Summary
In Japan, from 2011 to 2016, risk assessment of each type of equipment using A2L refrigerants was carried out and JRAIA standards which prescribed safe operating method were created, resulting in the relaxation of law was realized. In order to respond to demand in recent years to further lower GWP, risk assessment of builtin refrigerated display cabinet using A3 refrigerants was carried out. CFD analyses on refrigerant leakage from inside or outside the refrigerated space of each refrigerated display cabinet was carried out, the flammable volume was calculated, the ignition sources were investigated, and the ignition probability was calculated. Risk assessments were carried out at each stage of transportation, storage, installation, usage, service, and disposal. In this paper, the contents of the study and safe operating method created as a result are summarized.
