R134a Pressure Gauge Chart This chart details how ambient temperature correlates with the system refrigerant charge pressure, and how it affects high and low side psi readings. refrigeration diagram. Interdynamics MAC-134 EZ Chill Refrigerant Refill ID has been around for a long time. 4) Actual line temperature should = chart temperature above. Just click two times on the graphic on the colored lines and then on the Button Draw Line. – Use filter driers with service pressure rating of at least 600 psig. HNBR is backwards compatible with R-134a and R-12. PROFESSIONAL R134a MANIFOLD GAUGE SET PART #89660 WARNING Wear Safety Goggles Avoid Contact with Refrigerant R134a TEMPERATURE PRESSURE CHART Ambient Temp (˚F) Low Side Gauge High Side Gauge 65˚ 25-35 psi 135-155 psi 70˚ 35-40 psi 145-160 psi 75˚ 35-45 psi 150-170 psi 80˚ 40-50 psi 175-210 psi 85˚ 45-55 psi 225-250 psi 90˚ 45-55 psi 250-270 psi. I can understand having different listings for the High Side because some compressors can pump more volume than others. 03105 m 3 /kg. If you go past that amount (on mine anyways) the compressor starts to cycle from what I imagine is a high pressure cut off. Refer to the R134a pressure temperature relationship chart. A 134a system is similar to a R12 system in that you have a chart listing temperatures and pressures, with 134a running slightly higher. NU-22B, R-22, R-407C, mR-502, R-404A. Pressure-Temperature Chart: ISCEON® MO99™ (R-438A) DuPont™ ISCEON® MO99™ REFRIGERANTS Pressure (psig) R-22 ISCEON® MO99™ Saturated Temperature (°F) Saturated Liquid. R134a has an ozone depletion potential ODP factor of zero 0. 7 kPa) high-side pressure and 24-31 psi (165. Although many of them can withstand stronger gasses, it's generally not recommended. We find the critical values for water from Table A-1 on page 908: Tc = 647. As a example lets say a refrig is very low on freon and the gauge reads 20 inches of vacuum, as freon is added the pressure will increase, first to 10 inches of vacuum,. Pressure Fig. Its measured in PSI (pounds per square inch), not degrees. Its just like how you measure air pressure in your tire. R12 or CFC-12 was damaging and depleting the ozone layer. pdf Free Download Here R134a TEMPERATURE PRESSURE CHART SERVICE & DIAGNOSIS OF R134A SYSTEMS - ariazone. Refrigerant charge quantity for air conditioners & heat pumps: This air conditioning repair article series discusses the the diagnosis and correction of abnormal air conditioner refrigerant line pressures as a means for evaluating the condition of the air conditioner compressor motor, which in turn, is a step in how we evaluate and correct lost or reduced air conditioner cooling capacity. I would think you would use the chart provided as it is a pressure temperature chart. Select a refrigerant to view its boiling point, liquid density and pressure/temperature. CF2FCF3 - 1,1,1,2 tetrafluoroethane, duster gas, R134a, HFC-134a Most gas guns are going to use HFC-134a as a safety gas. R-134a is an HFC refrigerant, which requires polyolester (POE) lubricant to be used in the compressor. The low-side gauge reading at the compressor inlet equals 15 psig or 15 degrees. • Water boils at 250°F if pressure is increased to 15 psig • Water boils at 40°F if pressure is reduced to 0. The test apparatus diameter, length, and material were chosen to simulate the upper-stage cylinder of the com-pressor. For this you need an accurate thermometer that is designed for air conditioning service.
