Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an indoor unit for connecting a separate air conditioner, etc. A communication piping assembly with an outdoor unit and a refrigerating device using the communication piping assembly. [Known technology] In the past, one of the connected piping assemblies was equipped with two pipings covered with a heat-insulating material, and the outdoor unit and the indoor unit of the separate air conditioner were connected by a flared joint. This communication piping unit is used to expand the two ends of the piping with special tools when installing the air conditioner. The piping is used to connect the piping to the shut-off valve as the piping connection of the indoor unit and outdoor unit. However, since the above-mentioned communication piping assembly must be flared during installation, it is very labor-intensive, and there is also a problem that refrigerant leakage occurs due to the adhesion of dust or the difference in the quality of the processed product, which reduces the sealing performance. When a flammable refrigerant (such as propane, butane, ammonia, etc.) is used in the refrigerant system of the air conditioner, a leakage of the refrigerant from the flare joint may cause a fire. In addition, in the case of using HF0 refrigerants such as R410A and R32, which have a higher pressure than R22, have a lower molecular weight than R22, and are prone to gas leakage, or high-c0 2 refrigerants whose pressures are several times higher than R4, 0A, and R32. If you use a flared joint with low pressure strength, there will be a problem of gas leakage. As described above, the above-mentioned communication piping assembly may cause the leakage of the refrigerant to reduce the performance and guilt of the product system, and may cause environmental damage (e.g., the global greenhouse effect).

Domain Grid Qx 297 Public Love According to the above structure, the first ring and second ring of the upper ring will be sequentially fitted from the end to the outer periphery. The pipe of the ring and the nut is inserted into the inside of the pipe connection part on the other connection side, and then the screw of the nut is screwed with the thread formed on the outer periphery of the pipe connection part to fix the nut. In this way, the stepped portion of the inner periphery of the nut pushes the second ring 'rear' toward the first ring and pushes the rear of the second ring with the front of the second ring. The front inclined surface of the first ring is closely contacted with the inclined surface of the piping connection part ^ Furthermore, the front side of the first ring is reduced inward in the radial direction due to the inclined surface of the piping connection part to fit into the inner pipe, and The first ring and the piping are sealed and fixed to each other. At the same time, the slope of the piping connection part and the front slope of the ring are closely sealed 312563 475047 Printed by the Consumer Consumption Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ____B7 ____ V. Description of the invention (3) Wait until a sealed state is formed. As described above, by sealing between the inclined surface of the piping connection portion and the front inclined surface of the first ring and forming a sealed state between the first ring and the pipe, even if a refrigerant system includes an HFC-based refrigerant, And CO2 (carbon dioxide) natural refrigerants can also reliably prevent leakage of refrigerants to improve the reliability of air conditioners. Furthermore, by preventing leakage of the refrigerant, environmental damage can be avoided, and safety when using a flammable refrigerant can be improved. In addition, this communication piping assembly does not require special tools for piping connection or a welding source of fire 'so it does not cause processing quality differences due to flaring processing and welding. It is simple and easy to tighten the nut Connect the piping securely. In addition, instead of sealing the flared end of the piping and the piping connection, like the flared joint, high-strength materials are used for the first ring and the piping connection. The connection part can repeatedly connect or disconnect the piping without impairing the sealing performance. According to an embodiment of the present invention, a flared rear bevel is formed on the inner periphery of the rear portion of the first ring, and the front of the second ring is abutted to the inside of the rear bevel. According to the above configuration, when connecting the piping to the piping connection, as long as the nut is slowly tightened, the step portion on the inner periphery of the nut can push the back of the second ring toward the first ring, And the front part of the second ring is pressed against the inner side of the rear bevel of the first ring, and then the crotch of the second ring will face the radius because of the rear bevel of the inner periphery of the rear part of the first ring = The inner side is reduced to fit into the inner piping, and the second ring and the pipe are sealed, and at the same time, they can be fixed to each other.
