Refrigeration energy models …R-404A History. R-404A rose to prominence in the late 1990’s with the phasing out of CFC and HCFC refrigerants like R-12 and R-502. There had to be a replacement for the Ozone damaging refrigerants of the past and the successor was the HFC R-404A that we all know of today. 404A’s reign however was short lived.Updated: 20 July 2017 Summary: it is Environmental Protection Agency (EPA) illegal to mix coolant types in a heating, ventilation and air conditioning (HVAC) system. In my (2) R22-based HVAC systems, the low pressure side is 40 and 45 degrees Fahrenheit (F) while the high side is 110 and 115 degrees. Background:USING LINE SIZING CHARTS Basis These line sizing charts are based on a suction pressure drop equivalent to a 2°F change in saturation pressure and liquid line pressure drop of 5 psi. For R-404A Low Temperature 1 psi; for R-404A and R-22 Medium Temperature 2 psi is used. This is the maximum allowable pressure drop for the entire Compressor suction and discharge pressures for R448A relative to R22 are given below. It may be necessary to reset the pressure cutouts to compensate for the different pressures of the replacement refrigerant. This procedure should be done carefully to avoid exceeding the recommended operating limits of the compressor and other system components.Refrigerants - Saturation Pressures vs. Temperatures. Temperature and pressure diagram for constant boiling refrigerants - imperial and SI units. Temperature and pressure chart for refrigerants R22, R410A, R12, R134A, R401A, R409A, R502, R404A, R507A, R408A and R402A. Limit the pressure drop in the discharge line to 6 psid whenever possible to minimize the adverse effect on unit capacity and efficiency. While a pressure drop of as much as 10 psid is usually permissible, note that a 6-psid pressure drop reduces unit capacity by 0.9 percent and efficiency by 3 percent.

As a result, minimal system modifications are anticipated when retrofitting R-22 systems to Freon™ 407C. Original equipment manufacturers should be contacted to determine if discharge pressure controls will need to be adjusted to compensate for the higher discharge pressure.

If possible collect baseline data before conversion. Suction and discharge pressures can be converted to temperature using an R-22 pressure temperature conversion chart. Once the average evaporating and condensing temperaturesCompressor suction and discharge pressures for R448A relative to R22 are given below. It may be necessary to reset the pressure cutouts to compensate for the different pressures of the replacement refrigerant. This procedure should be done carefully to avoid exceeding the recommended operating limits of the compressor and other system components.

R-407C is a zeotropic blend of R-32 (Difluromethane), R-125, and R-134a (Tetrafluoroethane). It is not a drop in replacement on R-22 machines. If you wish to use this product you will need to vacate all of the old R-22 out of the system. This is due to the R-22 systems using mineral oil and this HFC blend using POE oil.R407A Pressure-Temperature Chart Liquid. Vapor: Liquid: Vapor Liquid: Vapor Liquid: Vapor-49; 0; 8.3 ...

R-22 refrigerant is the major refrigerant, or… it was. R-22 was invented by a partnership with General Motors and DuPont back in the 1930's. In the 1950's the use of R-22 exploded and for nearly sixty years it was THE refrigerant to be used in home, office, and commercial air conditioning. Along with air conditioning it was also used in ...R410 A This refrigerant has been prepared by mixing R32 + R125 in equal quantity. It belongs to HFC group of refrigerants.
