixed, for this part of the system water from the supply and return pipelines of the heat-supply system is delivered to the mixer, additional heating of the system water supplied for hot water supply to the required temperature is ensured in the heat pump unit with difference that the heat pump evaporator in relation to the heating medium is connected in the supply and return pipelines of the heat-supply system; part of the system water from the return pipeline of the heat-supply system is delivered in the mixer via the condensate cooler.EFFECT: increased economic feasibility of operation of the open heat-supply system, increased operation time of the heating medium unit due to use of heat potential of the system water from the supply pipeline.1 dwg
