Let's say a system has 45 psi suction pressure (converts to 22 ° F) and 68 ° F suction line temperature, the superheat is 46 ° F (68 minus 22). This indicates low refrigerant in the evaporator. However, before adding refrigerant, check the subcooling to be sure the problem isn't ...Pressure- Temp Chart Physical Properties of Refrigerants R22 Environmental Classification Molecular Weight Boiling Point (1atm,°F) Critical Pressure (psia) Critical Temperature (°F) Critical Density(lb./ft^ 3) Liquid Density (20 °F,lb./ft^3) Vapor Density (bp,lb./ft^ 3) Heat of Vaporization(bp,BTU/lb.) Specific Head Liquid( 20 °F, BTU/lb. °F)At 318.5 PSI, the saturated temperature is 100°F. If you measure 118 PSI on the low-pressure side of the system, then you know that the saturated temperature of the refrigerant flowing through the middle of the evaporator coil is at 40°F. This is a useful number when combined with the temperature of the tubing near the pressure port.On a 80 degree day you should be seeing at least 70-75 suction and 240-260 high side. ... maybe used 3 times.

I got a pressure reading of 90 psi on the low side and 190 psi on the high side.The low-side should be near 30 PSI at 90 degrees Fahrenheit or less. Pressure that is too much lower or higher shows there is a problem. On a properly working system, high - side pressure will be about twice the ambient temperature, plus 50 PSI.Connect R22 manifold gauge middle hose onto R22 refrigerant container. Flip R22 container upright and open the valve. Watch left and right gauges to see when pressure equalizes. Left-hand gauge should read below 60psi. Open left-hand gauge handle briefly to drop pressure. Allow system to run for 3-5 minutes.Most technicians in the HVAC field know the normal range of operation for the low-pressure side of an air conditioning system.

You can see that this R410A pressure chart includes high and low side pressures at temperatures ranging from -60 °F to 155 °F. Higher temperature equates to higher pressure. Here are 4 examples of how you can use this chart:R-407C is a zeotropic blend of R-32 (Difluromethane), R-125, and R-134a (Tetrafluoroethane). It is not a drop in replacement on R-22 machines. If you wish to use this product you will need to vacate all of the old R-22 out of the system. This is due to the R-22 systems using mineral oil and this HFC blend using POE oil.R407c is an HFC refrigerant that will replace the R22 refrigerant, as per Montreal Protocol. It is a mixture of R32 (23%), R125 (25%), and R134a (52%) that has a boiling point of -46.84°F.

Total Superheat Method (Fixed Orifice / Piston / Capillary Tube / Non-TXV) Temperature must be above 55°F outdoors and above 70°F indoors with a indoor wet-bulb temperature above 50°F The evaporator coil cannot operate below freezing or an overcharge and possible compressor damage could result.The high side pressure, in contrast, refers to the refrigerant pressure in the discharge line. This is basically the pressure after the compressor. Even though the ideal pressure range for an R-401A air conditioner falls in the range of 110-140, its low side pressure should not be less than 100 psi, nor should it be more than 160 psi.
