[0002] R410A is currently used as an air conditioning refrigerant for home air conditioners etc. R410A is a two-component mixed refrigerant of difluoromethane (CH 2 F 2 : HFC-32 or R32) and pentafluoroethane (C 2 HF 5 : HFC-125 or R125), and is a pseudo-azeotropic composition.

[0003] 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.

[0004] For this reason, various low-GWP mixed refrigerants that can replace R410A have been proposed (WO 2015 / 141678).

[0005] US-A-2017 / 058173 discloses a working fluid for heat cycle, which contains at least two members selected from a saturated hydrofluorocarbon and a hydrofluorocarbon having a carbon-carbon double bond other than 1,2-difluoroethylene, and 1,2-difluoroethylen.

[0006] US-A-2017 / 058171 describes a working fluid for heat cycle, which contains an azeotropic-like composition consisting of trans-1,2-difluoroethylene, and difluoromethane and / or pentafluoroethane.Summary of InventionTechnical Problem

Description of Embodiments

[0014] The present inventors conducted intensive studies to solve the above problem, and consequently found that a mixed refrigerant comprising trans-1,2-difluoroethylene (HFO-1132(E)), difluoromethane (R32), 1,3,3,3-tetrafluoropropene (R1234ze), and carbon dioxide (CO 2 ) has the above properties.

[0015] The present invention has been completed as a result of further research based on this finding. The present invention includes the following embodiments. In the present specification the following definitions apply.Definition of Terms

[0016] The term "refrigerant" includes at least compounds that are specified in ISO 817 (International Organization for Standardization), and that are given a refrigerant number (ASHRAE number) representing the type of refrigerant with "R" at the beginning; and further includes refrigerants that have properties equivalent to those of such refrigerants, even though a refrigerant number is not yet given. Refrigerants are broadly divided into fluorocarbon compounds and non-fluorocarbon compounds in terms of the structure of the compounds. Fluorocarbon compounds include chlorofluorocarbons (CFC), hydrochlorofluorocarbons (HCFC), and hydrofluorocarbons (HFC). Examples of non-fluorocarbon compounds include propane (R290), propylene (R1270), butane (R600), isobutane (R600a), carbon dioxide (R744), and ammonia (R717).

[0017] The phrase "composition comprising a refrigerant" at least includes (1) a refrigerant itself (including a mixture of refrigerants), (2) a composition that further comprises one or more other components and that can be mixed with at least a refrigeration oil to obtain a working fluid for a refrigerating machine, and (3) a working fluid for a refrigerating machine containing a refrigeration oil. In the present specification, of these three embodiments, the composition (2) is referred to as a "refrigerant composition" so as to distinguish it from a refrigerant itself (including a mixture of refrigerants). Further, the working fluid for a refrigerating machine (3) is referred to as a "refrigeration oil-containing working fluid" so as to distinguish it from the "refrigerant composition."

[0018] When the term "alternative" is used in a context in which the first refrigerant is replaced with the second refrigerant, the first type of "alternative" means that equipment designed for operation using the first refrigerant can be operated using the second refrigerant under optimum conditions, optionally with changes of only a few parts (at least one of the following: refrigeration oil, gasket, packing, expansion valve, dryer, and other parts) and equipment adjustment. In other words, this type of alternative means that the same equipment is operated with an alternative refrigerant. Embodiments of this type of "alternative" include "drop-in alternative," "nearly drop-in alternative," and "retrofit," in the order in which the extent of changes and adjustment necessary for replacing the first refrigerant with the second refrigerant is smaller.

[0019] The term "alternative" also includes a second type of "alternative," which means that equipment designed for operation using the second refrigerant is operated for the same use as the existing use with the first refrigerant by using the second refrigerant. This type of alternative means that the same use is achieved with an alternative refrigerant.

[0020] The term "refrigerating machine" refers to machines in general that draw heat from an object or space to make its temperature lower than the temperature of ambient air, and maintain a low temperature. In other words, refrigerating machines refer to conversion machines that gain energy from the outside to do work, and that perform energy conversion, in order to transfer heat from where the temperature is lower to where the temperature is higher.

