Abstract:
Usage of the actual analogue-digital systems allows the elaboration of news principles and methods for measurement (or improving the
existing ones) for obtaining some excellence performing (high precisions, low dimensions). In this study the implementation of two such
systems of measurement, which use two different methods from analogue-digital converting, for experimental study of behaviour to
transfer of a heat exchanger, „pipe-in-pipe” type is presents. Using the mathematical analysis program MATLAB 6.5 and STATISTICA
6.0 for processing the experimental data, the correspondent mathematical models have been deduced.
