    Sorry to say there is no proper low side pressure. The pressure will change depending upon the expansion device in the evaporator, the outdoor temperature, the temperature coming off the outdoor coil, the humidity level inside the home or structure, and a few other items. This is why they make pressure temperature charts for the different refrigerants, thermometers to test temps,gauge sets to see what is going on inside the unit itself etc. Sorry but there is no simple answer.
