ترجمة الملخص

The control panel for the chilled water machine (chiller) located in the Studies and Researches Center in Misyaf has been inoperable for some time and there is no possibility of repair because the manufacturer did not disclose all its components to the monopoly and because of the economic sanctions and the large costs of replacing the control panel through the black market, so it was necessary to design a new control system .In this research ,a design of a monitoring and controlling circuit for an air cooled chilled water machine has been made, replacing an old expensive electronic control panel, so that the new control circuit covers all control functions of the old panel with better efficiency and less cost.In the beginning, a theoretical study of the mechanism of the chiller and its cooling cycle and the characterization of its main and secondary components was given, in addition to the controlled components that are included in the control system and their working mechanism. The old control system and the control functions that the new system should be covered were described. A detailed explanation of the software and the programming environment used in the new system (LabVIEW program, Automation Studio program, the software environment of the Arduino, the environment of the temperature controller) was made. Then, we designed a new control system using a temperature controller and a set of electric driving elements. A simulation of the driving circuit was carried out using Automation Studio. The elements and equipment needed to build the circuit were then selected, described and studied. The functions and protections provided by this circuit were presented. The steps of designing the computer monitoring system by using Arduino and the steps of the connection with the computer and the design of the program and how to model the equation (Stenhart and Hart) for the temperature sensor ntc and how to display and correct the temperature within LabVIEW environment were explained .The application interface built within (LABVIEW) environment and connected with (Arduino MEGA) allows to view the working condition of the chiller, fault cases and water temperature at the inlet and outlet of the machine in the form of graphic curves and numerical values. The last part of the research discusses the test results of the monitoring and controlling system that we designed and implemented as it provides complete protection from electrical and mechanical faults, easy maintenance, flexibility of temperature control, reading and calibration. It also distinguished from the old system by the ability to monitor the chiller locally and remotely at a cost of 15% of the cost of the old system. It should be noted that this research is done by the researcher without the participation of the technicians of the institute
