차세대 냉매의 국내 적용을 위한 안전규격(표준) 및 국내·외 냉동 공조산업 동향의 분석 = Analysis of Safety Standards for the Domestic Application of Next-Generation Refrigerants and Trends in Domestic and Foreign Refrigeration and Air Conditioning Industries

다국어 초록 (Multilingual Abstract)

Korea is the world’s fifth largest producer and accounts for 2.5 of the global air conditioner market share (about KRW 10.2 trillion), but HCFC and HFC refrigerants account for more than 95 of the total refrigerant volume. Small and medium-sized enterprises in Korea lack the technology and experience to switch to eco-friendly alternative refrigerants. They are concerned about their export competitiveness because they are deprived of export opportunities to advanced countries owing to a lack of products. Examples of these are the European F-gas regulations and quotas systems and new refrigerant global warming potential (GWP) limits in California, USA. However, in the domestic market, R-22 refrigerant, which is a refrigerant with the ozone depletion potential (ODP), is still applied, and HFC-410A and HFC-134a, which are refrigerants with high GWP, are mainly applied. From 2017 to 2019, the refrigerant recovery ratio was within 1 of the domestic average annual refrigerant production. To use hydrogen fluorides (HFCs) that are designated as global warming substances in the Kigali Amendment Protocol in 2016, each country is gradually abolishing worldwide refrigerant regulations. Accordingly, domestic and foreign safety standards, refrigerant regulations, and industry trends are reviewed, and problems of the domestic industry and future countermeasures are presented.
