Experimental Study on the Solubility of R1234ze(E) in Polyol Ester Oils

open access: yesZhileng xuebao, 2020
R1234ze(E)(1,1,1,3-tetrafluoropropene) is extremely environmental-friendly and is currently considered as one of the alternative refrigerants. In this paper, the solubility of R1234ze(E) in two polyol ester oils was measured at temperatures ranging from 40 °C to 80 °C and pressures ranging from 0.123 MPa to 0.360 MPa.

Measurement of CO 2 + freon phase equilibria and extension of the predictive E-PPR78 equation of state to freon-containing systems

open access: yes, 2015
International audienceScientific topic: 2 (equations of state) Abstract Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) have a high ozone depletion potential (ODP) and hydrofluorocarbons (HFCs) are high global warming potential (GWP ...

The distribution over an impacting T-junction of two-phase R32 under heat pump conditions [PDF]

open access: yes, 2017
This experimental work studies the distribution of a two-phase refrigerant flow over a horizontal impacting T-junction. A setup was built which consists of two parts: a flow conditioner and a test section.

Thermal conductivity measurements for trans-1,3,3,3-Tetrafluoropropene (R1234ze(E)) in liquid phase

open access: yesInternational Journal of Refrigeration
International regulations, such as the European Regulation EU No 517/2014, are pushing the refrigeration, heat pumps and air conditioning sectors to find suitable low-GWP working fluids as alternatives to the currently widespread high-GWP refrigerants, such as R134a and R410A.

Comparison on Evaporation Heat Transfer between R32/R1234yf and R32/R1234ze(E) Flowing in Horizontal Microfin Tubes [PDF]

open access: yes, 2016
Refrigerant mixtures R32/R1234yf and R32/R1234ze(E) are considered to be the low GWP alternatives of R32 and R410A for air conditioners. However, according to the recent reports, the severe heat transfer degradation is encountered during the evaporation ...
