Abstract

Energy efficiency efforts and proper temperature control in domestic cooling systems are important in the world of domestic refrigeration. This can be done in several ways, such as changing the refrigerant used or replacing the expansion device currently used. This study investigates the potential benefits of integrating a thermostatic expansion valve (TEV) with the aim of improving energy efficiency, temperature stability and extending system life. From the literature review that has been carried out, TEV offers significant advantages over installed capillary pipe systems, including improved refrigerant flow regulation, optimal evaporator performance, and good temperature management. Additionally, TEV facilitates adaptive control mechanisms, allowing the refrigerator to adjust operation based on varying load conditions, ambient temperature and user preferences which has a significant impact on reducing energy consumption, minimizing temperature fluctuations and extending compressor life. This research will be carried out using an experimental method by comparing the work of the two expansion devices. By analyzing data collected from experiments and calculations in the coefficient of performance (COP) software, the performance and electrical energy efficiency of the two expansion devices can be identified and compared so that it can offer practical guidance for refrigerator manufacturers and designers.
