초록
오존층 파괴물질에 관한 몬트리얼의정서에 의해 CFC냉매의 규제가 시작된 이후 새로 개발된 CFC대체냉매에 관한 연구현황과 주요 합성방법을 정리하여 기술하였다. 대체냉매로는 HFC-134a와 R-407C, R-410A 등의 HFC계 혼합냉매, 탄화수소, 이산화탄소 등 자연냉매 등이 사용되고 있다. HFC-134a, HFC-125, HFC-143a, HFC-32 등 현재 많이 사용되는 HFC계 대체냉매의 제조방법은 이미 많은 연구가 진행되었고 차세대 냉매의 개발 및 제조연구는 현재도 계속 이루어지고 있다.
Research trend and synthesis methods of alternative of CFC refrigerants which is banned by Montreal protocol that depletes the ozone layer. HFC-134a, HFC mixtures, such as R-407C, R-410A, natural refrigerants, such as hydrocarbons, carbon dioxide etc., were promising replacement of CFC. Many researches on manufacturing methods of HFCs including HFC-134a, HFC-125, HFC-143a, HFC-32, etc. were well carried out. The research on the development and manufacturing techniques of next generation refrigerant is on-going now.
