PURPOSE: A pipe connection structure for an air conditioner is provided to use an aluminum alloy instead of a copper alloy by improving the durability of a pipe connection portion. CONSTITUTION: A pipe connection structure for an air conditioner comprises a first pipe (20), a connection block (30), a second pipe (40), a nipple member (50), and a nut member (60). The first pipe is composed of an aluminum alloy. The connection block is formed in a ring shape and surrounds the circumference of one end of the first pipe. The second pipe is arranged on the same axis as the first pipe. The nipple member is coupled to one end of the second pipe, and male screw parts are formed on the outer surface thereof. The nut member receives the connection block therein and is screwed on the nipple member. |
