MODIFICATION OF REFRIGERATION SET IN MECHANICAL ENGINEERING TECHNOLOGY DEPARTMENT
Abstract
ABSTRACT
This project focuses on the modification and maintenance of a domestic refrigeration set in the Mechanical Engineering Technology Department. The aim was to evaluate the existing system, identify inefficiencies, and improve its performance, reliability, and energy efficiency. Key components, including the compressor, condenser, evaporator, capillary tube, and stabilizer, were selected and modified according to manufacturer specifications and standard refrigeration design principles. The project involved cleaning, leakage testing, system evacuation, refrigerant charging with eco-friendly R600A, and installation of a vibration damper to reduce noise and mechanical stress. Performance testing demonstrated significant improvements: cooling time was reduced by 44%, power consumption decreased by approximately 36%, and suction and discharge pressures stabilized within recommended ranges. The modifications also enhanced the mechanical stability, operational safety, and aesthetic finish of the unit. Overall, the project successfully upgraded the refrigeration system, providing a reliable, energy-efficient appliance suitable for practical training and demonstration purposes.
