Embodiment

[0255] Hereinafter, the present invention will be further described in detail with reference to Examples (Examples 1 to 257), Conventional Examples (Examples 258 to 265), and Comparative Examples (Examples 266 and 267). In each case, a composition for a thermal cycle system obtained by mixing and dissolving 50 g of a working medium for thermal cycle and 50 g of refrigerating machine oil was produced by the combination shown in Tables 5 to 31. Therefore, the composition for a thermal cycle system in each example is composed of 50% by mass of the working medium for thermal cycle and 50% by mass of refrigerating machine oil.

[0256] Here, the components shown below are used as the working medium for thermal cycle and refrigerating machine oil. In addition, Tables 2 to 4 collectively show the compounds constituting the working medium for thermal cycles. Here, the working medium 1-8 for thermal cycle only contains HCFO-1224yd, and the working medium 9-56 for thermal cycle is a mediu...

Abstract

This composition for use in heat cycle system contains a refrigerant oil and a heat cycle working medium that contains 1-chloro-2,3,3,3-tetrafluoropropene.

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, for halogenated hydrocarbons, the compound abbreviation is described in parentheses after the compound name, and the abbreviation is used instead of the compound name in this specification as necessary. [0003] In the past, as refrigerants for refrigerators, refrigerants for air conditioners, working media for power generation systems (waste heat recovery and power generation, etc.), working media for latent heat transfer devices (heat pipes, etc.), and working media for thermal cycle systems such as secondary cooling media, Chlorofluorocarbons (CFC) such as monochlorotrifluoromethane and dichlorodifluoromethane, and hydrochlorofluorocarbons (HCFC) such as monochlorodifluoromethane are used. However, CFC and HCHC have been pointed out to have an impact on the ozone layer in the strat...
