Vrp® Variable Speed System Vs. Fixed-Speed System - Friedrich VRP12K Service And Parts Manual

INTRODUCTION
VRP® Variable Speed System vs. Fixed-speed System
Low Ambient Heat Pump Performance: Variable speed technology enables VRP units to supply continuous hot air in heat pump mode even
at low outdoor ambient temperatures. This reduces strip heat usage resulting in exceptional savings with VRP units when compared with
Figure 101(Cost Savings)
Precise Temperature & Humidity Control: VRP units not only help keep the air at the preferred temperature, but can more
effectively remove moisture from the air. VRP units run longer cycles at lower pressures, helping to cool the air more evenly.
The combination of variable speed compressor & blower motor and reheat coil in VRP units provide optimal comfort to the
increasing the risk of mold and other airborne problems.
