Special measures for Field 1 as well as Field 2
Fig.10:
The measures required to prevent liquid refrigerant entering the compressor,
depend upon the heat pump evaporating temperature (To) and the ambient
(machine room) temperature close to the compressor.
(Area 3= high risk, Area 2 = medium risk and Area 1 = low risk)
For this graph not only design conditions have to be observed, every possible
condition has to be taken into account. The highest risk possible during standstill
or operation should then be considered.
Area 1 (low risk)
Machine room temperature always more than 5K higher than the heat pump eva-
porating temperature

Nota!
The bypass valve, used for unloaded start is only active during accele-
ration with a maximum of 10 sec. after start. During standstill or run-
ning it is not allowed to activate the bypass valve.
