Abstract

A refrigeration cycle device (100) is provided with: a main circuit section (101), which has a compressor (1), a condenser (3), and an expansion valve (4), and in which a mixed refrigerant flows through the compressor (1), the condenser (3) and the expansion value (4) in this order, said mixed refrigerant having a first refrigerant, and a second refrigerant having a density that is higher than that of the first refrigerant; and a composition adjustment section (102) connected to the main circuit section (101). The composition adjustment section (102) has a composition separator (6), a refrigerant storing container (11), and a composition adjustment circuit (30). The composition separator (6) has a composition separation film (7) that separates the mixed refrigerant in the gas state into the first refrigerant and the second refrigerant, said mixed refrigerant flowing in from the main circuit section (101). The refrigerant storing container (11) stores the first refrigerant separated bymeans of the composition separator (6). The composition adjustment circuit (30) connects the main circuit section (101), the composition separator (6), and the refrigerant storing container (11) to each other. The composition adjustment circuit (30) has a switching device (40).

Description

technical field [0001] The invention relates to a refrigeration cycle device and a component adjustment device. Background technique [0002] Conventionally, there is a technique of increasing the refrigerating capacity of a refrigeration cycle device by increasing the concentration of some of the components of a mixed refrigerant flowing through the refrigeration cycle device. For example, Japanese Unexamined Patent Application Publication No. 4-263745 (Patent Document 1) describes a refrigeration device capable of varying the composition ratio of a mixed refrigerant. This refrigerating device includes a refrigerant separator having a functional membrane that facilitates permeation of a part of refrigerant in a mixed refrigerant. The refrigerant separator is connected between the condenser and the evaporator.