[0021] A refrigerant having a "WCF lower flammability" means that the most flammable composition (worst case of formulation for flammability: WCF) has a burning velocity of ≤ 10 cm / s according to the US ANSI / ASHRAE Standard 34-2013.1. Refrigerant1.1 Refrigerant Component

[0067] The refrigeration oil may further contain additives in addition to the base oil. The additive may be at least one member selected from antioxidants, extreme-pressure agents, acid scavengers, oxygen scavengers, copper deactivators, rust inhibitors, oil agents, and antifoaming agents.

[0068] A refrigeration oil with a kinematic viscosity of (5-400) x 10 -6< m 2< / s (5-400 cSt) at 40°C is preferable from the standpoint of lubrication.

[0069] The refrigeration oil-containing working fluid according to the present disclosure may further optionally contain at least one additive. Examples of additives include compatibilizing agents described below.3.2 Compatibilizing Agent

[0070] The refrigeration oil-containing working fluid according to the present disclosure may comprise a single compatibilizing agent, or two or more compatibilizing agents.

[0071] The compatibilizing agent is not limited, and can be suitably selected from commonly used compatibilizing agents.

[0072] Examples of compatibilizing agents include polyoxyalkylene glycol ethers, amides, nitriles, ketones, chlorocarbons, esters, lactones, aryl ethers, fluoroethers, and 1,1,1-trifluoroalkanes. The compatibilizing agent is particularly preferably a polyoxyalkylene glycol ether.4. Method for Operating Refrigerating Machine

[0073] The method for operating a refrigerating machine according to the present invention ("the present method") is a method for operating a refrigerating machine using the present refrigerant.

[0074] Specifically, the present method comprises circulating the present refrigerant in a refrigerating machine.Examples

[0075] The present invention is described in more detail below with reference to Examples.Example A

[0076] Mixed refrigerants were prepared by mixing HFO-1132(E), R32, R1234ze, and CO 2 at mass% based on their sum shown in Tables 1 to 6.

[0077] The GWP of R410A (R32=50% / R125=50%) and the mixed refrigerants was evaluated based on the values stated in the Intergovernmental Panel on Climate Change (IPCC), fourth report. The GWP of HFO-1132(E), which was not stated therein, was assumed to be 1 from HFO-1132a (GWP = 1 or less) and HFO-1123 (GWP = 0.3, described in WO 2015 / 141678). The refrigerating capacity of R410A and the mixed refrigerants was determined by performing theoretical refrigeration cycle calculations for the mixed refrigerants using the National Institute of Science and Technology (NIST) and Reference Fluid Thermodynamic and Transport Properties Database (Refprop 9.0) under the following conditions.

[0078] The COP ratio and the refrigerating capacity ratio of the mixed refrigerants relative to those of R410A were determined. The calculation conditions were as follows. Evaporating temperature: 5°C Condensation temperature: 45°C Degree of superheating: 5 K Degree of subcooling: 5 K Compressor efficiency: 70%

[0079] Tables 1-6 show these values together with the GWP of each mixed refrigerant. The COP and refrigerating capacity are ratios relative to R410A.

[0080] The coefficient of performance (COP) was determined according to the following formula.

[0081] A burning velocity test was performed using the apparatus shown in Fig. 1 in the following manner. First, the mixed refrigerants used had a purity of ≥ 99.5%, and were degassed by repeating a cycle of freezing, pumping, and thawing until no traces of air were observed on the vacuum gauge. The burning velocity was measured by the closed method. The initial temperature was ambient temperature. Ignition was performed by generating an electric spark between the electrodes in the center of a sample cell. The duration of the discharge was 1.0-9.9 ms, and the ignition energy was typically about 0.1-1.0 J. The spread of the flame was visualized using schlieren photographs. A cylindrical container (inner diameter: 155 mm, length: 198 mm) equipped with two light transmission acrylic windows was used as the sample cell, and a xenon lamp was used as the light source. The propagation of flame was photographed with a schlieren system using a collimating lens and a high-speed digital video camera (frame rate: 600 fps), and recorded as video data on a PC. From the video image, flame propagation rate Sb (cm / sec) was measured. The burning velocity (Su) is expressed as the volume of unburned gas consumed by the flame surface of a unit area per unit time and was calculated by using the following formula. Su = Sb * ρu / ρb ρu: adiabatic flame temperature (unburned) ρb: adiabatic flame temperature (burned) ρu represents the measurement temperature, and ρb represents the combustion of combustion gas and is calculated from isobaric specific heat.
