Abstract:

Performance tests for heat exchanger, which are important parts in the design of heat exchanger, have great significance on structural optimization and performance evaluation. In the view of traditional heat exchanger performance test system have the characteristics of long test period, little combination, less automation level, and poor reusability,a kind of control and measure system for heat exchanger performance testing,which is based on the industrial control computer and Builder C++ software platform, is introduced. The system realizes the automation operate such as value control and process simulation, the collection,record and analysis of the test data.On the basis of the hardware design of the system, the paper introduces the programming method by using C++ Builder, and finally gives the user interface and simulation results of the heat exchanger.The result shows that this system has a good interface and easy to use with high reliability, which can meet the requirements of performance test for heat exchanger.
