The Uei SSM1 is used to measure superheat and subcooling by direct connections for temperature and pressure. The SSM1 is programmed with the most common four refrigerants, with data from the NIST-Pro refrigeration database for temperature-pressure values. Refrigerant superheat refers to the rise in temperature of vapour after the refrigerant has completely changed from a liquid to a gas. The dew point (temperature at measured pressure where all of the liquid evaporates) is determined by properties of the refrigerant and measuring the pressure. When comparing this to the measured pipe temperature of the return line will determine superheat. The SSM1 will calculate this value directly and update in real time. Use superheat on fixed orifice or capillary systems. Refrigerant subcooling refers to the drop in temperature of liquid refrigerant after it has completely changed from a gas to a liquid. The boiling point (temperature at measured pressure where the liquid stops boiling and starts to further cool) is determined by properties of the refrigerant and measuring pressure. When comparing this to the measured pipe temperature at the exit of the condenser determines subcooling. The SSM1 will calculate this value directly, and update in real time. Use Subcooling on TXV systems, as they are designed to maintain a constant superheat.
