RAC-202 | Refrigeration Cycle Demonstration Unit

Refrigeration cycle demonstration unit is a self-contained vapour-compression refrigeration. Speed and power supplied to compressor are displayed on the PC. Hermetically sealed refrigerant exiting the compressor passes through a condenser, receiver, filter, variable area flowmeter, expansion valve and evaporator.    

SCADA (Supervisory, Control and Data Acquisition)

  SCADA system fully instrumented and computer controlled via USB / Ethernet interface / WiFi to record / set process parameters and to perform related thermodynamic calculations. The idea of controlling any process variable and supervise possible anomalies offer great advantages if they are compared to manual procedures or process which lack of such technology. Besides, the experiments are carried out more effectively. The final result reliability is much higher without doubt, therefore the work done by the researcher possess a higher credibility. SCADA applications contain large number of tools which are useful particularly to the research and the studied area such as Analysing Data in detail once the experimental process has concluded, controlling the automatically the experiments or recording the events while the tests are performed.

Data Storage

The data are stored in a data base either in file format supported by third party software. The data can be represented both numeric format or graphic format like their trends and distributions independently the way it is used. As being available for the users anytime allows different tests to be compared and reach conclusion more truthful.

Control Algorithm

The control algorithm codification about the process offers uncountable interesting points compared to manual actions. The parameters can be controlled as in the case of any hardware element programmatically and with total independency of SCADA architecture used. Not only saving time is achieved but it is perfected over the implemented methodology and major exhaustive control for variables which are take part of the experimental process.

Warning and Alarms

Warning and alarms during tests add great value, especially, to avoid industrial machines are damaged, as case of the individual are exposed to hazard situations. They are great benefit too because they allow to monitor the variables status which are subjected without physical presence exits.
