“…Refrigeration systems used in the field of industrial air conditioning are a closed circuit consisting of compressor, condenser, expansion valve, capillary tube and evaporator elements connected to each other in series [14]. The properties that refrigerants, which are the intermediate that provide heat transfer in the vapor compression refrigeration cycle, are required to have and expected from repair are too many.…”

In this study, the effect of environmentally friendly R290 refrigerant on the performance of the refrigerator was investigated, instead of R404A refrigerant, which negatively affects global warming and is the most frequently used gas in supermarket cabinets. The boundary conditions in the refrigeration cycle were designed to be -10°C evaporation and +45°C condensation, and the performance of the system referenced in the TS EN ISO 23953-2 standard was experimentally compared for both refrigerants. The temperature and energy consumption values of the M-packs, whose location and quantity are specified in the relevant standard, have been evaluated in terms of the cooling performance of the cabinet. As a result of the study, the heat removal performance of the system using R290 fluid in the condenser showed better results compared to R404A. According to the relevant standard, the system using R290 is in the C and D classes in the energy consumption evaluation.

“…In 1996, the production of Chlorofluorocarbon (CFC) type fluids was completely stopped. By 1989, alternative fluids were developed by finding hydrofluorocarbon (HFC) origin R134a and R123 refrigerants that do not harm the ozone layer [5,6]. 2020) evaluated the performance of R463A on the system using R404A.…”

Cascade refrigeration systems are preferred in applications where low temperature cooling is required, such as in some special industrial and laboratory applications. Since, in these systems, the energy consumed by the compressors is less and the compressor outlet temperature is lower. Due to environmental problems, the use of natural refrigerants in cascade refrigeration systems has become to be of great importance. In this study, two cascade systems consisting of R744/R290 (System 1) and R1270/R290 (System 2) natural refrigerant pairs were designed and thermodynamically examined. In the analyzes performed according to different evaporator temperatures, the highest COP value was 3.66 at -20℃ evaporating temperature was obtained in the cascade system consisting of the R1270/R290 refrigerant pair. Moreover, it was considered that there was a 17.95% enhancement in exergy efficiency with the use of R1270 refrigerant in the low temperature cycle. By the rise in the evaporator temperature, energy consumption decreases and as a result, the amount of carbon dioxide emissions reduced was attained.
