Abstract

The creation of new age refrigerants might be the answer to the issue of an Earth-wide rise in temperature. Hence, while choosing new refrigerants a careful process is required. The general effect of any refrigerant substance on global warming, energy efficiency, ozone depletion, cost-effectiveness, chemical stability, and safety ought to be assessed. This paper sums up the experimental and numerical investigations directed with the globally accepted R1234yf refrigerant. The paper’s principal points are to assess the capability of the hydro-fluoro-olefin (HFO) refrigerant mainly R1234yf utilized in the refrigeration system (vapor compression systems, domestic refrigeration system) and to explore its utilization as an eco-friendly refrigerant. In the vapor compression refrigeration system, the cooling capacity and coefficient of performance of R1234yf are found to be less, 9% and 11%, respectively compared to that of R134a. But the power consumption of the system with R1234yf increased between 1.6% and 6.7% when compared to R134a. This paper likewise assists with recognizing the gap in the past research works and explores the possibilities for additional works.

环保型氢氟烯烃(HFO)制冷剂r1234yf的性质与性能:第一部分

新时代制冷剂的发明可能是解决全球气温上升问题的答案。因此，在选择新的制冷剂时，需要仔细的过程。任何制冷剂物质对全球变暖、能源效率、臭氧消耗、成本效益、化学稳定性和安全性的一般影响都应该进行评估。本文总结了采用国际通用的R1234yf制冷剂进行的试验和数值研究。本文的重点是评价以R1234yf为主的氢氟烯烃(HFO)制冷剂在制冷系统(蒸汽压缩系统、家用制冷系统)中的性能，并探讨其作为环保制冷剂的利用。在蒸汽压缩制冷系统中，R1234yf的制冷量和性能系数分别比R134a低9%和11%。但与R134a相比，R1234yf系统的功耗增加了1.6%至6.7%。本文同样有助于认识到过去研究工作中的差距，并探讨了额外工作的可能性。
