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. 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. There are many lower-GWP refrigerants available. ⚫ Refrigerant: R32 is becoming more prevalent in various countries. 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. 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 … 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。 Easy to recover and reuse, R-32 is the perfect solution for attaining the new European CO 2 emission targets. 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. 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. R32 is used for small air-cooled scroll-type compressors. It is because of these reasons that R-32 offers the lowest total emissions and best overall life-cycle climate performance. 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. 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. Daikin Creard R-407H is a new, cost-effective, high efficiency, lower GWP refrigerant gas for refrigeration contractors and distributors. Daikin launched the world's first residential-use air conditioner that uses R-32 technology to lower environmental impact. Also R-32 is a single component refrigerant, which makes it easy to recycle. 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. Daikin is a pioneer in launching heat pumps equipped with R-32. It could reduce the charging volume by 30% compared to R-410A. R32 is a chlorine-free, ozone-safe fluorocarbon whose boiling point is -52°C. It is also the main supplier of R407H, a lower GWP replacement for R40A in existing refrigeration systems. 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. This, together with national policies taxing CO 2 equivalence, has led to a growing demand for lower-GWP alternatives. Better than R410A and R22. WHAT IS R32 R-32 has zero Ozone Depletion Potential (ODP) and Modified Global. 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 (Source: Daikin Industries Independent Survey from … Ideal for Warming Potential (GWP) of 472, compared to R-410A’s Modified GWP of 2,027.
