Position of bypass ball valves
ER label
Attention: It is NOT allowed to use the ball valves at an in-between position!
BV1 must have a higher opening temperature (set point) than BV2 in order to prevent the heat from being
dissipated in the compressor oil cooler (Co) rather than in the oil/water heat exchanger (HE) when using
the compression heat as source for energy recovery.
