Annex 54 Country Report: Japan
The report provides an in-depth analysis of the life cycle climate performance (LCCP) and risk evaluations for heat pump systems using low-global warming potential (GWP) refrigerants in Japan. This study aims to identify suitable refrigerants, assess their environmental impact, and evaluate safety measures to mitigate associated risks. The LCCP evaluation adheres to guidelines from the International Institute of Refrigeration (IIR) and examines refrigerants such as R410A, R32, R454C, R290, and R22, chosen for their performance characteristics and potential as next- generation refrigerants.
