Research on the Thermophysical Properties and Cycle Performances of R1234yf/R290 and R1234yf/R600a

International Journal of Thermophysics, 2021
R134a, commonly used for automotive air conditioning, will be phased out due to its high global warming potential, while R1234yf/R290 and R1234yf/R600a were considered as two potential alternatives owing to their excellent environmental characteristics.

Investigation on the density of Al₂O₃/R1234yf, TiO₂/R1234yf and CuO/R1234yf nano-refrigerants

Proceedings of the Institution of Mechanical Engineers, Part N: Journal of Nanomaterials, Nanoengineering and Nanosystems, 2022
Nano-enhanced refrigerant is one of the promising heat transfer fluids in refrigeration systems. It has the capability to boost the efficiency of vapour compression refrigeration and air conditioning systems. In heat transfer application, the density of the fluid plays a crucial role in identifying various heat transfer characteristics such as the ...

Liquid viscosity of low-GWP refrigerant mixtures (R32 + R1234yf) and (R125 + R1234yf)

The Journal of Chemical Thermodynamics, 2015
Abstract In this work, the viscosity of R1234yf, (R32 + R1234yf), and (R125 + R1234yf) in one-phase liquid was measured. The combined expanded uncertainty of viscosity measurement apparatus of confidence of 0.95 (k = 2) is about 2.0%. The measurements of mixtures containing (30.0, 50.0, and 70.0) wt% R32 or R125 were carried out between T = (283.0 ...

Thermodynamic analysis of linear compressor using R1234yf

International Journal of Refrigeration, 2019
Abstract Without crank mechanism, linear compressors can provide significant advantages such as selection of refrigerants, miniaturization, high efficiency, and non-start/stop. Free motion of piston means that displacement can be modulated according to heat load and friction loss of refrigerants. R1234yf is a synthetic refrigerant with global warming

The refrigerant R1234yf in air conditioning systems

Energy, 2011
Abstract Experiments were conducted for a typical R134a compact European automotive air conditioning system equipped with an internally controlled variable displacement compressor, minichannel condenser, TXV, and minichannel evaporator. A “drop-in” R1234yf system was tested together with two modified R1234yf systems with the primary goal to document ...

Isobaric Heat Capacity Measurements of Supercritical R1234yf

Journal of Chemical & Engineering Data, 2018
R1234yf (2,3,3,3-tetrafluoropropene) is a low global warming potential (GWP) replacement for R134a, a fluid commonly used as a refrigerant in domestic and automotive air conditioning systems and as a working fluid in organic Rankine cycles. The use of R1234yf in energy conversion cycles requires an accurate determination of its thermophysical ...

Phase behavior of R1234yf and R600a in pentaerythritol tetranonanoate

International Journal of Refrigeration, 2020
Abstract 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) and isobutane (R600a) regarded as green refrigerants have received much attention in the refrigeration industry. Phase equilibrium between refrigerant and lubricant has a critical impact on the performance of a compression-refrigeration cycle.

Flow boiling of R1234yf in a 1 mm diameter channel

International Journal of Refrigeration, 2013
Abstract Since many HFC refrigerants have relatively large values of GWP, recent development efforts have been initiated to investigate halogenated olefins as possible refrigerants, with fluorinated propene isomers, in particular, having emerged as possible solutions.
