The GWD of RS44B is lower than R427A, R407A, R407F & R421A. However, this has not been achieved by sacrificing performance since RS44B is similar to R22 in terms of cooling capacity, COP, mass flow, compression ratio & discharge pressure while having a lower discharge temperature. Accordingly, RS44B is …HFO refrigerants, or Hydrofluro-Olefins, are a new class of refrigerants that have a much lessened global warming potential than it’s HCFC alternatives. One example being the 134a alternative, 1234YF, which is 335 times lower on the global warming potential scale and only four times higher than standard carbon dioxide.What Are Normal Operating Pressures For R22? We have a low and high operating pressure for R22. Normal operating pressures for R22 are between 260 psig (at 120°F) and 76 psig (at 45°F). The high-end pressure is measured at condensing temperature and the low-end pressure is measured at evaporator saturation temperature.R422A refrigerant is an HFC mixture that serves as a substitute for R22, R502 and HCFC-containing refrigerant mixtures (R402A, R402B, R409A) in low temperature commercial and industrial refrigeration systems with direct evaporation. It is also used in medium temperature systems. According to the F-gas Regulation, the high GWP value 3134 (> 2500) means that R422A can no longer be used after the ...°F °C R-123-20 -28.9 27.8-15 -26.1 27.4-10 -23.3 26.9-5 -20.6 26.4 0 -17.8 25.9 5 -15.0 25.2 10 -12.2 24.5 15 -9.4 23.8 20 -6.7 22.8 25 -3.9 21.8 30 -1.1 20.7 35 1.7 19.5 40 4.4 18.1 45 7.2 16.6 50 10.0 14.9 55 12.8 13 60 15.6 11.2 65 18.3 8.9 Pressure Temperature ChartsR1234yf, Single Component, HFO.

Ambient Temperature in F Low side Pressure Gauge reading and High side Pressure Gauge reading 65F Ambient temperature: Low side pressure 25-35 psi High side pressure 135-155 psi 70F Ambient temperature: Low side pressure 35-40 psi High ...R422D is an easy-to-use and ozone-friendly HFC refrigerant. It was originally designed to replace R22 in many air conditioning and refrigeration applications. Studies have indicated that R422D’s COP is, on average, 20% lower than of R22 (COP, CoP, CP = coefficient of performance). Thanks to its high GWP value, however, it will be replaced ...Filled with R422D liquid (vapor fill is incorrect) and have been targeting Superheat to determine proper fill. System is a Fixed orifice EVAP coil. Dow Company published an R422D chart to use based upon vapor/suction line pressure on gauge. Chart gives a Dew point temp from the PSI. The Superheat is then calculated using surface temp of the ...R134a Pressure Chart For Refrigerators, Prep Tables & More. In the case of the refrigerant shown above, the room temperature is 71.9°F, and the refrigerant is R-422D. All I had to do was connect the Testo 550 and select R422D and the saturation temperature (shown above the PSI on the right), which is EXACTLY 71.9°F.Gallery of r12 conversion to r134a refrigerant whirlpool - r134a compatibility chart | 4 typical operating conditions for co 2 and r134a download, how to retrofit your ac 134a properly turbo dodge forums, troubleshooting hvac r systems using refrigerant superheat, r134a air conditioning filling chart pdf free download, unknown surprising r152a intarconHFO refrigerants, or Hydrofluro-Olefins, are a new class of refrigerants that have a much lessened global warming potential than it’s HCFC alternatives. One example being the 134a alternative, 1234YF, which is 335 times lower on the global warming potential scale and only four times higher than standard carbon dioxide.R-12 was one of the first ones to go but R-502 wasn't far behind. It's complete phase out occurred in 1995. Originally, R-502 was designed to operate in a low temperature refrigerant applications. It was meant as an alternative to the very popular HCFC known as R-22. R-502 had an overall lower discharge temperature and an improved capacity ...• Temperature glide: R422D has a glide of 4.5 0C which compares with 1.5 0C for R434A. • Refrigerating capacity: R434A has the same capacity as R22. On the other hand, R422D can show a reduction of 5 0C when evaporating at 7 0C, & this lack of capacity increases to 9 0C at -35 0C evap.R22 Pressure-Temperature Chart Saturation Pressure-Temperature Data for R22 (psig)* *Red Italics Indicate Inches of Mercury Below Atmospheric PressureNational Refrigerants, Inc.
