Description

TECHNICAL FIELD

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.

BACKGROUND ART

R410A is currently used as an air conditioning refrigerant for home air conditioners etc. R410A is a two-component mixed refrigerant of difluoromethane (CH2F₂: HFC-32 or R32) and pentafluoroethane (C₂HF₅: 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).

DESCRIPTION OF EMBODIMENTS

The present inventors conducted intensive studies to solve the above problem, and consequently found that a mixed refrigerant comprising R32, HFO-1132(E), and R1234ze, as well as HFO-1132a has the above properties.

The present disclosure has been completed as a result of further research based on this finding. The present disclosure includes the following embodiments.

DEFINITION OF TERMS

In the present specification, 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). Non-fluorocarbon compounds include propane (R290), propylene (R1270), butane (R600), isobutane (R600a), carbon dioxide (R744), ammonia (R717), and the like.

In the present specification, the phrase “composition comprising a refrigerant” at least includes (1) a refrigerant itself (including a mixture of refrigerants), (2) a composition that further comprises 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.”

In the present specification, 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.

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.

In the present specification, 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.

EXAMPLES

The present disclosure is described in more detail below with reference to Examples. However, the present disclosure is not limited to the Examples.

Mixed refrigerants were prepared by mixing R32, HFO-1132(E), R1234ze, and HFO-1132a at mass % shown in Table 1 based on their sum.

The GWP of R410A (R32=50%/R125=50%) and the above 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 PTL 1). The refrigerating capacity of R410A and the above 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.

For each of these mixed refrigerants, the COP ratio and refrigerating capacity ratio relative to those of R410A were determined. The calculation conditions were as follows:

Evaporating temperature: 5° C.Condensation temperature: 45° C.Superheating temperature: 5 KSubcooling temperature: 5 KCompressor efficiency: 70%

Table1 shows these values together with the GWP of each mixed refrigerant. The COP and refrigerating capacity are ratios relative to R410A.

The coefficient of performance (COP) was determined by the following formula.

COP=(refrigerating capacity or heating capacity)/power consumption

The mixed refrigerants further comprising R1234yf in addition to R32, HFO-1132(E), R1234ze, and HFO-1132a have a GWP of 400 or less and a refrigerating capacity ratio of 85% or more relative to that of R410A, because they satisfy the following requirements.

Requirements

When the mass % of R32 is represented by x, the mass % of HFO-1132(E) is represented by y, the total mass % of R1234ze and R1234yf is represented by z, and the mass % of HFO-1132a is represented by a, provided that 1.5≤a≤10.0, based on the sum of R32, HFO-1132(E), R1234ze, R1234yf, and HFO-1132a, and r=R1234yf/(R1234ze+R1234yf),

if 1.5≤a≤4.6, coordinates (x,y,z) in a ternary composition diagram having R32 as a first vertex, HFO-1132(E) as a second vertex, and the sum of R1234ze and R1234yf as a third vertex are within the range of a figure surrounded by straight lines AB_r′, B_r′C_r, C_rD_r, D_rO, and OA that connect the following 5 points:
