METHOD OF TEST OF THERMAL EFFICIENCY OF HEAT-EXCHANGING APPARATUS Russian patent published in 1998 - IPC

FIELD: heat engineering, metallurgy. SUBSTANCE: method of test of thermal efficiency of heat-exchanging apparatuses by values of temperature of heat transfer agents across inlet and outlet of heat-exchanging apparatus consists in simultaneous measurement of difference of values of temperatures of both heat transfer agents across inlet and outlet of heat-exchanging apparatus with the use of differential thermocouples, for instance, in subsequent calculation of thermal efficiency and in its comparison with critical value. Practical usage of proposed method in ship heat- exchanging apparatuses makes it possible to evaluate objectively and sufficiently accurately efficiency of operation of heat-exchanging apparatuses and to determine periodicity of their preventive cleaning and maintenance operations, to enhance efficiency of usage of heat-exchanging apparatuses of various types and assignment, to carry out work for their updating at stage of design and manufacture more skillfully. EFFECT: expanded application field and enhanced authenticity of method. 4 dwg
