In the two-cylinder hermetic compressor, a first compression mechanism unit includes a first cylinder and a first piston, and a second compression mechanism unit includes a second cylinder and a second piston. A main bearing is disposed on one surface of the first cylinder, and an intermediate plate is disposed on another surface of the first cylinder. The intermediate plate is disposed on one surface of the second cylinder, and an auxiliary bearing is disposed on another surface of the second cylinder. A shaft is constituted by a main shaft portion which has a rotor attached thereto and is supported by the main bearing, a first eccentric portion having a first piston attached thereto, a second eccentric portion having a second piston attached thereto, and an auxiliary shaft portion supported by the auxiliary bearing. The diameter of the auxiliary shaft portion is set larger than the diameter of the main shaft portion.

Two-cylinder hermetic compressor

In the two-cylinder hermetic compressor, a main bearing is disposed on one surface of a first cylinder, an intermediate plate is disposed on another surface of the first cylinder, the intermediate plate is disposed on one surface of a second cylinder, and an auxiliary bearing is disposed on another surface of the second cylinder. A shaft is constituted by a main shaft portion which has a rotor attached thereto and is supported by the main bearing, a first eccentric portion having a first piston attached thereto, a second eccentric portion having a second piston attached thereto, and an auxiliary shaft portion supported by the auxiliary bearing. A thrust receiving portion is provided on a side of the second eccentric portion facing the auxiliary shaft portion, and the auxiliary bearing is provided with a thrust surface on which the end face of the thrust receiving portion slides while contacting therewith. The thrust surface is provided with a ring groove.

A main bearing is disposed on one surface of a first cylinder, an intermediate plate is disposed on another surface of the first cylinder, the intermediate plate is disposed on one surface of a second cylinder, and an auxiliary bearing is disposed on another surface of the second cylinder. A shaft is constituted by a main shaft portion, a first eccentric portion, a second eccentric portion, and an auxiliary shaft portion. A first eccentric portion center position (H) which is the center position of the first eccentric portion in height (H) is located at a position closer to the main bearing than a first piston center position (P) which is the center position of a first piston in height (P). A second eccentric portion center position (H) which is the center position of the second eccentric portion in height (H) is located at a position closer to the auxiliary bearing than a second piston center position (P) which is the center position of a second piston in height (P).

According to a compressor of the present invention, the compressor further comprises an oil separating mechanismwhich separates oil from the refrigerant gas discharged from the compressing mechanism, the oil separating mechanismincludes a cylindrical spacein which the refrigerant gas orbits, an inflow portionfor flowing the refrigerant gas discharged from the compressing mechanisminto the cylindrical space, a sending-out portfor sending out, from the cylindrical spaceto the one container space, the refrigerant gas from which the oil is separated, and an exhaust portfor discharging the separated oil and a portion of the refrigerant gas from the cylindrical space, and a center of the sending-out portis deviated in a direction opposite from the inflow portionfrom a center axis of the cylindrical space

To provide an air conditioner having an antibacterial and mold-proofing member which can be easily incorporated and has high effectiveness and a method for controlling the air conditioner. An air conditioner of the present invention having a heat exchanger and a blower for supplying the heat exchanger with air comprises an antibacterial and mold-proofing member which includes an antibacterial and mold-proofing component which will volatile at an ambient temperature and diffuse in the air conditioner, and also has a control mechanism for gradually evaporating which controls the release rate of the antibacterial and mold-proofing component to the inside of the air conditioner so that it becomes large at high humidity and small at low humidity.

Air conditioner and method for controlling air conditioner

The invention includes a step of supplying at least one heat control means of heating means and cooling means for conditioning the air temperature, and a step of manufacturing a fan for blowing air controlled by the heat control means, in which the step of manufacturing the fan includes a step of preparing a compound material having (i) glass fiber, and (ii) at least one copolymer of a copolymer produced from a monomer containing acrylonitrile and styrene, and a copolymer produced from styrene and a heat resistant monomer, a step of forming a molded part by molding the compound material, a step of assembling a fan by using the molded part, and a step of clearing the molded part of strain by annealing the fan by hot air circulation in a temperature range lower by about 5&deg; C. to about 20&deg; C. than the load deflection temperature, and in a wind velocity range of about 1 m/sec to about 3 m/sec. The fan having a load deflection temperature of about 100&deg; C. or more by a testing method of JIS K 7207 at a load of 18.5 kgf/cm,. The air conditioner is manufactured in this manner. In this constitution, the required annealing time is shortened, and the productivity is enhanced. Moreover, the flowability of the compound material is heightened, so that the molding performance is improved.
