Daikin is one of the world's largest commercial air conditioner and refrigeration equipment manufacturer. Daikin manufactures not only air conditioners but also develops new refrigerants for use. The first residential air conditioner powered by R-32 refrigerant was introduced by Daikin in November 2012, in Japan. When compared to R-22 and R-410A, R-32 transfers heat at a much higher rate, can reduce energy consumption by up to 10%. Hence it has a significantly lower impact on the environment. It also reduces global warming and its carbon footprint. They have just 1/3 of the dangerous Global Warming Potential (GWP) of R-410A and an ozone exhaustion of 0.
