Ideal for R32 is a component of R410a, a blend refrigerant widely used in developed coun-tries as a main alternative to HCfC-22, an ozone depleting refrigerant. Daikin has found that in comparison to R-410A, R-32 has a drastically lower GWP and could reduce refrigerant charge in certain equipment by up to 40 percent. R32 is a chlorine-free, ozone-safe fluorocarbon whose boiling point is -52°C. It is because of these reasons that R-32 offers the lowest total emissions and best overall life-cycle climate performance. Also R-32 is a single component refrigerant, which makes it easy to recycle. This, together with national policies taxing CO 2 equivalence, has led to a growing demand for lower-GWP alternatives. Daikin was the pioneer in introducing R32 as a lower GWP replacement for R410A, a move which has since been followed by most major air conditioning manufacturers. It could reduce the charging volume by 30% compared to R-410A. Warming Potential (GWP) of 472, compared to R-410A’s Modified GWP of 2,027. It is also the main supplier of R407H, a lower GWP replacement for R40A in existing refrigeration systems. Daikin launched the world's first residential-use air conditioner that uses R-32 technology to lower environmental impact. その度合いを数値化したものが 地球温暖化係数（gwp）100年値 で、数値が大きいほど 温暖化への影響は大きくなります。 オゾン層破壊係数がゼロで、さらに地球温暖化係数が低い新冷媒、それがr32（hfc）です。 ⚫ Refrigerant: R32 is becoming more prevalent in various countries. Daikin is a pioneer in launching heat pumps equipped with R-32. Relying on proven traditional chemistry, it is built as a replacement for R-404A, R-507A, R-407A/F, R-22 and other high GWP refrigerant blends in medium temperature and low temperature refrigeration applications. R32 is used for small air-cooled scroll-type compressors. R-32 has zero ODP (Ozone Depletion Potential) and its GWP (Global Warming Potential) is 675, which is lower than the GWP of currently used R-410A or R-22. (Source: Daikin Industries Independent Survey from … Efficiency: “Test data in Daikin’s labs of inverter-driven compressors for rooftop units and water-cooled chillers found that full-load and partial-load efficiency rating metrics can be improved by up to 12% using R-32 instead of R-410A,” advised Phil Johnston, PEng, GM, Low GWP Program Leader at Daikin … Daikin Creard R-407H is a new, cost-effective, high efficiency, lower GWP refrigerant gas for refrigeration contractors and distributors. R-32 has zero Ozone Depletion Potential (ODP) and Modified Global. Better than R410A and R22. Easy to recover and reuse, R-32 is the perfect solution for attaining the new European CO 2 emission targets. R-32 related CO 2 emissions decrease by 76% thanks to the lower GWP and the charging volume reduction. But R410a has a high global Warming Potential (hereafter, gWP) of 2088, so a new refrigerant With Daikin's commitment to releasing more products with low GWP refrigerant, R32, Daikin is pleased to announce the launch of the R32 SkyAir Compact Cassette. With a lower Global Warming Potential (GWP), the R-32 is equivalent in power to standard refrigerants, but achieves higher energy efficiency and lower CO 2 emissions. WHAT IS R32 R32 is a popular choice, due to its availability, performance and efficiency, but R454B and R452B also offer convenience and, potentially, low system qualification costs. While R32 VRF/VRV systems are being developed – Daikin has already launched a high-capacity R32 VRV in Japan, earlier this year – units available for every application will still take some time. There are many lower-GWP refrigerants available.
