INTRODUCTION
The Friedrich VRP® is a variable capacity system that utilizes Precision Inverter® technology to provide optimal space
conditions.
While each VRP unit has a nominal capacity of 7,000, 12,000, 24,000, or 36,000 Btus, every unit has the ability to adjust Btu
output based on the actual room load. This equates to:
• Greater in-room dehumidication from longer compressor run time
• Lower energy costs by consuming less power
• Greater occupant comfort due to smaller swings in room temperature and humidity
The VRP accomplishes this by constantly monitoring various system and environmental inputs to vary the output of the unit.
The ability to vary compressor and blower speeds and the use of reheat coil enables the VRP to provide optimal comfort.
With up to 20.0 SEER and 10.0 HSPF, the VRP provides a highly efcient solution. Further, the Precision Inverter technology
allows the heat pump to operate at ambient conditions as low as 0˚F reducing the use of strip heat. This results in signicant
savings in operational costs.
An optional integrated FreshAireTM system delivers conditioned fresh air into the space. The fresh air is ltered through
a MERV 8 lter and is then conditioned through the unit’s primary DX coils backed by a reheat coil that augments the
unit’s dehumidication capability. This integrated fresh air solution provides the ability to potentially downsize or eliminate
additional make up air and humidity control equipment.
Friedrich’s wall controller is the main interface between conditioned space and the unit. The controller has seven back‑lit
segment displays that indicate the system mode (cool, heat, fan only), fan speed (low, high or auto), set point (°F or °C) or
alternatively room temperature (°F or °C).
The controller has an integrated temperature and humidity sensor that sends room status to the main control unit (MCU) to
determine operating modes and speeds of various components.
The wall controller also contains a motion sensor that wakes the wall controller from a sleep mode when not in use. This
energy saving feature eliminates annoying glow from the controller and the need to turn on lights at night to operate it.
The unitary packaged design means easier installation or replacement. Because the VRP is a packaged unit, it is installed
as a completely assembled refrigeration system. Unlike VRF or chilled water systems that require on‑site wiring, piping and
sealing of individual components, VRP units are assembled, charged and run tested under strict quality control guidelines
in Friedrich’s North American factory. Additionally, there is no need to locate the cooling tower or condensing units on the
ground or rooftops where green spaces can exist instead.
In sum, The Friedrich VRP offers a signicant value to all parties involved in the design and construction of a new building.
Because of the simpler and more straightforward nature of the packaged design, and the ability t o potentially downsize or
eliminate additional make up air and humidity control equipment, the VRP reduces much of the headache and complexity
facing the design engineer. Because the VRP is easy to install, with no complicated oor-to-oor piping and wiring involved,
the contractor can be condent of a high-quality installation and get on and off the job more quickly. And nally, the owner
gets the efciency and performance of larger, more complex and costly equipment, with a lower overall installed cost; and
he/she virtually eliminates the potential safety and service issues associated with systems that rely on thousands of feet of
refrigerant or water piping running throughout the building, including occupied spaces.

INTRODUCTION
Part Load Performance
Exceptional Efciencies 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 signicantly higher efciencies than a xed–speed unit resulting in huge savings in operational costs. Example of
variable speed efciency below.

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 stripheat usage resulting in exceptional savings with VRP units when compared with

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.

FreshAire is a dedicated fresh air system that brings in up to 70 CFM of outdoor air into the VRP® unit. The FreshAire system
uses one fan (up to 35 CFM) or two fans (up to 70 CFM) (depending on outdoor air CFM volume requirements) to bring in fresh
outside air into the the unit. The outdoor air passes through dedicated 6”x 6”x 1” MERV 8 lters that are easily replaceable
from the front of the unit.
This outdoor air is mixed with the return air inside the unit prior to the main evaporator coils, reheat coil and heater. Because
of the variable speed of both the compressor and evaporator fan, the VRP can increase or decrease the unit’s capacity to cool,
heat or dehumidify the total supply air. The system uses a proprietary algorithm to measure the dew point of the leaving air.
As the system nears the room setpoint, the system will throttle back both the compressor and the supply air volume in order
to maximize the dwell time on the indoor coil to maximize dehumidication.
(Single speed systems cycle on and off, providing less dehumidication capacity and run time as well as encounter
condensate re‑evaporation when cycled off.)

INTRODUCTION
Reheat Coil - Augments VRP’s Dehumidication Capability
Temperature differences are not the only source of discomfort in a living space. Humidity also plays a big role — especially
in climates that tend to be both hot and humid. The air conditioning industry’s focus on humidity issues has elevated the
importance of dehumidication. Air conditioning units operate in environments with varying indoor humidity levels. Therefore,
the system should be able to adequately respond to the humidity changes by removing sufcient amounts of moisture in
order to keep the conditioned space within the comfort zone.
Anytime the compressor is running in air conditioning mode, it will also be pulling humidity out of the space. Fixed‑speed
systems shut off after the desired set temperature is reached (i.e. when the sensible load is met). VRP® units run much
longer at lower capacity and energy consumption than traditional systems. Humidity levels are reduced to more comfortable
levels. The dehumidication capability of VRP units is enhanced through the use of a reheat coil that provides superior
exibility in satisfying a wide range of latent and sensible capacity demands. The reheat coil is placed behind the evaporator
coil.
At relatively high ambient temperatures, both sensible and latent components of the system capacity are required to
satisfy increased cooling and dehumidication demands. The VRP wall controller and other sensors in the unit combine to
continuously monitor the space RH levels and when there is demand for extra dehumidication, the refrigerant exiting the
condenser is rerouted to the reheat coil located behind the evaporator on the way to the indoor air stream supplied to the
conditioned space.
Thus, cooled and dehumidied air exiting the evaporator coil is reheated to desirable comfort levels for the space.

Condenser CFM & External Static Pressure
VRP®is designed to mount through an exterior wall through a Friedrich wall plenum with an external louver.
Building design and applications may require different congurations of this external connection for aesthetic/architectural reasons.
These different congurations may include custom louvers, plenums or special ducted returns.
The following are guidelines for the design of these custom external congurations.

CAUTION: If the Friedrich designed plenum and louver combinations are not used, the louver/duct design must be evaluated to
insure the total pressure drop does not exceed the maximum allowable limits.
