In Fig. 2 and Fig. 3, reference numeral 1 denotes a closed container, inside which is an electric motor 12, a crankshaft 3 driven by the electric motor 12, and a rotatable crankshaft 3. A rotor 4 is fitted into the rotor 4, a cylindrical cylinder 5 houses the rotor 4, and the tip of the rotor 4 is in contact with the rotor 4. A compression screw having a vane 7 that partitions into a high pressure side and a low pressure side, a spring 8 that biases the vane 7, and an upper bearing 9 and a lower bearing 10 that close the upper and lower openings of the cylinder 5 and support the crankshaft 3. A groove 11 is accommodated, and frozen granulated oil 12 is stored in the lower part.

として使用されてきた。Dichlorodifluoromethane (R12 (CC

。On the other hand, trifluorobromomethane (R13B1 (Car

蝕し、摩耗を速めたり、反応生成物を多く生じたりして
、圧４１１１１ｇ！１に致命的なｌＡ傷を与えた。The problem to be solved by the invention is that the bromine element (B'') contained in R13B1 (Car F3) has a weaker bonding force with the carbon element (C) than the chlorine element (Cj2), and is relatively weak. It decomposes at low temperatures and generates hydrogen bromide (HBr), etc. This corrodes the metal 44 materials and organic materials of the parts used in compression I, accelerating wear and producing many reaction products. This caused a fatal 1A injury to 41111g!1.

。For this reason, the usable temperature range of R1381 (CBr F3) is low, and its use is limited to reciprocating dynamic pressure M! The machine was limited. In particular, when R13B1 (Car F3) is mixed with other refrigerants with higher boiling points and used in rotary pressure 8 machines as shown in Figures 2 and 3, it is affected by the heat of compression of the other refrigerants. As a result, the discharge temperature becomes high, and the sliding portions between the vanes 7 and the rotor 4 become high in temperature due to store heat disturbance, causing the refrigerant to decompose, causing ρ-water buildup and wear.

となっていた。In particular, iron-based materials have traditionally been used for the rotor of rotary compressors, but due to their large coefficient of friction, high calorific value, and high reactivity with hydrogen bromide, they have become even more difficult to use as refrigerants. Decomposition was accelerated, and this decomposed refrigerant corroded the insulation coating and insulating paper of the electric α section, causing burnout of the electric VJ machine.

率の商い回転圧縮機が得られる。Effect With the above configuration, the carbide layer improves wear resistance and corrosion resistance in the contact area between the vane tip and the rotor surface, where the sliding conditions are most severe, and can suppress wear on the sliding part. Even if iron-based materials are used, it is possible to use a mixture of R13B1 (CBr F3) and other refrigerants with higher boiling points as the refrigerant, resulting in a compact and highly efficient rotary compressor.

A crankshaft 3 is driven by the J machine 2, and a rotor 4 fitted on the crankshaft 3 rotates with a part of its outer periphery contacting the inner periphery of a cylindrical cylinder 5. As the rotor 4 rotates, the vanes 7 are urged by the springs 8 and reciprocate vJ in the guide groove 6 while contacting the outer periphery of the rotor 4. Due to this movement, the Q thread refrigerant sucked in from the suction pipe 13 is compressed inside the cylinder 5, its pressure and temperature are increased, and the refrigerant is discharged through the discharge pipe 14.

penetrates through the guide groove 6 and performs a lubricating action. vane 7
The contact area between the tip of the rotor 4 and the rotor 4 is under very severe lubrication, but since a carbide layer 16 is formed on the surface of the rotor 4, even if the oil film is broken, the rotor body 15 made of iron-based material will not be subject to severe wear. It will not rust or corrode. Therefore, the reliability of the rotary compressor can be ensured.
