Title
(EN) AIR CONDITIONER
(FR) CLIMATISEUR
(KO) 공기 조화기
Abstract
(EN) The present invention relates to an air conditioner. The air conditioner according to the present embodiment has a refrigeration capacity of 2kW to 7kW, inclusive, and uses R410a as a refrigerant circulating therein, and since a refrigerant pipe therein includes a ductile stainless steel pipe made of a material containing, at least, chrome (Cr), nickel (Ni), manganese (Mn) and copper (Cu), the refrigerant pipe can maintain strength and hardness as good as or better than those of a copper pipe, while also maintaining good processability.
(FR) La présente invention concerne un climatiseur. Le climatiseur selon le présent mode de réalisation a une capacité de réfrigération compris entre 2 kW à 7 kW, et utilise le R410a en tant que réfrigérant circulant à l'intérieur de celui-ci. Ce climatiseur est caractérisé en ce qu'un tuyau de réfrigérant à son intérieur comprennes un tuyau en acier inoxydable ductile fait d'un matériau contenant, au moins, du chrome (Cr), du nickel (Ni), du manganèse (Mn) et du cuivre (Cu). Ce tuyau de réfrigérant peut maintenir une résistance et une dureté aussi bonnes que celles d'un tuyau de cuivre, tout en conservant également une bonne aptitude au traitement.
(KO) 본 발명은 공기 조화기에 관한 것이다. 본 실시예에 따른 공기 조화기의 냉동능력은 2kW 이상 7kW 이하를 가지고, 공기 조화기를 순환하는 냉매로는 R410a가 사용되며, 냉매 배관에는, 적어도 크롬(Cr), 니켈(Ni) 및 망간(Mn)과 함께, 구리(Cu)를 가지는 물질로 구성되는 연성 스테인리스 강관이 포함되므로, 냉매배관의 강도 및 경도를 동 배관 이상으로 유지하면서, 가공성이 좋게 유지할 수 있다는 이점이 있다.
