LabVIEW Application for Data Acquisition System of Ejector Refrigerator

Abstract:

Article Preview

In order to analyze the performance of ejector refrigerator, it is necessary to collect the operation parameters of the system. In this paper, the development of data acquisition(DAQ) system for ejector refrigerator is described. It is based on the technique of visual instrument and the characteristic of ejector refrigerator, using National Instrument’s product LabVIEW. The proposed DAQ system consists of a set of sensors for measuring operating parameters of ejector refrigerator. The collected data are first conditioned using Agilent 34970 data acquisition switch unit and then interfaced to a PC using RS232. The LabVIEW program is used to further process, display and store the collected data in the PC disk. It 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 providing users with historic data inquire. The proposed software architecture permits the rapid system development and has the advantage of flexibility and it can be easily altered for application in other refrigeration systems.
