OPTIMIZATION OF VARIOUS PARAMETERS FOR ENHANCING THE PERFORMANCE OF MULTI-COMPRESSOR REFRIGERATION SYSTEM

Abstract

The present optimization has been done on multi-screw compressor system. Refrigeration cycle requires a lot of improvements for better performance to fulfill the desired condition with high performance in multi-compression system. Many of the parts run during the cooling effect and the running condition of system may vary as per the condition like ambient condition, part load, full load etc has also been changing which create an effect on the suction pressure, evaporator temperature, the rate of heat exchange, refrigerant flow and many other factors which are continuously changing. For efficient cooling process, the noise parameter of the system has to be analyze and its affecting level for the designed system. These noise parameter has controlled (minimize) by some controlled parameter. In this project, the optimization parameter is the Power and the affecting parameters are temperature, discharge pressure and slide valve positioning. The variation in these parameter with different working condition has analyze. The deviation in the effective cooling process can be obtained by its optimization. For the optimization process, taguchi approach with four factor and three level has selected which is best suitable with these conditions. This approach provides the best suited result for the different working conditions as per the requirement of the company. So the main motive of this work is to analyze the noise parameter and provide the best suited parameters in different working conditions so that effective and efficient cooling may be provided for the organization.
