Problems solved by technology

[0008] However, HFO-1132 is a compound containing an unsaturated bond in its molecule, and since it has a very short atmospheric lifetime, it is different from conventional saturated hydrofluorocarbons called HFCs and HCFCs, Hydrochlorofluorocarbons are less stable than hydrochlorofluorocarbons, and there is a reduction in lubricity in the thermal cycle system

Embodiment

[0252] Hereinafter, the present invention will be described in more detail with reference to Examples (Examples 1 to 120), Conventional Examples (Examples 121 to 124), and Comparative Examples (Examples 125 to 154). In each example, the composition for thermal cycle systems which mixed and melt|dissolved 50 g of working media and 50 g of refrigerating machine oils was manufactured by the combination shown in Tables 2-5. Therefore, the composition for the thermal cycle system in this example consists of 50% by mass of the working medium and 50% by mass of refrigerating machine oil.

[0253] Here, the components shown below are used as the working medium and refrigerating machine oil.

[0254] 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).

[0255] In addition, the working medium 31 is R410A (an approximate azeotropic mixed medium in which the mass rat...

Abstract

Provided are a composition for a heat cycle system having good lubricating properties including a working medium for the heat cycle having a low global warming potential 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, oxygen-containing synthetic oil (ester refrigeration oil, ether refrigeration oil, or the like), and refrigeration oil such as hydrocarbon refrigeration oil or 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. ...
