In general, we would just add the atmospheric pressure at sea level (14.7 PSI) to both the suction and discharge pressure and then divide the discharge pressure by the suction. For example, a common compression ratio on an R22 system might look like this: 240 PSIG Discharge + 14.7 PSIA = 254.7 75 PSIG Suction + 14.7 = 89.7 PSIA

Efficiency Ratio (EER) is similar to that of R-22. Discharge pressure is only slightly higher and suction pressure is only slightly lower than R-22, so in most cases, existing system pressure settings can be used. While the existing Thermal Expansion Valve (TEV) sizing and power head can be used with R-438A, the slightly lower suction

The retro˚t procedure for replacing R22 with RS-44s is as follows: 1. If possible collect baseline data before conversion. Suction and discharge pressures can be converted to temperature using an R-22 pressure temperature conversion chart. Once the average evaporating and condensing temperaturesUsing R-22 in an air conditioning application, gauge suction pressure is at 70 PSI and gauge discharge pressure is at 250 PSI. First you need to convert these gauge pressures to PSIA . That means that 15 pounds is added to each gauge pressure. You might recall that our atmospheric pressure is equal to 14.7 pounds pressure at sea level but our ...The pressure-enthalpy chart, as shown in Fig. 2, displays all the pertinent properties for a given refrigerant (in this example R22).

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.Pressure Temperature Chart ...

I've got a 2.5 ton heatpump, @ 90 degrees in heat mode the suction should be @ 74 and the head should be @ 255. Reply. 05-28-2005, 07:33 PM #6. david2641.R22 gauge pressure is 10.9 bar or 158.2 psi. High side pressure typically varies by equipment and metering controls. Low pressure or suction side typically varies by equipment. Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees).Pressure Temperature Chart Pressure Temp Chart-'01 10/31/01 2:54 PM Page 1 Conversions and Formulas CUBIC FEET x 7.480 = GALLONS 2.307 = FEET of WATER PSI x 2.30 = IN HG 27.7 = IN.

The way it seems to me it passes as a high pressure through both service ports, so you will get identical pressures. Hook up to the true suction port for the low side this time and see what you got.
