Refrigerant Diagnostic Chart
Refrigerant Diagnostic Chart. The temperature and pressure of the refrigerant have a direct relationship. Automotive air conditioning diagnosis chart low side high side duct temp possible cause low low warm low refrigerant charge high high warm overcharge of.
Our chart below will help you potentially identify the issue you are experiencing. It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges. If we also measure 16 psig at the compressor inlet with the measured temperature of 47°, our superheat in this case would be 31°, calculated by.
Using The Drop Down Menus Below Simply Select Refrigerant Or Temperature To Find The Information You Need.
If oj remains warm, call a serviceman. Remaining hcfc refrigerants can't be produced or imported except for equipment manufactured before jan. The pressure gauges for this refrigerant stays between 22 psi and 57 psi (pounds per square inch).
The Gauges Readings Will Depend On The Ambient Temperature.
It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges. The system should be recovered, vacuumed (min 20 minutes) and charged. Therefore, the superheat is 11°.
Having These Facts Along With The Saturation Point, The Subcool, And The Superheat Numbers For The Refrigerant You Are Working On Are Essential When It.
The ideal freezer temperature is about 0 to 5 degrees (f), and is about 38 degrees (f) for the fridge. This chart details how ambient temperature correlates with the system refrigerant charge pressure, and how it affects high and low side psi readings. We have made this information public solely as a source of information to others who are interested in the servicing of refrigerated containers.

But you have to keep in mind that there are two different sides to this chart. Our chart below will help you potentially identify the issue you are experiencing. Determine cause of the compressor failure b.
The Temperature And Pressure Of The Refrigerant Have A Direct Relationship.
Refrigerator or freezer is not cold enough. Test the door switch / continuity test. R22 and r142b refrigerants can't be produced or imported except for equipment manufactured before jan.
