1 To simmer is to heat to a temperature point just off boiling, generally acknowledged as somewhere around 95 degrees C or something like 195 degrees F.. - 2  This statement is generally true. 3  As noted above, if vapor bubbles are forming in a liquid, at least part of it is at its boiling point.
To Determine Sub-Cooling: 1  Take the high side pressure and convert it to temperature using chart or gauge. 2  Then take the temperature of the liquid line as close to evaporator as possible before the metering device. 3  Take the difference between the above readings.  Sub-Cooling should be around 12-15 degrees.
