R32 - for our environment! In the last two decades important progress has been made towards the usage of more environmentally friendly refrigerants. Our behavior and attitude concerning the environment has to change and become more responsible. Governments worldwide implement new regulations to limit emissions which cause harm to the environment. The main goal of the new F-Gas Regulation is to incrementally limit the sales volume of hydrochlorofluorocarbons (HCFCs). Until 2030 the CO2 emissions should be decreased by 79 % of today’s equivalent sales volume. Why is R32 required? The Main Pillars of the new EU F-Gas Regulation are to reduce emissions and to move towards lower GWP solutions. The nowadays widespread refrigerant R410A does not meet these requirements, having a GWP of 2,088. R32 has a GWP of 675 and meets legislation criteria.
How efficient is R32? R32 has a similar working pressure to R410A which is around 12 to 26 bar, however R32 has better capability to exchange heat-load than R410A and delivers higher capacity than R410A making the systems more efficient. Is R32 a popular refrigerant? TOSHIBA has been producing R32 units for use in the Japanese market since 2014 for both Residential and Light Commercial. More than 220,000 residential units have been installed without any incidents. For Light Commercial there are approximately 5,000 impeccable installed units. Across all manufacturers there are more than 5 million R32 units installed only in Japan. Other countries such as India and China rely on R32 split residential systems as well.
Reduction of refrigerant used due to usage of R32 R32 has a lower GWP than R410A and uses 30% less refrigerant charge to produce an equal load capacity. As a result the total CO2 emission can be reduced by around 77%. Capacity code
