Known examples of such substitutes include “HFC-410A,” which is a mixture of HFC-32 and HFC-125, “HFC-404A,” which is a mixture of HFC-125, HFC-134a, and HFC-143a, etc.Such substitutes have various applications, such as heat transfer media, refrigerants, foaming agents, solvents, cleaning agents, propellants, and fire extinguishers, and are consumed in large amounts. However, since these substances have a global warning potential (GWP) several thousand times higher than that of CO, many people are concerned that their diffusion may affect global warming. As a global warming countermeasure, the substances are collected after being used; however, not all of them can be collected, and their diffusion due to leakage, etc., cannot be disregarded.

NON-OZONE DEPLETING AND LOW GLOBAL WARMING REFRIGERANT BLENDS

Non ozone depleting and non flammable refrigerant compositions with GWPs between 1,000 and 1600 ITH which may replace R404A and R507 in refrigeration systems. 15. A refrigerant composition consisting only of the components as claimed in .16. A refrigerant composition as claimed in having a Global Warming Potential greater than 1000. This invention relates to refrigerant compositions.Chlorofluorocarbons (CFCs) such as CFC12 and CFC502 and hydrochlorofluorocarbons (HFCs) such as HCFC22 migrate to the stratosphere where they are broken down by ultra violet light producing chlorine atoms that destroy the ozone layer. These Ozone Depleting Substances (ODS) are in the process of being replaced by non-ozone depleting alternatives such as hydrofluorocarbons (HFCs) which are non-flammable, efficient and of low toxicity. In certain applications, particularly but not specifically related to low temperature refrigeration systems often used in supermarkets, R502 was the main refrigerant of choice due largely to its lower discharge temperature compared to R22. As a consequence of the global environmental agreement embodied in the Montreal Protocol, R502 has been banned. R502 has been largely replaced by the HFCs R404A and R507. However R404A and R507, while being excellent refrigerants in terms of energy efficiency, non-flammability, low toxicity and thermodynamic properties, nevertheless have GWPs which are at the high end of the commonly used HFCs.It is an object of this invention to provide refrigerant compositions which have Global Warming Potentials (GWP) exceeding 1,000 but less than 1600 on an Integrated Time Horizon (ITH) of 100 years. In this specification the numerical value for Global Warming Potential (GWP) refer to an Integrated Time Horizon (ITH) of 100 years as contained in the Inter-Governmental Panel on Climate Change Fourth Assessment Report (AR4) and have no adverse effect on stratospheric ozone.

Provided is a mixed refrigerant having three types of performance; i.e., a refrigerating capacity equivalent to that of R410A, a sufficiently low GWP, and a lower flammability (Class 2L) according to the ASHRAE standard. Provided as a means for a solution is a composition comprising a refrigerant, the refrigerant comprising trans-1,2-difluoroethylene (HFO-1132(E)), difluoromethane (R32), and 2,3,3,3-tetrafluoro-1-propene (R1234yf), each in a specific concentration. 5.

The present disclosure relates to a composition comprising a refrigerant, use of the composition, a refrigerating machine having the composition, and a method for operating the refrigerating machine.R410A is currently used as an air conditioning refrigerant for home air conditioners etc. R410A is a two-component mixed refrigerant of difluoromethane (CHF: HFC-32 or R32) and pentafluoroethane (CHF: HFC-125 or R125), and is a pseudo-azeotropic composition.However, the global warming potential (GWP) of R410A is 2088. Due to growing concerns about global warming, R32, which has a GWP of 675, has been increasingly used.For this reason, various low-GWP mixed refrigerants that can replace R410A have been proposed (PTL 1).The present inventors performed independent examination, and conceived of the idea that no prior art had developed refrigerant compositions having three types of performance; i.e., a refrigerating capacity (also ...
