Your blood pressure readings are useful indicators of your cardiovascular system’s overall health. Low, high and normal blood pressure readings help your doctor make the right deci...Suction. Gasses or liquids that move along a pressure gradient can exert forces on objects. Objects can only be pushed by gases or liquids. The correct terminology used depends on whether they are pushed from a pressurized zone towards ambient pressure (blown out) or from ambient pressure towards a low pressure zone (sucked in).

Take the suction pressure and use the pressure/temperature chart to convert it to temperature. Let’s say the suction pressure is 60(Psi) which converts to 34F. And assuming that the suction line temperature is 44F. Then to get superheat we just get the difference between the two temperature readings. In this case, we have 10F of superheat.Problem, Low suction pressure and superheat. Icing up. 15 year old RUUD split sys. Old comp. locked up, not burnt.
