Abstract

Disclosed is a refrigerator oil composition characterized by containing a synthetic base oil and a partial hydrocarbyl ether of an aliphatic polyhydric alcohol condensate. This refrigerator oil composition is also characterized in that the aliphatic polyhydric alcohol condensate is a hindered glycol and / or a 4-20 molecule condensate of an aliphatic polyhydric alcohol having 3-6 hydroxy groups. This refrigerator oil composition is preferably used for compression type refrigerating machines wherein a hydrofluorocarbon, a natural refrigerant such as a hydrocarbon, carbon dioxide or ammonia, a mixed refrigerant of fluorinated methyl iodide and propene, or an unsaturated fluorinated hydrocarbon, a fluorinated ether, a fluorinated alcohol, a fluorinated ketone or one of their mixtures is used as a refrigerant.

Description

technical field [0001] The present invention relates to a refrigerating machine oil composition, and in more detail relates to a low friction coefficient, excellent energy saving, suitable for various refrigerating fields (automotive air conditioners, gas heat pumps, air conditioners, refrigerators, vending machines, showcases, hot water supply systems, flooring Heating) for compression-type refrigerators and refrigerator oil compositions for refrigeration systems. Background technique [0002] In general, a compression refrigerator consists of at least a compressor, a condenser, an expansion mechanism (expansion valve, etc.), an evaporator, or a dryer, and its structure is a mixed liquid of refrigerant and lubricating oil (refrigerator oil) Circulate in this closed system. In this type of compression refrigerator, although the type of device is also affected, generally, the temperature in the compressor is high and the temperature in the cooler is low, so the refrigerant a...
