The purpose of this standard is to establish an IEER and SCHE Method of Calculation for Water/Brine Source Heat Pumps. This standard utilizes
the Published, Certified Data, of performance standard ISO/AHRI/ANSI/ASHRAE 13256-1:1998, and includes the definitions; rating requirements;
minimum data requirements for Published Ratings; marking and nameplate data; and conformance conditions required.

RB SERIES ENGINEERING GUIDE
The performance standard AHRI/ASHRAE/ISO 13256-1 became effective January 1, 2000 and replaces AHRI Standards 320, 325, and
330. This new standard has three major categories: Water Loop (comparable to ARI 320), Ground Water (ARI 325), and Ground Loop (ARI
330). Although these standards are similar there are some differences:
Unit of Measure: The Cooling COP
The cooling efficiency is measured in EER (US version measured in Btu/h per Watt. The Metric version is measured in a cooling COP
(Watt per Watt) similar to the traditional COP measurement.
Water Conditions Differences
Entering water temperatures have changed to reflect the centigrade temperature scale. For instance the water loop heating test is
performed with 68°F (20°C) water rounded down from the old 70°F (21.1°C).
Air Conditions Differences
Entering air temperatures have also changed (rounded down) to reflect the centigrade temperature scale. For instance the cooling
tests are performed with 80.6°F (27°C) dry bulb and 66.2°F (19°C) wet bulb entering air instead of the traditional 80°F (26.7°C) DB
and 67°F (19.4°C) WB entering air temperatures. 80.6/66.2 data may be converted to 80/67 using the entering air correction table.
This represents a significantly lower relative humidity than the old 80/67 of 50% and will result in lower latent capacities.
Pump Power Correction Calculation
Within each model, only one water flow rate is specified for all three groups and pumping Watts are calculated using the following
formula. This additional power is added onto the existing power consumption.
• Pump power correction = (gpm x 0.0631) x (Press Drop x 2990) / 300
Where ‘gpm’ is waterflow in gpm and ‘Press Drop’ is the pressure drop through the unit heat exchanger at rated water flow in feet
of head.
Blower Power Correction Calculation
Blower power is corrected to zero external static pressure using the following equation. The nominal airflow is rated at a specific
external static pressure. This effectively reduces the power consumption of the unit and increases cooling capacity but decreases
heating capacity. These Watts are significant enough in most cases to increase EER and COPs fairly dramatically over ARI 320, 325,
and 330 ratings.
• Blower Power Correction = (cfm x 0.472) x (esp x 249) / 300
Where ‘cfm’ is airflow in cfm and ‘esp’ is the external static pressure at rated airflow in inches of water gauge.
ISO Capacity and Efficiency Calculations
The following equations illustrate cooling calculations:
• ISO Cooling Capacity = Cooling Capacity (Btu/h) + (Blower Power Correction (Watts) x 3.412)
• ISO EER Efficiency (W/W) = ISO Cooling Capacity (Btu/h) x 3.412 / [Power Input (Watts) - Blower Power Correction (Watts) + Pump
Power Correction (Watt)]
The following equations illustrate heating calculations:
• ISO Heating Capacity = Heating Capacity (Btu/h) - (Blower Power Correction (Watts) x 3.412)
• ISO COP Efficiency (W/W) = ISO Heating Capacity (Btu/h) x 3.412 / [Power Input (Watts) - Blower Power Correction (Watts) + Pump
Power Correction (Watt)]
Comparison of Test Conditions
Conversions:
Airflow (lps) = cfm x 0.472; Water Flow (lps) = gpm x 0.0631;
esp (Pascals) = esp (in wg) x 249; Press Drop (Pascals) = Press Drop (ft hd) x 2990

RB SERIES ENGINEERING GUIDE
The RB Series
Vertical RB Series
Models RBSV 006-070 (0.5-6 tons) Single Speed
Horizontal RB Series
Models RBSH 006-070 (0.5-6 tons) Single Speed
The RB Series raises the bar for boiler/tower applications by providing flexibility and efficiency into a compact cabinet at a competitive price. A
compact cabinet is important when choosing a replacement heat pump. Many water source heat pumps of the 1980-90’s were relatively low
efficiency models with a small footprint. Once they are installed in a building and piping and ductwork is piped around the unit replacement with
a larger footprint is nearly impossible. The RB Series combines the high efficiency of 21st century product in a footprint that matches a 1980 heat
pump for easy replacement. The chart below shows a comparison of a typical 1980 legacy wshp and current competitor data versus the RB
Series.
This full range product offers all the standard commercial voltages using high efficiency rotary and scroll compressors along with either
3-speed permanent split-capacitor (PSC), 5-speed ECM, or variable speed ECM blower motors.

that brings all aspects of the
HVAC system into one cohesive
module network. Aurora uses
the Modbus communication
protocol to communicate between
modules. Each module contains
the logic to control all features
that are connected to the module.
The Aurora Base Control (ABC) has two Modbus channels. The
first channel is configured as a master for connecting to devices
such as a communicating thermostat, expansion board, or other
satellite devices. The second channel is configured as a satellite for
connecting the Aurora Interface Diagnostic Tool (AID Tool).
The Aurora Interface and Diagnostics (AID) Tool is a device
that is a member of the Aurora network. The AID tool is used to
troubleshoot equipment which uses the Aurora control via Modbus
RTU communication. The AID tool provides diagnostics, fault
management, ECM setup, and system configuration capabilities to
