Parameter Description
Discharge Pressure The actual discharge gauge pressure at the compressor flange as
measured by the discharge pressure transducer.
Inverter Temperature Inverter temperature as measured by thermistor mounted under the
IGBT Inverter.
Discharge Temperature The actual discharge temperature at the compressor flange as
measured by the discharge temperature/pressure transducer.
Suction Pressure The actual suction gauge pressure at the compressor flange as
measured by the suction pressure transducer.
Cavity Temperature Temperature of the superheated gas moving past the shaft.
Leaving Temperature Leaving water temperature as measured from the 10K thermistor
connected to the terminals marked “LEAVE” on the Chiller Interface
module.
Total Compression Ratio Ratio of the absolute discharge pressure and the absolute suction
pressure.
Current Draw - Amps 3-phase mains input current.
SCR Temperature Temperature of the SCR heat sink plate.
Anti Start Temperature IGBT Inverter temperature limit at compressor startup.
