ROTARY COMPRESSOR

摘要

A rotary compressor includes: a vertically-positioned airtight compressor housing having an upper section including a discharge portion of a refrigerant, and a lower section including an inlet unit of the refrigerant and storing lubricant oil; a compressing unit, disposed in the lower section, compressing the refrigerant sucked in via the inlet unit and discharging the refrigerant from the discharge portion; a motor, disposed in the upper section, driving the compressing unit via a rotation shaft; and an accumulator attached to the compressor housing and connected to the inlet unit. Inside the accumulator and/or the compressor housing, silicon dioxide having a crystal structure containing a vacancy with a diameter equal to or less than a diameter of a water molecule or a composite including silicon dioxide having a crystal structure containing a vacancy with a diameter equal to or less than that of the water molecule is placed.

1. A rotary compressor comprising:
a vertically-positioned airtight compressor housing having an upper section in which a discharge portion of a refrigerant is provided and a lower section in which an inlet unit of the refrigerant is provided and lubricant oil is stored; a compressing unit that is disposed in the lower section of the compressor housing and that compresses the refrigerant sucked in via the inlet unit and discharges the refrigerant from the discharge portion; a motor that is disposed in the upper section of the compressor housing and drives the compressing unit via a rotation shaft; and an accumulator that is attached to a side section of the compressor housing and is connected to the inlet unit of the refrigerant, wherein, inside the accumulator and/or inside the compressor housing, silicon dioxide having a crystal structure which contains a vacancy with a diameter equal to or less than a diameter of a water molecule, or a composite which includes silicon dioxide having a crystal structure which contains a vacancy with a diameter equal to or less than the diameter of the water molecule is placed.
