Abstract

In order to enhance the coefficient of performance of solar absorption refrigerator and analyse the system performance, it was necessary to collect the operation parameters in the system. This paper put forward to combine the technique of visual instrument and the characteristic of solar absorption refrigerator, using National Instrument’s product LabVIEW, to develop an effective data acquisition(DAQ) system. This DAQ system can realize the real-time data acquisition of temperature, water flow rate and pressure as well as data transmission, processing, and display, in addition to provide users with historic data inquire. It saved a lot of labor power and material resources so that it made measurement more convenient and fast.
