INTRODUCTION
Part Load Performance
Exceptional Efciencies with VRP®: Partial load conditions prevail for the majority of the time. VRP’s Precision Inverter®
compressor can operate down to 40% of rated capacity or up to 120% matching the unit’s output to the actual demand of
the space and, therefore, only consumes the energy that is required. Because of this ability to modulate the capacity, VRP
delivers signicantly higher efciencies than a xed–speed unit resulting in huge savings in operational costs. Example of
variable speed efciency below.
