Dichlorodifluoromethane (R-12) has been widely used as a radiator gas in pressure threshold Cherenkov detectors for high-energy particle physics. However, that compound is becoming unavailable due to the Montreal Protocol. To find a replacement with suitably high refractive index, we use a combination of theory and experiment to examine the polarizability and refractivity of several non-ozone-depleting compounds. Our measurements show that the fourth-generation refrigerants R-1234yf (2,3,3,3-tetrafluoropropene) and R-1234ze(E) (-1,3,3,3-tetrafluoropropene) have sufficient refractivity to replace R-12 in this application. If the slight flammability of these compounds is a problem, two nonflammable alternatives are R-218 (octafluoropropane), which has a high Global Warming Potential, and R-13I1 (trifluoroiodomethane), which has low Ozone Depletion Potential and Global Warming Potential but may not be sufficiently inert.

“…On the other hand, there is recently a renewed interest in the use of Trifluoroiodomethane (R13I1) refrigerant as the working fluid in the thermodynamic systems of the production units [23,24], however studies on the EERC system using R13I1 as working fluid in the field of refrigeration were not found in the literature. While this fluid has excellent thermo-physical properties [25] like R134a, good safety, and negligible environmental impact [Zero Ozone Depletion Potential (ODP=0), Zero Global Warming Potential (GWP=0)] [26], so it can be considered as an alternative refrigerant. Considering the increasing restrictions imposed by the international Montreal and Kyoto protocols, the refrigerant can be selected as a possible new working fluid in the EERC system and can be recommended as a good candidate for replacing the above working fluids and especially the phase-out R134a (HFC), which is widely used in EERC system, due to its good performances in the EERC system, unfortunately, it has high global warming potential (GWP=1430).…”

“…Therefore, the present study aims to investigate theoretically the performance of the EERC system in terms of coefficient of performance (COP), entrainment ratio (µ), exergy destruction and exergy efficiency using the eco-friendly R13I1 refrigerant as a substitute to the traditional R134a fluid. The fundamental environmental and thermodynamic properties of the investigated refrigerants are shown in Table 1 [26][27][28]. The thermodynamic properties of the working fluids greatly affect the cycle performances.…”

Knowing that from 2030 refrigerants used in refrigerating engineering should have a global warming potential (GWP) of less than 150. Searching for eco-friendly refrigerants with good performance and minimal environmental impact to substitute conventional working fluids such as R134a (GWP=1430) represents a great challenge for researchers. The present research aims to investigate and compare the performances of the eco-friendly refrigerant R13I1 (Zero GWP) used as a possible new working fluid in the ejector-expansion refrigeration cycle (EERC) with the commonly used R134a which has good performances but a high GWP. To reach this objective, a numerical program was developed using MATLAB software to evaluate the coefficient of performance (COP), the entrainment ratio (µ), the exergy destruction and the exergy efficiency for both refrigerants. Furthermore, the effect of the diffuser efficiency of the ejector on the COP and the compressor work was explored. Furthermore, the effect of the diffuser efficiency of the ejector on the COP, and the compressor work were explored. The simulation was realized for Tc selected between 30 and 55 °C and Te ranging between -10 and 10 °C. Results proved that the use of R13I1 as a working fluid in the EERC system exhibited a higher COP, µ, and exergy efficiency, as well as lower exergy destruction compared with R134a under the same operating temperatures. On another hand, the energetic analysis revealed that as Tc increases the COP and µ decrease. However, as Te varies from -10 and 10 °C, the COP and µ increase. Regarding exergy analysis, it should be noted that both exergy destruction and exergy efficiency are sensitively influenced by Tc more than Te. Overall, the study confirms that R13I1 could be a suitable substitute for the phase-out R134a in terms of performance and environmental protection.

Candidate eco-friendly gas mixtures for MPGDs

Abstract: Modern gas detectors for detection of particles require F-based gases for optimal performance. Recent regulations demand the use of environmentally unfriendly F-based gases to be limited or banned. This review studies properties of potential eco-friendly gas candidate replacements.
