Oct 22, 2024The 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, 2024The 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, 2024Compared 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, 2024This paper comprehensively reviews those recent studies that focused on the possible replacement of currently in-use refrigerant with a comparatively more ...
Feb 10, 2024Refrigerant R22 has approximately 55% higher refrigerating capacity and pressure levels in compari- son to R12. The significantly higher dis- charge gas ...
Dec 15, 2023This 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, 2024This 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, 2024When 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, 2024The choice of refrigerant directly affects cooling performance, and research on vehicle air conditioning (AC) systems can indirectly guide the BTM. R1234yf and ...
Oct 25, 2024The objective of this study was to select/ design & synthesis of suitable adsorbents for the adsorption-based separation of R32, R22, R125, R134a, R143a ...
