Abstract:
(EN) An air conditioner according to the present embodiment comprises: an outdoor unit which includes a compressor, an outdoor heat exchanger, and a main expansion device, and in which a refrigerant circulates by means of a refrigerant pipe for connecting the compressor, the outdoor heat exchanger, and the main expansion device; and an indoor unit including an indoor heat exchanger, wherein the outdoor unit and the indoor unit are connected by means of a connecting pipe. The air conditioner has a cooling performance of 23-35 kW, a mixed refrigerant containing R32 of 50% or more is used as the refrigerant, and the refrigerant pipe includes a ductile stainless steel pipe having a delta ferrite matrix structure of 1% or less on the basis of a grain size area.
(FR) Un climatiseur selon le présent mode de réalisation comprend: une unité extérieure qui comprend un compresseur, un échangeur de chaleur extérieur et un détendeur principal, et dans lequel un fluide frigorigène circule au moyen d'un tuyau de fluide frigorigène pour relier le compresseur, l'échangeur de chaleur extérieur et le détendeur principal; et une unité intérieure comprenant un échangeur de chaleur intérieur, l'unité extérieure et l'unité intérieure étant reliées au moyen d'un tuyau de raccordement. Le climatiseur possède une performance de refroidissement de 23 à 85 kW, un fluide frigorigène mélangé contenant du R32 à 50 % ou plus est utilisé comme fluide frigorigène, et le tuyau de fluide frigorigène intègre un tuyau en acier inoxydable ductile ayant une structure de matrice en ferrite delta inférieure ou égale à 1 % sur la base d'une surfacee de taille de grain.
(KO) 본 실시예에 따른 공기 조화기는, 압축기와, 실외 열교환기 및 메인 팽창장치를 포함하고, 상기 압축기, 상기 실외 열교환기 및 상기 메인 팽창장치를 연결하는 냉매배관에 의하여 냉매가 순환되는 실외기와, 실내 열교환기를 포함하는 실내기 및 상기 실외기와 상기 실내기는 연결배관에 의하여 연결되는 공기 조화기로서, 상기 공기 조화기의 냉동능력은 23kW 이상 35kW 이하를 가지고, 상기 냉매로는 R32가 50% 이상 함유된 혼합냉매가 사용되며, 상기 냉매배관에는, 입도면적을 기준으로 1% 이하의 델타 페라이트 기지조직을 가지는 연성 스테인리스 강관이 포함된다.
