Experimental study of the characteristics of an active heat exchanger under changing operating conditions

Annotation

This article presents the results of an experimental study of the active heat exchanger SNAB.065171.001-01 as the main heater of the ventilation system of a real object. The results of determining the specified nominal characteristics of productivity, energy consumption and COP of an active heat exchanger are described. The results of the calculation of empirical coefficients necessary for the calculation of these characteristics in arbitrary operating conditions are presented. The application of the method of technical and economic evaluation of active heat exchangers to determine the characteristics of the device with a change in air flow and operating temperature is demonstrated. The results of calculating the performance characteristics are compared with the results of full-scale experiments to determine the degree of reliability of the proposed methodology.
