R-407C consists of a mixture of HFC blends – in essence, 52% of R134A, 25% of R-125, and 23% of R-32. Hence, it has zero ozone depleting potential since it doesn’t contain chlorine in its components. On top of that, it has a lower global warming potential than R-410A. 407C has a GWP of 1774, while 410A is at 2088.The piston/fixed orifice type system primarily uses the superheat method, and the TXV/EEV primarily uses the subcooling method. When setting a charge, it is always preferable to set the charge in cool mode. ...
