5.6 Monitoring and display of process values
The following operating parameters are continuously monitored and displayed by the control:
Designation Remark
Suction pressure Suction pressure in bar (a) and the corresponding evaporating temperature in °C
Discharge pressure Discharge pressure in bar (a) and the corresponding condensation temperature in °C
Oil pressure Oil pressure in bar(a)
Crankcase pressure Crankcase pressure in bar (a)
Suction temperature Suction temperature in °C
Discharge temperature Discharge temperature in °C
Oil temperature Oil temperature in °C
External temperature Secondary refrigerant - outlet temperature in °C
SR inlet temperature Secondary refrigerant - inlet temperature in °C
Motor current Motor current in A
Motor speed Motor speed in rpm
Heating agent inlet temperature Heat carrier inlet temperature into the heating circuit in °C
Heat carrier outlet temperature Heat carrier outlet temperature from the heating circuit in °C
Heat carrier inlet temperature into
desuperheater / condenser Intermediate temperature from the heat carrier circuit between condenser and desuperheater in
°C
Heat carrier outlet temperature of
subcooler Intermediate temperature from the heat carrier circuit after subcooler exit in °C
Operating hours Running hours
Auto start delay Remaining time for auto start delay in sec.
GEA VTrac™ Continuous monitoring of the compressor and motor bearings by means of two sensors in m/s
for early detection of sudden bearing damage
(no normal long-term wear)
Oil return temperature Temperature in oil collection tank in °C
Switch-on blocking time Start to start, remaining time between two starts of the compressor in sec.
Compulsory break Compulsory break timer, remaining time in sec.
Ambient air temperature External temperature in °C
5.7 Sound pressure level
Measuring-surface sound pressure level
Distance to the machine surface: 1 m (A-sound level at free field conditions on
reflecting surface) for heat pumps (1 compressor and 1 drive motor).
Determining the measurement values without secondary sound insulation.
Notice
Measuring-surface sound-pressure level strongly depends on the type of
the heat pump and especially on the type of the drive motor (manufacturer,
type, protection type).
