Check all your safety switches including the water flow switch. • Refrigerant charge below manufacturer specification However, for industrial process refrigeration equipment and some federally-owned chillers, additional time may be available. But, being an element in refrigeration, it can also develop some malfunction.

The charts on the back of R134a recharge kits that are available in auto parts stores indicate a car’s low side pressure should be, for instance, 45-55 psi when the outside ambient temp is 85degF.

I’ve seen it multiple times on various refrigerants. Finally, The pressure-temperature chart represents the average pressure-temperature relationship of refrigerant R-134A.

Therefore there is a changing displacement in its operation. I can assure you that when you take your vehicle into a dealership that the pressure and temperature are one of the first things they check when troubleshooting. Being confident with your A/C compressor means it is operating at its optimum capacity. This table represents a pressure temperature chart for R134A.

stream A qualified person with the right tools can identify all the above problems. Low Side and High Side Pressures are Low The gauge/meter installed on the refrigeration component contains two meters/gauge. R-134a is the most common refrigerant found in automobiles today. In this article, let us look at one type of a pressure chart called R134a low side pressure chart. If you are a technician, Consider having it at all times. The condenser fan might not be running due to clogged dirt. To me, those kits’ charts seem incorrect since R134a is almost 58 degF at 55 psi. Need some help? Consider the following. The refrigerant could not be flowing properly. On top of this post we are also working on a comprehensive refrigerant pressure/temperature listing. You can determine the refrigerant pressure at any temperature between −22 and 202 degrees Fahrenheit by reading the value from a pressure temperature chart. R-134a System Pressure Chart. Click the image to the right for purchase options of the UV light to protect your family.

An R134a temperature‐pressure chart shows what the refrigerant temperature should be at a specific pressure.

I have sourced this the best I could but there is always going to be conflicting data. It has been in use since the early 1990’s and now, in 2019, we are beginning to see it’s popularity wane with the rise of the new HFO refrigerant known as R-1234yf. By Alec Johnson May 25, 2019.

Furthermore, R134A is a chemical refrigerant in automotive and domestic use air conditioners.

When interpreting this reading, you compare both the low side and the high side of the chart. Thus, a complete evacuation recovery and recharge is recommended.

R134a pressure chart indicates the pressure-temperature relation to R134a refrigerant. R134a is a refrigerant used in a wide range of home appliances or industrial appliances.

R-134a Refrigerant Pressure Temperature Chart. The meter displays the pressure readings against the temperature readings of the refrigerant.

In a high-temperature refrigeration box, where temperatures typically range from 45 to 60 degrees Fahrenheit, the coil temperature is, typically, between 10 and 20 degrees Fahrenheit colder than the box itself.

The A/C compressor system is not engaged. That being said, there are still millions of cars on the road that use R-134a and there will be continue to be for at least another decade or more.
