Pressure Temp Chart R-11, R-12, R-22, R123, R134A, R404A, R-500, R502. Using an HVAC refrigerant pressure temperature chart is necessary to be sure a unit is operating correctly. Below are three free pressure temperature charts that can be used to troubleshoot an HVAC unit. carl ivanelli jr age The refrigerant 'starts' as a low-pressure gas and then transitions into a high-pressure liquid as it absorbs the heat from the indoor space. R22 is then sent to the outside part of the unit, where it releases the heat, cools down, and turns back into a gas. R22 has been used in the air-conditioning industry since the 1930s.Remember, there are two sides to the chart; In °f 1 r22 vapor pressure at sea level r 22 low side pressure 2 r 22 high side pressure 3 0°f 17 8°c' 'the difference between r 22 and r 410a.

How do they make it happen, thanks. Reply: Matthew: The low side pressure when the compressor is running is a feature of the compressor's own pumping power combined with the properties of whatever device is being used to meter refrigerant into the system.
