R22 pressures

8. R-407C exhibits higher pressures than R-22 at normal condensing temperatures. This may require adjusting the high pressure safety controls to operate as intended. 9. Systems that use a low pressure controller to maintain space temperature may need to have the cut in and cut out points changed. With R-407C, the pressure settings must

Before any condensation occurs, the high pressure vapor must first be brought to a saturated condition (de-superheated). FORM 5-200 / Page 3. Enough heat must be transferred from the refrigerant to lower its temperature from 180oF to the saturation temperature of 100oF (point #2A on the chart).rs-44 pressure/temperature comparison values shown: hg" and psig *denotes hg" r-22 rs-44 rs-44 liquid vapor temperature bubble pt. dew pt. c f psig psig psigMar 29, 2017 ... ...

Temp (°F) R-22 R-407C Liquid Pressure R-407C Vapor Pressure R-410A Liquid Pressure R-427A Liquid Pressure R-427A Vapor Pressure R-407A LiquidThe rated pressure for R22 systems was 300 psi. R410A systems are tested for 550psi. If the R22 coil was not rated for R410A, I would be cautious about using it even if the proper R410A metering device is used.

You didn't state the other pressures and temperatures but the SG is a tool to use in determining system conditions. But, we need the other press/temps to assist you further. The SST should be around +25 degrees for a +35 cooler. Could be lower or higher, just depends on how the system was designed. Below we list a dozen causes of high head pressure in an air conditioner or heat pump compressor motor. Of these, debris clogging or malfunctioning TXVs seem to be the most common problems. Air contamination in the refrigerant system. Air flow blocked across the condensing coil. Low condenser airflow will show up as high head pressure, normal ...

Compared to an R22 system, an R410A air conditioner runs at a higher pressure. These systems operate at about 130 pounds per square inch (psi). In AC mode, an R22 evaporator coil will run at about 70 psi. Therefore, newer systems run at nearly double the pressure, assuming they’re … gutter elbowhaircutstory mitsubishi mr slim R22 proper pressures @94 degrees.
