| Abstract: | Based on virtual instrument technology, it designs a testing system of the plate heat exchanger used at laboratory. This system uses Simens 87 - 200 series model to collect various information, carries out the testing process according to relevant national standards. It describes the testing principle and construction of software/hardware, shows its application of damp and thermodynamics test in the plate heat exchanger. The example indicates that the svstem is effective. |
