Used to Charge air conditioner - as ambient temperature increases gas pressure also increases. So when charging a/c systems, chart is referenced to make sure that proper amount of refrigerant is used

How can the presence of a non-condensable material in a refrigerant cylinder be detected?
comparing the cylinder pressure and the temperature to a pressure-temperature chart.
1996 GMC safari refrigerant pressure?
Depends on ambient temperature need a chart
Ac compressor pressure 1999 stratus?
Depends on ambient temperature - need a chart
What is discharge pressure of Rerigerant134a?
It depends on the ambient condensing temperature. A pressure temperature comparison chart for 134Aa can be found at http://www.csgnetwork.com/r134apresstempconv.html Different refrigerants condensence and evaporate at different temps/pressure
What should the low side pressure be on the 2000 379 peterbuilt day cab?
Depends on temperature and relative humidity. I'd recommend you do a search for an 'R134a pressure/temperature chart'
What should the high low pressure for the AC be when running?
Depends on the ambient temperature - need a chart for details
How do you measure fre-on?
On smaller residential air conditioners the manufacturer publishes a charging chart that has the outside air temperature and the corresponding suction and liquid pressure measured by a refrigeration manifold set, gauges. If the chart is not available, you can estimate by measuring the suction pressure and then using a pressure temperature chart for your refrigerant and trying to maintain a 35 degree to 40 degree temperature at the condensing unit or compressor. The other measurement on larger units is the subcooling measurement, measure the actual liquid line temperature and compare the liquid pressure using a pressure temperature chart and also checking for bubbles in the liquid line sight glass. On larger systems after the subcooling has been checked then the superheat has to be checked and the thermostatic expansion valve adjusted if necessary. To check the superheat, measure the suction pressure, convert to a temperature and then measure the actual suction line temperature. The difference is the superheat, should be 6 to 20 degrees depending on the system.
How determine normal suction pressure in ac unit?
You need a chart which identified the relationship between the ambient air temperature and the pressure, as well as a manifold gauge set.
How do you draw a sublimation curve?
Using a triple point phase diagram or "line graph chart" with temperature and pressure on the outsides then draw the reaction.
What are normal pressure readings on a 1998 ford explorer air conditioning system?
Varies due to ambient temperature - need a chart for accurate readings
Where can one find a temperature conversion chart?
One can find a temperature conversion chart in the following sites; Online Conversion, Temperature table on Temperature World, and Temperature Conversion Table on albireo.
What does a high blood pressure reading on a chart indicate?
High blood pressure reading on a chart indicates that one has a disease. It typically has no symptoms but have life threatening consequences if it doesn't get treated.
