Yun et al., (2021) conducted an experimental study to evaluate the cooling performance of the battery by using a phase change liquid of R1234yf. It is concluded that both liquids show efficient performance at a temperature below 40 °C. In the case of liquid-to-gas phase change cooling,...
R1234yf/R152abattery thermalmanagementCFDRefrigerant indirect contact phase-change cooling system flows refrigerant\ninto a cold plate and utilizes the phase-change to exchange heat with the\nbattery. However, R134a, commonly used, is being gradually restricted due\nto its environmental impact. A ...
All final solution refrigerants to replace R134a are flammable (both HC's and R1234yf), therefore subjected to refrigerant charge limitations. A series of intermediate GWP not flammable blends were proposed in order to bridge the transition to a later final situation. The most significant ...
(PCMs) are combined with the refrigeration systems, the energy-saving effect is remarkable. The paper reviews the integration of PCMs within CRS, focusing on their potential to reduce energy consumption, thereby improving food safety and reducing reliance on conventional, electricity-intensive ...

Highlights: A novel vapor compression system with phase change material is simulated Performance with R134a, R32, R1234yf, R1234ze (E) and R290 is compared R32 system results in the highest COP with an 8% increase over baseline with R134a R290 system results in the highest charge reduction...
R32 and R125 have lighter molecular weight and higher pressure at\nthe corresponding temperature (0 掳C) than R134a, R1234yf, and R1234ze. Therefore, they are injected more\ninto the compressor. Refrigerants entering the evaporator are decreased. They have a low normal boiling point\n(NBP...
