Refrigerant blends offer a compromise between flammability and GWP: for example, a low-GWP but flammable fluid blended with a nonflammable but high-GWP fluid could result in a nonflammable fluid with a moderate value of GWP (order of 500) or a slightly flammable refrigerant with a low GWP (...
ODP of the blend is negligible and the GWP value is lower than theRI34. The binary blend can be used as alternate refrigerant for the both CFC;.I2 and HFC-I14a refrigerating systems. A method forproducing cooling which comprises condensink the refrigerant- and thereafter evaporating said ...
