Performance Evaluation and Continuous Monitoring of Ice Plant with R134a Refrigerant by Using NI LabVIEWTM DAQs of System

The paper aims at study of performance evaluation and its continuous monitoring with auto control system. This Ice plant works on the principle of Vapour compression cycle using eco-friendly refrigerant R134a. The refrigerant R134a is used as it is best alternative to R12, have zero Ozone Depletion Potential (ODP) and have similar thermodynamic properties to R12. Performance of Ice plant is very much sensitive with operating parameters so that continuous monitoring is very much needed with the provision of data backup. NI LabVIEWTM DAQs is used for real-time monitoring of the Ice plant setup. The DAQs can realize the real-time data acquisition of temperature, pressure as well as data processing and display, in addition to provide users with historic data and alarms regarding operation of the Ice plant system. NI module creates an interface between temperature sensor and computer. The computer Program calculates the refrigerating effect produced and different COP of setup using property table of refrigerant fed in it. It saves a lot of manual operation and also made measurement more convenient and fast
