Design of air-cooled chiller performance test system based on GPIB interface

The air-cooled chiller performance test software was developed according to the air-cooled chiller performance test requirements of GB/T 18430.1-2007 and AHRI 551/591.It is special software for collecting,monitoring and handling the parameter in the process of testing the rated performance of the 500RT air-cooled chiller.The test software was developed based on the most commonly used programming language Visual Basic and programmed to save and analyze the data collected in the performance test process automatically and transfer the data acquired by several data acquisition instruments to computer by means of GPIB interface communication.Acquisition and monitoring for the parameters of air-cooled chiller during performance testing process could be realized at different work condition,also the most important functions,such as determining the steady status of test system automatically,valid data storage and report output are provided for the acquisition software.
