本論文は、CFC・HCFC・HFCからHFO・炭化水素・アンモニア・CO2といった低GWP冷媒への転換に関するレビューである。モントリオール議定書キガリ修正の規制動向を踏まえ、各冷媒の熱力学的特性・安全性・環境影響とVCRシステムのCOP・エネルギー効率を比較する。自然冷媒やHFO混合冷媒はGWPを大幅に削減しつつ競争力のある性能を示すが、可燃性・毒性・システム再設計が普及の障壁となる。
English
This review examines the shift from CFCs, HCFCs, and HFCs to low-GWP refrigerants such as HFOs, hydrocarbons, ammonia, and CO2 in vapour compression refrigeration. It compares thermodynamic, safety, and environmental properties alongside COP and energy efficiency, driven by the Kigali Amendment's phase-down. Natural refrigerants and HFO blends cut GWP substantially with competitive performance, though flammability, toxicity, and redesign needs remain barriers.

📄 Abstract（原文）
The refrigeration and air-conditioning sector play a central role in food preservation, thermal comfort, healthcare, and industrial processing, but the working fluids historically used in vapour compression refrigeration (VCR) systems — chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs) — contribute significantly to ozone depletion and global warming. International agreements such as the Montreal Protocol and its Kigali Amendment have accelerated the phase-down of high Global Warming Potential (GWP) refrigerants, driving research toward low-GWP alternatives including hydrofluoroolefins (HFOs), hydrocarbons (HC), ammonia (R717), and carbon dioxide (R744). This paper reviews the thermodynamic, safety, and environmental characteristics of conventional and eco-friendly refrigerants, compares their coefficient of performance (COP) and energy efficiency in VCR systems, and discusses the technical, safety, and regulatory challenges associated with their adoption. The review finds that natural refrigerants and HFO blends offer substantial reductions in GWP with competitive or improved energy performance, though flammability, toxicity, and system-redesign requirements remain key barriers to widespread implementation. The paper concludes with recommendations for future research directions, including refrigerant blend optimisation, safety engineering for mildly flammable fluids, and integration of renewable energy with next-generation refrigeration systems.
