    • PROBLEM TO BE SOLVED: To provide a freezing circuit which uses a scroll compressor as a compressor, uses an unsaturated fluorinated hydrocarbon refrigerant as a refrigerant, uses an ether-based lubricant such as a polyalkylene glycol as a freezer oil, and prevents the production of a waxy solid matter causing the clogging of a freezing circuit and the deterioration of a freezing performance in the freezing circuit.
      SOLUTION: The freezing circuit is characterized by adding a polymerization inhibitor to an ether-based lubricant such as a polyalkylene glycol and further adding a polyoxyalkylene structure-free lubricant component such as an ether-based lubricant, an alcohol-based abrasion-reducing agent, an olefin-based abrasion-reducing agent, a polyolefin-based lubricant, an alkyl aromatic lubricant or a silicone-based lubricant, or a metal-inactivating agent such as benzotriazole. Thus, the production of a waxy solid matter in the freezing circuit can be prevented.

    • 要解决的问题:为了提供一种使用涡旋压缩机作为压缩机的冷冻回路,使用不饱和氟化烃制冷剂作为制冷剂,使用作为冷冻机油的聚亚烷基二醇等醚类润滑剂,并防止 产生导致冻结回路堵塞的蜡状固体物质和冻结回路中的冷冻性能的劣化。 解冻方法:冷冻回路的特征在于将聚合抑制剂加入到诸如聚亚烷基二醇的醚基润滑剂中,并进一步加入无氧化烯无结构的润滑剂组分如醚基润滑剂, 烯烃类减磨剂,聚烯烃系润滑剂,烷基芳香族润滑剂,硅酮系润滑剂,苯并三唑等金属钝化剂等。 因此,可以防止在冷冻回路中产生蜡状固体物质。 版权所有(C)2011,JPO&INPIT
