Problems solved by technology

[0008] However, these HFOs are compounds containing unsaturated bonds in their molecules and have a very short lifetime in the atmosphere. Therefore, under the conditions of repeated compression and heating in thermal cycles, they are different from saturated HFOs such as conventional HFCs and HCFCs. Compared with hydrofluorocarbons and hydrochlorofluorocarbons, the stability is poor, and the lubricity may sometimes decrease in the thermal cycle system

Embodiment

[0365] Hereinafter, the present invention will be described in more detail with reference to examples, conventional examples, and comparative examples. In each example, 50 g of refrigerating machine oil was mixed and dissolved in 50 g of working medium, and 576 compositions for thermal cycle systems were prepared by selecting and combining working media 1 to 64 and refrigerating machine oils A to I shown below. Therefore, the composition for the thermal cycle system in this example is composed of 50% by mass of the working medium and 50% by mass of the refrigerating machine oil. In addition, depending on the working medium used, an antioxidant is added to form a composition for a thermal cycle system, which will be described below.

[0366] Here, as the working medium and the refrigerating machine oil, the following working medium and refrigerating machine oil are used. In addition, regarding the working medium, the compounds constituting the working medium are shown in Table...

Abstract

A composition for a heat cycle system which has excellent lubrication properties and which contains a heat cycle working medium usable as a substitute for R410A and having a low global warming potential, and a heat cycle system using said composition are provided. This composition for a heat cycle system contains a heat cycle working medium that contains an unsaturated fluorinated hydrocarbon compound of a specific structure, and a refrigerant oil which has an insulation breakdown voltage of 25kV or greater and a hydroxyl value of 0.1mgKOH / g or less, and for which the lowest temperature on the high temperature side of the phase separation temperature for separation from the heat cycle working medium is 35 DEG C or higher, and the highest temperature on the low temperature side is -60 DEG C or lower; this heat cycle system uses the aforementioned 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 written in the parentheses after a compound name, and in this specification, the abbreviation may be used instead of a compound name as needed. [0003] In the past, it was used as a working medium for 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.), secondary cooling media, and other heat cycle systems. , use chlorofluorocarbons (CFCs) such as chlorotrifluoromethane and dichlorodifluoromethane, and hydrochlorofluorocarbons (HCFCs) such as chlorodifluoromethane. However, CFCs and HCFCs have been pointed out to have an impact on the stratospheric ozo...
