© 2023Designing refrigerated display cabinet with a high coefficient of performance and low energy consumption have a crucial role to maximize energy savings. Compressors have a leading position in refrigeration systems which use mechanical vapor compression in terms of energy consumption. Proper selection and adaptation of compressors will increase the efficiency of the refrigeration system and reduce energy consumption to a large extent. In this study, an eco-friendly refrigerated display cabinet with variable speed compressor technology was designed to analyze the effects of fixed and variable speed compressor technologies on the coefficient of performance and total energy consumption. Two identical refrigerated display cabinets which had different compressor technologies were tested in Class 3 (25 °C, Rh 60 %) conditions in accordance with ISO 23953-2: 2015 standard. Environmentally friendly R290 (Propane) was used as a refrigerant in both systems. During the experiment, 11.2 kWh/24 h total electrical energy was consumed per day in the system with fixed speed compressor (System 1) and 8.3 kWh/24 h total electrical energy per day in the system with variable speed compressor (System 2). In order to contribute to the widespread use of environmentally friendly cabinets, it was observed that System 2 consumed 25.9 % less energy than System 1 with the help of a variable speed compressor.
