A structure to connect a refrigerant pipe and an air conditioner having the same, the connecting structure enabling a refrigerant pipe to be easily connected to an indoor unit or an outdoor unit of an air conditioner and including a refrigerant pipe through which refrigerant flows, a socket part connected to one end of the refrigerant pipe, and a coupling nut coupled to an outer circumferential surface of the socket part, wherein, a socket part is provided with a grip-ring allowing the refrigerant pipe to move in a first direction in which the refrigeran...


1. A method of connecting a refrigerant pipe with an assembling jig of an air conditioner having an indoor unit and an outdoor unit, the method comprising: preparing the assembling jig and locating a grip-ring, a washer, at least one O-ring on an outside portion of the assembling jig, the grip-ring configured to prevent the refrigerant pipe from being separated, the washer configured to prevent the O-ring from being damaged, the at least one O-ring configured to prevent refrigerant from leaking;inserting the assembling jig into a refrigerant pipe connect...
