摘要： An object of the present invention is to provide a refrigerant in which an odorant is added, the odorant being compatible with refrigerants and refrigerating device oils, and having no reactivity with refrigerating device oils and materials forming refrigerating circuits, and to provide a refrigerating device in which the refrigerant is circulated in the refrigerating circuit. A refrigerant whose main component is a hydrocarbon having 1 to 4 carbon atoms, or a flammable hydrocarbon fluoride obtained when one or more hydrogen atoms of the hydrocarbon is substituted by fluorine atoms, the refrigerant containing a tetrahydrothiophene as an odorant, and a refrigerating device in which the refrigerant is circulated are provided.

摘要： A Stirling refrigerator, which prevents oil rising, makes oil seal bellows have long-life, and includes a housing, cylinder, piston, piston rod and an oil seal bellows. The oil seal bellows seals a space between the housing and the cylinder, wherein a tip end of the oil seal bellows is sealed and fixed on the piston or on the piston rod inside the cylinder, and a base end of the oil seal bellows is installed on the housing. The oil seal bellows reciprocates with a stroke, wherein the tip end of the oil seal bellows is compressed to a compression side from a position of free length then returns to the position of free length.

摘要： The present invention is to provide a refrigerant compressor comprising a compressing element driven by a rotary shaft, for compressing and discharging a sucked HFC type refrigerant or refrigerant mainly comprising the HFC type refrigerant by the compressing element, where a rotary shaft applied with the plasma sulphonitriding treatment on the surface is used as the rotary shaft. Or a vane applied with the plasma sulphonitriding treatment on the surface of a vane made of a steel equivalent to a high speed tool steel vane or a steel equivalent to a stainless steel is used. Accordingly, a refrigerant compressor comprising a rotary shaft or a vane having a low friction coefficient in a sliding portion on the surface of the rotary shaft or the vane and a high wear resistance can be provided even in the case an ester type refrigerator oil or an ether type refrigerator oil is used as the refrigerator oil and an HFC type refrigerant is used.

摘要： 1,1,1,2-Tetrafluoroethane is used in a refrigerator as the refrigerant, while a polyolester oil which is well compatible with the refrigerant is used as the base oil and a phenolic antioxidant, a specified amine and a phosphoric triester are added thereto to give a refrigerator oil composition. Thus the hydrolysis of the polyolester oil can be prevented to thereby protect the sliding members such as a roller and a vane from the corrosion and wear which are caused by the hydrolysis.
