Oct 22, 2024 ¡¤ The main purpose of this study was to investigate the possibilities of using R134a as a working fluid to replace R22 for vapor compression heat pumps.

Nov 21, 2024 ¡¤ The experimental results show that if a system is undercharged to 90 per cent then the effect is small: a 3.5 per cent reduction in cooling capacity.

Jun 15, 2024 ¡¤ Compared with using R134a, R744 systems can save energy consumption by up to 37% in commercial refrigeration units while R290 systems can provide higher ...

Sep 12, 2024 ¡¤ This paper comprehensively reviews those recent studies that focused on the possible replacement of currently in-use refrigerant with a comparatively more ...

Feb 10, 2024 ¡¤ Refrigerant R22 has approximately 55% higher refrigerating capacity and pressure levels in compari- son to R12. The significantly higher dis- charge gas ...

Dec 15, 2023 ¡¤ This work presents an integrated approach for the rational design of low-GWP refrigerant blends, focused on replacing R134a (GWP 1430), and R410A (GWP 2088).

Dec 2, 2024 ¡¤ This study investigates the performance comparison of transitioning from HFC-134a to R-513A. The chillers have been in operation for two years, and cooling ...

Jun 5, 2024 ¡¤ When the cooling mode changes from refrigerant cooling to liquid cooling under 2C charging, the heat transfer coefficient reduces about 73.6%, and the battery ...

Jun 5, 2024 ¡¤ The choice of refrigerant directly affects cooling performance, and research on vehicle air conditioning (AC) systems can indirectly guide the BTM. R1234yf and ...

Oct 25, 2024 ¡¤ The objective of this study was to select/ design & synthesis of suitable adsorbents for the adsorption-based separation of R32, R22, R125, R134a, R143a ...
