A composition of a mixed refrigerant of the present invention, can be used as a natural refrigerant without affecting an ozone layer as a near-azeotrope binary mixed refrigerant with a temperature gradient (TG) not more than 3 ℃ upon evaporation as a refrigerant for a refrigerator or an air conditioner when mixed, with respect to an entire refrigerant composition, at a mixing ratio of 61 to 69 parts by volume of hydrocarbon-based refrigerant gas, propane (C_3H_8), and 31 to 39 parts by volume of propylene (CH_3-CH=CH_2).
본 발명의 혼합냉매의 조성물은 전체 냉매 조성물에 대해, 탄화수소계 냉매 가스인 프로판(C3H8) 61 -69부피부와 프로필렌(CH3-CH=CH2) 31 -39부피부의 혼합비로 배합할 경우, 냉동/공조기용 냉매로서 증발시 온도구배(TG)가 3℃ 이내인 근공비성 2원 혼합냉매로 오존층에 전혀 영향을 미치지 않으면서도 순수 냉매처럼 사용할 수 있는 특징이 있다.
