Abstract
Objective. The aim of the work is to determine the effectiveness of an upgraded refrigeration unit using experimental studies on a household refrigerator.
Method. During the experimental studies, methods of direct measurement of the main parameters of a household refrigerator were used, as well as a comparative analysis of the indicators of an upgraded refrigerator with those of the basic model.
Result. Experimental studies of a household refrigerator have been conducted. The study used the most popular refrigerants in household refrigerators: R134a and R600a. Based on the conducted research, comparative diagrams of the indicators of the coefficient of working time of the refrigeration unit, the power consumption of the electric motor of the compressor and the consumption of electric energy of the refrigerator are constructed.
Conclusion. The test results of the upgraded refrigerator show that the developed scheme of the refrigerating unit of a household two-chamber refrigerator allows to reduce daily energy consumption by an average of 6-7%.
