4.3.13 Booster-/Satellite operation
The VS 300 provides an option for operating the compressor in booster or satellite mode when both control cir
cuits are configured as LP controllers. In satellite and booster operation the two LP circuits are only operated
with one condenser set and therefore with only one common high pressure line.
As the VS 300 is only equipped with two control circuits, an additional controller is required for the
common HP regulation.
S Satellite operation:
In satellite mode, it is operated with one single condenser set by means of a simple combination of the high
pressure lines for the compressor provided for each temperature level which is then fed through one condenser.
The refrigeration points are supplied from one common condensor receiver. During booster operation the refrig
eration points are also supplied by the same condensor receiver. While the suction lines of the NT circuit feed
directly into the main compressor, the refrigerant for the frozen food cases is initially fed through the so called
booster stage.
During satellite operation the compressors for the two temperature zones are controlled independently of each
other via the suction pressure (Standard).
