Abstract

본 발명은 펜타플루오로에탄 20~65%, 1, 1, 1, 2-테트라플루오르에탄 30~75%와 C3탄화수소 5~15%로 비공비성 혼합냉매(Non-Azeotropic Regrigerant Mixtures)와 상기의 비공비성 혼합물을 냉매로 하고 흡입관 열교환기(Suction Line Heat Exchanger)를 사용하는 냉동시스템에 관한 것이다.
본 발명에서 C3탄화수소는 푸로판, 사이클로푸로판 또는 푸로필렌 중에서 선택된 것으로 본 발명의 혼합냉매는 오존파괴 가능성이 전혀 없으며 흡입관 열교환기를 사용하는 냉동기에서 기존 R-22의 대체냉매로서 냉동성능계수 압축기의 냉동체적용량 측면에서 우수한 효과를 나타낸다.
