PROBLEM TO BE SOLVED: To provide a refrigerator oil composition satisfying both sludge dispersibility and prevention of abrasion and seizure in a sliding part composed of aluminum and/or iron of a compressor for the refrigerator, and to provide the compressor and freezing equipment using the same. SOLUTION: The refrigerator oil composition comprises an imide compound in an amount of 0.01-5 mass% based on the total amount of the refrigerator oil composition in a base oil which is at least one kind selected from a mineral oil and a synthetic oil. The compressor and the freezing equipment are obtained by using the composition. COPYRIGHT: (C)2007,JPO&INPIT

There is obtained a lubricating oil having good solubility with both HFC refrigerant and contaminants by adding PAG having a viscosity of not more than 70cSt (40 DEG C) to a synthetic lubricating oil, such as polyvinyl ether and ester oils at an amount of not less than 0.1wt% and not more than 20wt% (desirably, not less than 2wt% and not more than 10wt%). Therefore, in a refrigerating/air-conditioning machine equipped with a compressor using this present lubricating oil together with a HFC refrigerant as a working fluid, deflection in the ratio of the mixture within the machines is not caused and, consequently, the efficiency for washing capillary tubes is not reduced. In that case, a high-reliable refrigerating/air-conditioning machine can be obtained at a low price without any modification of the refrigerating/air-conditioning machine.

PROBLEM TO BE SOLVED: To give seizure resistance to allow repeating tightening and loosening to a threaded joint for steel pipe composed of a pin and a box contacting surfaces including a threaded part and non-threaded metal contact part respectively without applying liquid lubricant including heavy metal powder. SOLUTION: Porous metal substrate treatment layer of porosity 5-80%, thickness 1-30 μm, and preferably hardness Hv 50-250 is formed on the contact surface of at least one of the pin and the box removing dispersed matter after projection or spraying plating, or dispersion plating, and solid lubricating film or a layer of liquid lubricant film not including heavy metal powder is formed not to exceed 100 μm in total thickness with a lower layer.
