LOW-MEDIUM TEMPERATURE REFRIGERANT (R-12 TYPE).

8 R-401A: A retrofit blend for R-12 refrigeration systems. The PRESSURE R-409A: A retrofit blend for R-12 refrigeration systems. The PRESSURE and system capacity match R-12 when the blend is running in a 10 F and system capacity match R-12 when the blend is running in a 10 F. to 20 F evaporator, and there is typically an 8 F TEMPERATURE glide in to 20 F evaporator, and there is typically 13 F TEMPERATURE glide in the the evaporator. Applications: direct expansion refrigeration and air evaporator. Applications: direct expansion refrigeration and air conditioning systems designed for R-12 or R-500; good success in any conditioning systems designed for R-12 or R-500; good success in any size system, minor adjustment of controls needed.

9 Discharge PRESSURE size system, minor adjustment of controls needed. Discharge PRESSURE increases compared to R-12, also slight increase in discharge and TEMPERATURE increases compared to R-12, which may be a problem TEMPERATURE , however the increases are not as severe as some other in very hot ambient conditions. Capacity holds well into lower retrofit blends. There is a drop in capacity at lower temperatures . R- application temperatures (-30 F). R-409A mixes well with mineral oil 152a content, an HFC, hurts the miscibility with mineral oil.

10 It is down to 0 F. As a result it may not be necessary to change oil in recommended to change some of the oil to alkylbenzene unless the systems which do not run colder than 0 F in the evaporator (below 0 F. system is small and running at higher evaporator temperatures . alkylbenzene should replace some mineral oil). R-401B: Similar to R-401A except higher in R-22 content. This blend has higher capacity at lower temperatures (matches R-12 around -30 F), and also provides a closer match to R-500 at air conditioning temperatures . REFRIGERANTS & LUBRICANTS.
