R134a diagnostic pressure chart

Jan 21, 2013 · A pressure drop through the distributor assembly on R-134a may be in the vicinity of 25 psi. This means that with the use of a refrigerant distributor, a measured temperature between the outlet of the thermostatic expansion valve and the inlet of the distributor of approximately 50°F would not be abnormal.

Then look at the pressure temperature chart of the refrigerant and there is your answer. Let’s do an example. A walk-in fridge or reach-in fridge with R22 has a desired box temp is 38*F. What is 38*F on a P/T Chart? Around 63 PSI. But we don’t want 38*F, we want 28*F. So what’s 28*F? Around 49-50 PSI. So the suction side should be around ...Most automotive refrigerant is today is R134A. Newer vehicles may use R1234YF and this will become more common in the future. Diagnosis of R1234YF systems is different and not covered in this article. Older systems use R12 and while the pressure varies slightly from R134A, the principles are the same. A refrigerant gauge set will have two gauges.

Never use compressed air to leak test or pressure test an R-134a system or R-134a service equipment. Under certain conditions, pressurized mixtures of R-134a and air can be combustible. Always follow the proper procedures to prevent any safety hazards. In addition, shop air injects moisture into the system, and a pressure surge could damage ...Automotive AC Pressure Chart for Air Conditioning Systems with R134a: FOR AUTO AIR CONDITIONING R134a SYSTEMS: At IDLE - Condenser inlet temp 170 to 180, Condenser Outlet temp 135 to 150 (usually a 30 to 40 degree drop in temperature across the Condenser), Evaporator Outlet temp 45 to 55, Compressor Suction temp 60 to 70 …

An R12 to R134a refrigerant conversion chart is a tool used to properly recharge or convert a vehicle air conditioning system based on the refrigerant type and operating conditions. R12 and R134a are the most common types of refrigerant gas...Step 1: Turn the engine off and install the gauge set. Step 2: Restart the engine and turn on the air conditioning. Step 3: Observe the pressure readings. Though every air conditioning system will vary, you want to see the high side pressure around 20 psi and the low side around 40 psi.R134a Pressure Enthalpy Chart. Scroll down to find download buttons for pressure enthalpy charts in either Metric or Imperial Units. Downloads as a PDF. These charts were provided courtesy of Danfoss, using their FREE CoolSelector 2 software.• If a repair is performed on an R134a compressor or system, evacuate the system for at least 30 minutes before recharging to ensure the removal of moisture which may have been absorbed by the PAG oil in the compressor and system. 4.2 Table of Saturation Temperatures and Pressures (R-134a) Temp. (F) Pressure (psig) Temp. (F) Pressure …Step 1. Connect the high-pressure part of your unit’s cooling line with a red port on a gauge. Remember, the red gauge and port are always high-pressure gauges. Attach the red hose (code-approved) to the high-pressure port using flare-fittings on your cooling unit. Make sure the red hose can handle high pressure.

3. Compare the pressure readings to the pressure-temperature chart below. R-134a Static Temperature pressure chart. WARNING: Ambient temp is the temperature at the vehicle under the hood, NOT THE WEATHER SERVICE. R-1234yf Static Temperature Pressure Chart. What static pressures actually means.Before the vehicle is started, the static system pressure should be read. Pressure values should be very nearly equal on both LP and HP gauges. The actual static pressure will depend on the ambient temperature. To ensure it is on the right level, refer to a static pressures table applicable for R134A refrigerant (N.B. not shown on this poster). ….
