A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators. 85 Psia (G) Saturated evaporative pressure = 24. When repairing refrigerators, air conditioners and other machines that contain refrigerants, service technicians work with pressure temperature, or PT, charts. Before recharging, I googled 'r134a pressure chart', and found the following: At the time, it was 82F in my garage, so I was expecting to end up in the middle of the range (both low- and high-pressure) for the 80F row 45psi for low, and about 190psi for the high side. This is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion. Created Date: 12/8/2010 1:32:38 PM. Condensing temperature or pressure by using the chart of refrigerant. Santech Binary Pressure Switch R12 R134a - Male 38-24 T. For 1,1,1,2-tetrafluoroethane at pressures between 220. Example R-134A Refrigerant Temperature vs Pressure Data: Ambient Temperature in °F 1: R134A Vapor Pressure at Sea Level: R-134A Low Side Pressure 2: R-134A High Side Pressure 3: 65. Cools just fine but the high side is running around 400-450. These two constituents have similar boiling points. Being phased out globally. Subject: Forane 134a Pressure Temperature Chart Keywords: Forane 134a, R-134a, Pressure Temperature Chart, PT Chart, HVAC, refrigeration, air conditioning, refrigerant gas Created Date: 10/4/2012 11:23:04 AM. 9 psia (4060. Vacuumed the system. Pressure Temperature Chart Pressure- Temp Chart R-123a. Fillable and printable R134A Refrigerant Pressure Temperature Chart Template 2020. R-134a - 52% POE Replacement/retrofit for R-22 in DX systems. R-134a can actually cool better than R-12 in a well designed R-134a system as it has better thermoconductive properties, but all the high pressure issues have to be addressed. That converted to evaporation pressure of R134a is 2,25-2,35 Bar absolute. APPENDICES APPENDIX 11 (a) PRESSURE/ENTHALPY CHARTS FOR REFRIGERANTS (a) Tetrafluoroethane (refrigerant 134a) reference state h = 200. Automotive service technicians depend on Freon™ 134a (R-134a) refrigerant, a non-ozone depleting hydrofluorocarbon (HFC) replacement for R-12. 9 Genetron Refrigerants Pressure Temperature Chart 407C 408A 404A HP81 AZ-50 HP80 AZ-20.
