6 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. Discharge PRESSURE size system, minor adjustment of controls needed.

7 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. 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).

8 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.

MEDIUM-HIGH TEMPERATURE REFRIGERANT (R-12 TYPE). R-414B: A retrofit blend for R-12 refrigeration and air conditioning General Provisions for Automotive Retrofit Blends: Automotive air systems as well as automotive air conditioning systems. The PRESSURE conditioning retrofitting is governed by Section 609 of the Clean Air and system capacity match R-12 in 40 F to 50 F evaporators, and the Act. The specific provisions of this section which apply to automotive discharge PRESSURE in hot condensers is only 5 to 10 psi higher than R- AC retrofit blends are 1) you can't top off R-12 with a blend, the original 12 (a benefit in automotive AC and warmer refrigeration environments).

10 Charge must be recovered first, 2) new fittings must be installed on the The TEMPERATURE glide runs about 13 F in the evaporator. The addition car which are unique and specific to the blend being used, and 3) when of isobutane to this blend significantly improves mineral oil using blends that contain R-22 the system must have nylon barrier compatibility, particularly for high viscosity oils used in auto AC. hoses installed to prevent leakage. In stationary refrigeration systems running in high ambient R417C: An HFC-based retrofit blend for R-12 and all HCFC retrofit temperatures the use of an automotive blend can relieve problems blends intended for R-12 applications (for example, R-414B). This associated with high discharge pressures, however capacity will suffer second-generation blend contains a hydrocarbon additive and therefore compared to R-12, especially as evaporator temperatures get lower.
