Subject: Forane 22 Pressure Temperature Chart Keywords: Forane 22, R-22, Pressure Temperature Chart, PT Chart, HVAC, refrigeration, air conditioning, refrigerant gas Created Date: 10/4/2012 11:22:02 AMOnce the refrigerant has boiled to a vapor then any temperature above and beyond the boiling point is known as the Superheat. In other words, Superheat is any temperature of a gas that is above the boiling point for that liquid. The reason that Superheat is so important to measure is that it can give you a direct indicator as to what is wrong ...

Superheat is a measured value. It is the difference between two temperatures. Superheat is measured as the difference between the actual temperature of the refrigerant vapor and the saturation temperature of the refrigerant at that same point. Superheat on the system's low side can be divided into two types: evaporator …

To calculate superheat, subtract the saturation temperature from the actual temperature. Superheat is important in refrigeration and air conditioning systems to ensure proper cooling and prevent damage to the equipment. Monitoring superheat helps to optimize system performance and efficiency.
