R409A Mixed Refrigerant Gases For Air conditioning , Blend Mixing
Disposable Cylinder Packing R409A Mixed Refrigerant Gases For Air
R409A is a zeotropic HCFC blend of R-22, R-124, and R-142b. Its
boiling point is -35.3 °C. Its critical temperatiure is 109.4 °C.
HCFC refrigerant R409A is a blend of R-22, R-142b, and R-124, intended for retrofitting R-12
refrigeration systems. The pressure and system capacity match R-12
when the blend is running in a 10F to 20F evaporator, and there is
typically 13F temperature glide in the evaporator.
Direct expansion refrigeration and air conditioning systems
designed for R-12 or R-500; good success in any size system, minor
adjustment of controls needed. Discharge pressure and temperature
increases compared to R-12, which may be a problem in very hot
ambient conditions. Capacity holds well into lower application
temperatures (-30F). R-409A mixes well with mineral oil down to 0F.
As a result it may not be necessary to change oil in systems which
do not run colder than 0F in the evaporator (below that
alkylbenzene should replace some mineral oil).
