R134a Pressure Chart for Refrigerators, Prep Tables & More. R134a refrigerant is an ethane-based hydrofluorocarbon used in a wide variety of refrigeration equipment, HVAC units and cars. Used as a primary replacement for R12 refrigerant, R134a refrigerant is considered a safe option because it has non-toxic and non-flammable properties and ... GWP - global warming potential - degree to which a greenhouse gas (GHG) traps heat in the atmosphere; all measurements are relative to a similar mass of carbon dioxide (CO²), which is indexed at 1.0. HFCs - hydrofluorocarbons (e.g. R-407C) - do not contain chlorine, but have high GWPs givenlot in my case, though). Here are my stats: Suction line - 63 psi, line temp is 53.5 deg F. Liquid line - 215 psi, line temp is 163 deg F. Ambient air at bottom of condenser is 81 deg. F. (This is after adding about 2 lbs of R22.) If I get it, the subcool is now about 15 deg, and the superheat is. about 60 deg.New Member. Jul 5, 2010, 05:20 AM. Low side pressure reading be on an r22 home unit.

It has two compressors, and i've already recovered the 13 lbs from the first. While starting the 2nd, I was purging my lines and noticed no refrigerant coming out after an unusually long time. This is my liquid line by the way.R-407C exhibits higher pressures than R-22 at normal condensing temperatures. This may require adjusting the high pressure safety controls to operate as intended. 9. Systems that use a low pressure controller to maintain space temperature may need to have the cut in and cut out points changed.The main reasons your compressor will have simultaneously low head pressure and high suction pressure is due to: Bad or leaky compressor valves. Worn compressor piston rings. Leaky oil separator return line. Your compressor valves may become inefficient due to poor sealing from dirt and debris deposits.21 new r22 charging chartAir conditioning r22 pressure rature chart System chargingR22 pressure chart low side.

In heat mode, a dirty outdoor coil can cause a low suction pressure. As an example, Trane includes a pressure curve chart with many heat pump condensing units. Be sure to use the scale all the way to the right that says heat mode.R410a suction pressure may be around 120psi, and R410a head pressure may be anywhere from 225psi to 350psi. Many conditions could apply here, there’s absolutely ‘no’ set point pressure for 410a, r22, or anything else. Educate yourself on whats going on in the heat transfer process.

I had R22 central air system which worked adequatly. The evaporator produced temperature in the range 35-40 degrees. The compressor got flooded during Sandy, and was replaced with the new R407C based unit. No changes were made to evaporator. The low side pressure is around 60 psi, the high side pressure is around 180 psi.If you own a Waterpik and are experiencing low pressure issues, don’t worry – you’re not alone.

The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume.As a ballpark & it depends on a lot of factors, suction should be in the range of 60 to 80 & head should be in the range of 150 to 300. I've got a 2.5 ton heatpump, @ 90 degrees in heat mode the suction should be @ 74 and the head should be @ 255. Reply. 05-28-2005, 07:33 PM #6. david2641.The charts start at the low end (-49°F) and tell you the pressures all the way to the high end (150°F). Example: What is the pressure of 134A freon at 85°F? You just chart the chart (found below) and you will see that at 85°F, the pressure of R134A is 95.2 psig (pounds per square inch gauge).

With clean coils both inside & outside, an inside temperature of 75° with. 50% humidity, I would expect a low side of roughly 70 PSI, and an hi-side pressure of roughly 20-30° above outside ambient temperature. (depending on efficiency of unit) which would correspond to 243-278 PSI.

Depending on your target temperature, you will be very close to, if not below atmospheric on the low side. If you had to put more than half the charge in it, you probably have an obstruction at the metering device.

Compare the super-heat reading to the gauge's psi reading. If the super-heat reading is more than 20 degrees above the P/T chart's reading, then add R-22 until the super-heating reading reaches the optimal range -- between 8- and 18-degree super-heat, depending on the environmental conditions. Many technicians charge the system until ...

With low side blue gauge on the suction line service port, we measured 130 psi pressure that correlates (according to R-410A PT chart) to about 45°F. The clamp-on thermometer shows that the saturated refrigerant temperature is 56°F. Here's how to calculate superheat for this system: Superheat (R-410A) = 56°F - 45°F = 11°F
