Investigation of chlorine-free HFC refrigerants that have the advantages of both HFC and HCFC. Thus, the new study on the mixing of hydrofluorocarbons takes place and new gases are formed such as R507A and R417a. Not all Blends are the solution for replacing existing refrigerant, as the GWP of the blended refrigerant must be lower than that present using the refrigerant. Among the blends, R417a performed the best and had the capacity to replace the current one using R22 applications. R147a consumes less energy than R22 where the experiment was carried out on the same device and under the same operating conditions. Say no to plagiarism.

Binit Kumar Jha carried out the theoretical study between the environmentally friendly refrigerant R600a and the widely used R134a. refrigerant and observed that the discharge pressure of R600 is lower than that of R134a and the refrigerant effect and coefficient of performance are comparatively high for R600a compared to R134a. Adil F. Momin and Manish H. Attal carried out experimental tests on the domestic refrigerator using phase change materials with R290/R600a mixture as refrigerant, while the PCM used is ethylene glycol, coated on the face rear of the evaporator. Adding PCM improves heat transfer and raises evaporation temperatures. Thermal energy stored in the PCM is used during shutdown cycles, contributing to continued operation of the refrigeration. This results in an increase in the coefficient of performance and a decrease in refrigerant cycle time. Research to find a replacement refrigerant R134a has been conducted by several previous researchers. Prayudi and Roswati Nurhasanah also carried out a performance analysis of R600a and R134a refrigerants with subcooling effect using the liquid-suction heat exchangers with cooling load. Cooling load variations are made by opening the valve to different positions. There is no impact on the compressor work due to the cooling load and the compressor work increases with the subcooling effect. Keep in mind: this is just a sample.

Get a Custom Test The higher the subcooling temperature, the greater the subcooling temperature. the temperature drop in the evaporator and R600a gives better results compared to Prayudi Suparmin performed an experimental analysis on the different refrigerants for different degrees of subcooling. He had used the liquid suction heat exchanger for the different degrees of subcooling and said that subcooling of the refrigerant tends to prevent the formation of flash gas at the throttle valve. According to the experiment he showed, the efficiency of LSHE increases with increasing the degree of subcooling. It showed that the mixture of R290 and R600a in a ratio of 50:50 in a refrigeration system has the highest LSHE efficiency compared to other refrigerants.
