We would like to show you a description here but the site won’t allow us.An R12 system should have a minimum of 60 psi to avoid freezing. That’s with a Fahrenheit of 70–74 degrees Fahrenheit as the ambient temperature. Low and high side pressures should increase as the ambient temperature rises. The high-side pressure on a fully operating system will be around twice the ambient temperature + 50 PSI.

On my Yellow jacket manifold a/c gauges the low side at ithe condenser r22 is high @ about 110 while the high side ...Suction Pressure/Low Side. Suction pressure tells us several things. The first thing it tells us is what the boiling temperature of the refrigerant in the evaporator is. If the suction pressure is below 32° saturation temperature, the evaporator coil will eventually freeze.

Source: hvac-talk.com > * beginning january 1, 2020: I ended up with a low side pressure of 70 psi and a high side of like almost 270 psi on the high side ...The head (high side) pressure depends on the TEMPERATURE at which the refrigerant (R-22) condenses in the condenser (outdoor coil). Add 15 to 25 degrees F to the outdoor temperature (say 90+15=105 and 90+ 25=115) and look at the TEMPERATURE information for R-22 on the gauge (green ring of numbers).R-22 Replacements Pressure-Temperature Guide Key: Green (in of Hg) = Vacuum Black (psig) = Saturated Vapor (calculate Superheat) Bold (psig) = Saturated Liquid (calculate Subcooling)The pressure increases when more of those molecules zoom around the closed space. At some point, the vessel's pressure will exceed the liquid's vapor pressure. Boiling will stop when this happens. When boiling stops within a closed system, the temperature and pressure stop increasing. The refrigerant will reach equilibrium.An R22 system has the following readings: 65 suction pressure 236 high side pressure suction line temp is 48 degrees liquid line is 90 degrees Calculate the superheat. evaporator. The part of an air conditioning system that changes the refrigerant from a low pressure liquid to a low pressure gas is the. 23.

T/P chart says pressure is say R22 is 168 @ 90 degrees. How can the OP even have numbers as low as was reported? I would think the unit would have to be nearly empty of charge to have numbers this low.... as I understand it (studying for my 608 T2 exam, BTW ), if I have even a few ounces of R22 in a container at 90F, the pressure should be 168 ...

In the 1950’s the use of R-22 exploded and for nearly sixty years it was THE refrigerant to be used in home, office, and commercial air conditioning. Along with air conditioning it was also used in ... In this case, this pressure (46 psig) will correspond to a temperature of 23 degrees, which is 15 degrees cooler than the lowest desired box temperature of 38 degrees. If the pressure control has a high event (cut-in) and a differential setting, the cut-in will be set at 68 psig and the differential will be set at 22 psig (68 psig - 46 psig).R134a refrigerant exhibits a pressure-temperature relationship as follows: at -30°C (-22°F), it’s around 92 kPa (13.4 psig), while at 60°C (140°F), it reaches about 1148.2 kPa (166.4 psig).

For example, if the condensing temperature is 100°F and the ambient is 80°F, the CTOA would be 20°F (100°F - 80°F).

If the refrigerant picks up 10 degrees of superheat in the evaporator, you'll have about a 50-degree suction line at the evaporator coil outlet (+/- 5 degrees or so). Then, when you measure the suction line before the compressor, the temperature can increase about 3-5 degrees more. Overall, you'll want your temperature to be below 65 degrees at ...Low-Pressure Suction Side. The low-pressure side, when connected to the gauge, should read less than 100 psi.
