えられている。2. Description of the Related Art Conventionally, dichlorodifluoromethane (R-12) and monochlorodifluoroethane (R-22) have been frequently used as refrigerants for refrigerators. However, each of the above refrigerants is released into the atmosphere due to its high ozone depletion potential and reaches the ozone layer above the earth, destroying this ozone layer. This destruction of the ozone layer is caused by chlorine groups (Cl) in the refrigerant. Therefore, a refrigerant containing no chlorine group, for example, difluoromethane (HFC-32, R-32), trifluoromethane (H
FC-23, R-23), pentafluoroethane (HF
C-125, R-125), 1,1,1,2-tetrafluoroethane (HFC-134a, R-134a),

R-143a), a fluorocarbon-based refrigerant containing no chlorine group and hydrogen (FC-based refrigerant), or a mixture of these HFC-based refrigerants and FC-based refrigerants is considered as an alternative refrigerant to the refrigerant.

るようにすることが強く求められている。[0004] However, these hydrocarbon-based refrigerants are all colorless and have a peculiar smell, but cannot be found immediately even if the refrigerant leaks. Therefore, if these refrigerants leak, the oxygen in the room becomes insufficient due to lack of oxygen, and there is a problem that an accident such as death of a person who enters the room may occur. In addition, these hydrocarbon-based refrigerants are flammable, and if leaked from a refrigerating device or the like, there is a danger that they will come into contact with an ignition source, explode, or be inhaled by inhalation. In order to solve this problem, a refrigerant colored by adding a colorant to an HFC-based or FC-based refrigerant has been proposed and is commercially available (for example, Daitel: trade name, manufactured by Daikin Co., Ltd. Refrigerant colored pink). There is a strong need to be able to detect even a small amount of refrigerant leakage immediately.
