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.
64
Remark
Suction pressure in bar (a) and the corresponding evaporating temperature in °C
Discharge pressure in bar (a) and the corresponding condensation temperature in °C
Oil pressure in bar(a)
Crankcase pressure in bar (a)
Suction temperature in °C
Discharge temperature in °C
Oil temperature in °C
Secondary refrigerant - outlet temperature in °C
Secondary refrigerant - inlet temperature in °C
Motor current in A
Motor speed in rpm
Heat carrier inlet temperature into the heating circuit in °C
Heat carrier outlet temperature from the heating circuit in °C
Intermediate temperature from the heat carrier circuit between condenser and desuperheater in
°C
Intermediate temperature from the heat carrier circuit after subcooler exit in °C
Running hours
Remaining time for auto start delay in sec.
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)
Temperature in oil collection tank in °C
Start to start, remaining time between two starts of the compressor in sec.
Compulsory break timer, remaining time in sec.
External temperature in °C
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).
