The main goal of this thesis document is to facilitate the investigation of cooling water usage in Instrument and Control Facility laboratory. This thesis report illustrates the main idea on how the investigation of cooling water usage was conducted.

The problem arising from the Instrument Control Engineering, ICE lab is pointed out in this study, and it is expected that this study could solve the problem, hence benefit the School of Engineering and Energy. In this document the usage of cooling water will be investigated and examined as possible cold water is supplied to the testing equipment such as the heat exchanger. In this thesis, the control methodology that was applied to investigate the best solution to control the process was described and new arrangement to setup the stand-alone refrigerator in ICE lab was conducted and outlined in this report. The tasks on this thesis has been sorted out and divided into seven sections to ensure that it flows accordingly towards favourable outcome.

This thesis objective is broken down into three categories, which are Instrument investigation, commissioning the cold water from refrigerator with target operating temperature at ≈15⁰C ± 2⁰C, and development and implementation of control loop. In instrument investigation phase, the literature review on most of the equipment has been conducted. The focus was more on operating the refrigerator to produce cold water to the process investigation unit. Following the second phase, the aim was to conduct and design the layout of the process structure. Starting from the hardware arrangement followed by the software development. The last objective is implementation and commissioning the process investigation upon the testing module instrument. Despite that, the designing and tuning controller of the process was discussed in this final objective. Hence, the result or response from the process variable has been analysed and compared for the best performance criteria.

The further direction of this thesis was explained at the end of the document. The new program of the controller has been developed using Laboratory Virtual Instrumentation Engineering Workbench, LabView programming. The outcome from the control programming shows that the offset occurred and this program requires further modification in order to ensure that the program is more reliable and useful to apply the advanced control scheme. Overall, this thesis objective was achieved, whereby the new cooling usage could be used with limitation cold water supply. Thus, it will open a future work to be done on the hardware setup to supply completed cooling water usage in the Instrument and Control Facility laboratory.
