FIELD: heat power engineering.
SUBSTANCE: invention relates to heat engineering, namely to devices for measuring exergy of heat energy by convective heat exchange. Model can be used in instrumentation for heating systems and enables to account for heat energy exergy. Disclosed is a device for measuring exergy of working medium, comprising an electromagnetic primary flow converter, installed in middle section of pipe, thermal transducers of resistance on supply and return pipelines, heat calculator, input of which is connected to output of electromagnetic primary flow converter. In device additionally installed are thermal resistance transducer, rigidly fixed on bracket, in upper part of which triangular shield is rigidly fixed, exergy computer, first input of which is connected to output of electromagnetic primary flow converter, and second and third inputs are connected to thermal resistance transducers installed on supply and return pipelines, accounting device, first input of which is connected to output of exergy computer, and second input is connected to heat calculator output, before electromagnetic primary flow transducer filter is installed.
EFFECT: improvement of the measurement accuracy.
