Prohibition of the use of high global warming potential gases on service or maintenance
From 1 January 2020, the use of fluorinated greenhouse gases, with a global warming potential of 2500 or more, to service or maintain refrigerationequipment with a charge size of 40 tonnes of CO 2 equivalent or more, shall be prohibited.(Article 13-3)
The targets are HFC-23、HFC-125、HFC-143a、R-404a、R-422A、R-507A and so on.
This paragraph shall not apply to military equipment, equipment intended for applications designed to cool products to temperatures below – 50 °C or
refrigeration equipment, alternatives are not available or the other background persuant to Article11-3.
Also it shall not apply to ,until 1 January 2030, reclaimed or recycled fluorinated greenhouse gases used for the maintenance or servicing of existing
refrigeration equipment. (Article 12-6, Article 13-3(b))
