Problems solved by technology

[0008] However, HFO-1132 is a compound containing unsaturated bonds in its molecule, and since it is a compound with a very short life in the atmosphere, it is saturated with conventional HFCs and HCFCs under repeated compression and heating conditions in thermal cycles. Problems with poorer stability of HFCs compared to HCFCs

Embodiment

[0270] Hereinafter, the present invention will be further described in detail with reference to Examples (Examples 1-43, Examples 64-106, Examples 127-169) and Comparative Examples (Examples 44-63, Examples 107-126, Examples 170-189). In each example, the composition for thermal cycle systems mixed with the compounding (mass %) shown in Tables 2-5 was manufactured.

[0271] Here, the components shown below were used as the working medium, stabilizer and refrigerating machine oil.

[0272] The composition (mass ratio) of working media 1-30 is shown in Table 2. In addition, "HFO-1132" in Table 2 means the mixture of equal amounts of HFO-1132(E) and HFO-1132(Z).

Abstract

Provided are a composition for a heat cycle system including a working medium for the heat cycle having a low global warming potential and high stability that can be substituted for R410A and a heat cycle system using this composition. A composition for a heat cycle system including a working medium for the heat cycle including 1,2-difluoroethylene and stabilizers for suppressing deterioration of the working medium for the heat system such as an agent to improve oxidation resistance, agent to improve heat resistance, metal inactivating agent, and the like, and a heat cycle system using this composition for a heat cycle system.

Description

technical field [0001] The present invention relates to a composition for a thermal cycle system and a thermal cycle system using the composition. Background technique [0002] In this specification, the compound abbreviation of a halogenated hydrocarbon is described in the parentheses after a compound name, and the abbreviation is used instead of a compound name in this specification as needed. [0003] In the past, as refrigerants for refrigerators, refrigerants for air conditioners, working media for power generation systems (waste heat recovery power generation, etc.), working media for latent heat transport devices (heat pipes, etc.), and secondary cooling media, etc. Chlorofluorocarbons (CFCs) such as chlorotrifluoromethane and dichlorodifluoromethane, and hydrochlorofluorocarbons (HCFCs) such as chlorodifluoromethane are used. However, CFCs and HCHCs have been pointed out to have an impact on the stratospheric ozone layer, and are currently subject to regulation. ...
