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.
本发明的目的是提供一种添加了臭味剂的制冷剂,该臭味剂与制冷剂和制冷设备油兼容,并且与制冷设备油和构成制冷回路的材料没有反应性,并提供一种制冷剂在制冷回路中循环的制冷设备。
本发明提供了一种制冷剂,其主要成分是具有 1 至 4 个碳原子的碳氢化合物,或当碳氢化合物的一个或多个氢原子被
氟原子取代时得到的易燃碳氢化合物
氟化物,该制冷剂含有作为气味剂的
四氢噻吩,并提供了一种制冷剂在其中循环的制冷设备。
