A scroll member for scroll compressor contains a phenol aralkyl resin and a glass fiber and has feature that the dimensional change rate of the member is 0.05% or below under a chemical stability test condition conducted in an atmosphere in which a refrigerant and a refrigerating machine oil coexist at a high temperature and a high pressure, thereby making the resin scroll member practical and chemically stable. The scroll member may further contain a phenol resin and/or glass beads. The scroll member may be formed by a heat treatment having stepwise temperature increase of a molded material from an initial temperature range of 120 to 140° C. to a final temperature range of 170 to 177° C. The heat treatment can be implemented sequentially, e.g., for four hours or more at a temperature range of 120 to 140° C., for four hours or more at a temperature range of 140 to 170° C., and for four hours or more at a temperature range of 170 to 177° C.
A member for a compressor comprising a phenol group resin and a glass material wherein the dimensional change rate of the member is 0.05% or below under a chemical stability test condition conducted in an atmosphere in which a refrigerant and a refrigerating machine oil coexist at a temperature of 150° C. and a pressure of 3.6 Mpa.
A member for a compressor comprising a phenol group resin and a glass material, wherein the member is formed by heat treatment having stepwise temperature increase of a molded material from an initial temperature range of 120 to 140° C. to a final temperature range of 170 to 177° C.
A method for manufacturing a scroll member in a scroll compressor comprising the steps of:
A scroll compressor comprising a compression chamber and a scroll member, wherein the scroll member is made of a phenol group resin and a glass material wherein the dimensional change rate of the member is 0.05% or below under a chemical stability test condition conducted in an atmosphere in which a refrigerant and a refrigerating machine oil coexist at a temperature of 150° C. and a pressure of 3.6 MPa.
A scroll compressor comprising a compression chamber and a scroll member, wherein the scroll member is formed by the steps of:
